Problem Statement: What information is contained in Config.dat, Map.dat, and Tune.dat?
|
Solution: Config.dat, Map.dat, and Tune.dat are located in “C:\ProgramData\AspenTech\InfoPlus.21\c21\h21\dat”.
Config.dat contains configuration information on the history repositories and file sets, most notably, their location and number. When the database is up and running, the information in config.dat is stored in memory. On startup, the information in config.dat is loaded into the database via the history system. On shutdown, any information the user modified via the InfoPlus.21 Administrator is saved back into config.dat from the database via the history system.
Note: If config.dat is deleted, then subsequently starting and stopping InfoPlus.21 will result in the creation of a new config.dat that defines one history repository, TSK_DHIS, with the three archives.
Map.dat contains the information that maps data from repeat areas of records to archives and vice versa. This file is absolutely necessary to access archives from a database and is specific to a snapshot. Warning! In order to ensure that you do not lose history due to loss of the map.dat file, it is imperative that you retain a backup copy of the map.dat file. If map.dat is deleted, it will be recreated, but it will not contain the correct map indices, which will result in a loss of history.
Tune.dat contains the tuning information for archives such as minimums and maximums. It is not a crucial file and will be recreated if deleted.

Problem Statement: What information is contained in Cache.dat and Event.dat?
|
Solution: Cache.dat and Event.dat are located in “C:\ProgramData\AspenTech\InfoPlus.21\c21\h21\arcs” (or wherever a repository is created).
Cache.dat is the cache “overflow” file. If the database runs out of space in the memory resident cache, data is written to this file. The cache is where the h21archive.exe temporarily stores historical events to be archived before writing them to disk. It writes to cache while CPU time is precious and then empties the cache to disk when the system resources are not at a premium. Cache is written to disk every five minutes and when database is shutdown. This file is recreated when deleted when the repository is started up.
Event.dat is the queue “overflow” file. If the database runs out of space in the memory resident queue, data is written to this file. The queue is where repeat area values THAT ARE NOT ARCHIVED but still in resident memory are stored. The archive then pulls data out of queue and puts it in the repository or a temporary cache.

Problem Statement: A limitation in the VB script language is that natural log function is not supported in VB script. Aspen Calc supports programming in both Calc script and VB script but only Calc script has the capability of using both Log and Log 10 functions.
|
Solution: An easy workaround for this problem is to use the formula Log X = Ln X / Ln 10 and therefore Ln X = 2.303 * Log X. This can be used in VBscript in the following syntax Log10_X = Log (X) / Log(10)
Note:
For current versions (V10, V11, V12) VB does support both Log and Log10 functions. this has been tested for AspenCalc and IQ

Problem Statement: APEM does not like certain characters in a text field
|
Solution: Users must avoid entering the XML special characters in a text field such as: <, >, ', , and &.
If the text field contains any of these characters the following problem could happen. The text value is sent to APRM and is enclosed in an XML message so these characters can cause the data extraction to fail on the APRM side.

Problem Statement: How does the “include subfolders” option of the Tag Browser works?
|
Solution: Inside Tag Browser | View | Options under Search tab there is an option named “Include Subfolders” ( see image below). This option can cause confusion because if it is not selected, users can believe that it will exclude the tags that are associated to a folder.
When the “Include subfolder” box is checked, then on Tag browser you will need to highlight a specific folder and click execute, then only those tags that are associated to that folder will be returned.
If no folder is selected, the tag browser will get all tags created on IP.21 Administrator even if the “include subfolders” box is or not checked.

Problem Statement: Most connection issues with the Aspen Calc server connectivity involve Microsoft Windows security settings. Since the applications rely on Microsoft DCOM to communicate with Aspen Calc servers across a network, connection problems are likely related to incorrect firewall or DCOM permission settings.
|
Solution: The document attached to this KB article describes the steps to configure Aspen Calc applications to communicate with remote Aspen Calc servers.
The Aspen Calc Configuration application (thick-client user interface) and the web application allow users to connect to the Aspen Calculation Scheduler service on computers throughout a network. Once connected, users can manage the Calculation Scheduler either from the thick-client or from the web application.
Both applications make connections to external Aspen Calc servers using Microsoft’s Distributed Component Model (DCOM) communication protocol. This communication mechanism requires the opening TCP/IP ports, as well as, proper configuration of DCOM settings. This document describes steps to configure the DCOM permissions to facilitate remote server connectivity.

Problem Statement: The target OPC UA server rejects the untrusted certificate of Cim-IO OPC UA interface processes
|
Solution: This occurs only when a nonsecure endpoint is used for connection, I.E., an endpoint other than None Security Mode and None Security Policy is used.
This can be identified by looking below error message in the log file of Cim-IO processes(read/write/unsol)
Session failure, can't connect to Opc UA server:... Exception:Opc.Ua.ServiceResultException: Error establishing a connection..
All certificates of the Cim-OPC UA interface processes (read, write and unsol) must be trusted by the OPC UA Server. The instructions on how to trust the client certificates must be provided by the vendor of the target OPC UA Server.
You can take a look to the KB article Example using CIM-IO for OPC UA to get data from one Aspen InfoPlus.21 to another to see how to export the Cim-OPC UA interface processes (read, write and unsol), also this instructions might be quite similar on vendor’s steps you can use it as a guidance but each vendor has their own procedure to trust client certificates.

The Cim-IO OPC UA interface processes try to connect to the target OPC UA server as soon as the Cim-IO OPC UA Interface is started. Any connectivity issues can be identified as soon as the interface is started.
In pre-V11 versions.
Cim-IO OPC UA interface processes does not connect to the target OPC UA Server when the Cim-IO for OPC UA interface is started. The Cim-IO for OPC UA interface processes connect to the target OPC UA server only on receiving the first request from the Cim-IO client processes on the IP21 server.

Problem Statement: Query example to move a tag from one repository to another repository
|
Solution: Before changing the repository of a Tag take a look to the following Kb article What are the consequences of moving a tag from one repository to another repository?
In order to change a tag from one repository to another you should do the following:
Turn OFF the IP_ARCHIVING.
Change IP_REPOSITORY to point to the new repository desired.
Turn ON the IP_ARCHIVING.
The following script can be used in Aspen Sqlplus in order to change the repository of a tag.
Please run the steps separately.
UPDATE IP_ANALOGDEF SET IP_ARCHIVING = 'OFF' WHERE NAME = '<TagName>';
UPDATE IP_ANALOGDEF SET IP_REPOSITORY = '<RepositoryName>' WHERE NAME = '<TagName>'
UPDATE IP_ANALOGDEF SET IP_ARCHIVING = 'OFF' WHERE NAME = '<TagName>';
NOTE: This script works for the tags defined under IP_ANALOGDEF Record, if you want to change the repository of a tag defined under a different record, please change IP_ANALOGDEF to the record you want.

Problem Statement: How often does Aspen Process Data (RDBMS) gets updated when trending in AspenONE Process Explorer or Aspen Process Explorer?
|
Solution: By default Aspen Process Explorer update every 7 seconds, but sometimes tags retrieve data in a different frequency, so in order to reduce the network traffic to the database, a column named RefreshRate can be added on SQL server to reduce the number of requests when trending in A1PE or APEx.
The value entered in the RefreshRate column will be recorded as seconds. If this value is zero, then history/current values will be retrieved during every request.
Below you can find the steps to add the RefreshRate column inside SQL Server
1. Open your table on SQL Server and right click on it and choose Design
2. At the end of the rows, add a new one and name it as RefreshRate
3. Save the changes.
4. Now you will be able to see the new column named RefreshRate

Problem Statement: In redundancy environment, is it possible to do a manual switchover between Cim-IO Servers without having ping enable?
|
Solution: For Cim-IO Redundancy, TSK_DETECT performs a ping operation between Cim-IO nodes to see which server is reachable and then it does an automatic switchover.
Some customer doesn’t have ping enable in their servers and want to know if a manually switch over can be performed to change form one node to another one. The answer is no, even though you can do a manual switch over and chose the node that will be connected to IP.21 server, the task detect needs to be sure that the node is reachable, so it will perform a ping operation to see if the Cim-IO Server is available, if task detect is not able to ping to the node then it will assume that is not reachable and you won’t be able to do the manual switchover.

Problem Statement: Even thought there is a Graphic User Interface in aspenONE Process Explorer (A1PE) V10 to fetch data into an OEE record, sometimes the information to fetch in is in a .CSV file and might take some time to insert manually the information of several events in A1PE.
|
Solution: The query attached on thisSolution inserts the information that is necessary for the OEE events into a specific OEE record.
Please check these instructions that explain the way in which you must enter data in a .CSV file and what you need to change in the Aspen SQLplus Query attached that will be used to insert data into the OEE event.
An OEE record has to be created in A1PE (It is recommended due to the fact that it makes it easier to enter customized lists and a Target for production).
The .CSV file has the following structure:
Notes:
Before entering data, confirm that the format of the spreadsheet is set to Text. This is very important because SQLplus will read the information as a Text and there is no need to convert data to its corresponding format, for example, it is not necessary to use ‘cast’ command to convert the text of the cell to a timestamp.
Make sure that the events do not overlap each other. A1PE will consider that any time Gap as Off Time, so please confirm that there are no gaps in the data and no overlaps between events.
For timestamps, make sure that you are using the correct format of IP21. In order to do it, open IP21 Administrator, right click on Database name > Properties > Time parameters tab. This is an example of my system:
Here is a brief description of every Colum and how to enter data in .CSV file:
OEE_EVENT_START: The start date of the event.
OEE_EVENT_END: The end date of the event.
OEE_EVENT_EQUIPMENT: You must enter the name of the equipment (from the list that you entered in A1PE). This is only for “Unplanned Downtime” and “Planned Downtime” events.
OEE_EVENT_TYPE: You can only enter one of these values: Production, Off Time, Planned Downtime and Unplanned Downtime.
OEE_PERFORM_ISSUE: It only applies to Production events and it is the most important issue that affected the event. You must put a value from the list “Performance Loss Issues” that you created in A1PE.
OEE_QUALITY_ISSUE: It only applies to Production events and it is the most important issue that affected in Quality losses. You must put a value from the list “Quality Loss Issues” that you created in A1PE.
OEE_EVENT_TARGET: It only applies to Production events and is the target that you have for a production. It can be equal to the Ideal target that you set when creating the OEE record in A1PE or less than the ideal. It cannot be greater than the ideal.
OEE_EVENT_ACTUAL: It only applies to Production events. Is the real production that met the specification.

Solution: can be performed in these functions: Current Value, Historical Value, Historical Values and Calculated Values.
Solution
1. Open a new Excel spreadsheet and click on the Aspen Process Data tab
2. Select one of the functions described above. In this example “Historical Values” function was selected:
3. On the right-side pane, in the tag field, type the Ad-Hoc calculation starting with the “=” symbol. In this example the expression “=atcai + 10” was entered, where “atcai” is the name of the tag,
so 10 units will be added to the historical values of that tag when displaying them in the sheet:

Problem Statement: Even thought there is a Graphic User Interface in aspenONE Process Explorer (A1PE) V11 to fetch data into an OEE record, sometimes the information to fetch in is in a .CSV file and might take some time to insert manually the information of several events in A1PE.
|
Solution: The query attached on thisSolution inserts the information that is necessary for the OEE events into a specific OEE record.
Please check these instructions that explain the way in which you must enter data in a .CSV file and what you need to change in the Aspen SQLplus Query attached that will be used to insert data into the OEE event.
An OEE record has to be created in A1PE (It is recommended due to the fact that it makes it easier to enter customized lists and a Target for production).
One of the new features in A1PE V11 for OEE is that now you can add a list for Off Time Reasons:
Another new feature is that when a new OEE Record is created, A1PE asks for the format of the Ideal Run Rate, which is a real number. Also, the unit of the Ideal Run Rate has been split into two separate fiels: a quantity unit and a time unit, so if the ideal run rate is 900 GPM, it would be necessary to select “Gal” in Quantity Unit and “Minutes” in Time Unit. Finally, “Off Time Reasons” list must be selected.
The .CSV file has the following structure (Please find attached a example file in this article):
Notes:
Before entering data, confirm that the format of the spreadsheet is set to Text. This is very important because SQLplus will read the information as a Text and there is no need to convert data to its corresponding format, for example, it is not necessary to use ‘cast’ command to convert the text of the cell to a timestamp.
Make sure that the events do not overlap each other. A1PE will consider that any time Gap as Off Time, so please confirm that there are no gaps in the data and no overlaps between events.
For timestamps, make sure that you are using the correct format of IP21. In order to do it, open IP21 Administrator, right click on Database name > Properties > Time parameters tab:
Also, this query can be run in SQLplus:
Write GetDBTime;
And the current time will be returned with the IP21 format.
Here is a brief description of every Colum and how to enter data in .CSV file:
OEE_EVENT_START: The start date of the event.
OEE_EVENT_END: The end date of the event.
OEE_EVENT_EQUIPMENT: You must enter the name of the equipment (from the list that you entered in A1PE). This is only for “Unplanned Downtime” and “Planned Downtime” events.
OEE_EVENT_TYPE: You can only enter one of these values: Production, Off Time, Planned Downtime and Unplanned Downtime.
OEE_PERFORM_ISSUE: It only applies to Production events and it is the most important issue that affected the event. You must put a value from the list “Performance Loss Issues” that you created in A1PE.
OEE_QUALITY_ISSUE: It only applies to Production events and it is the most important issue that affected in Quality losses. You must put a value from the list “Quality Loss Issues” that you created in A1PE.
OEE_EVENT_TARGET: It only applies to Production events and is the target that you have for a production. It can be equal to the Ideal target that you set when creating the OEE record in A1PE or less than the ideal. It cannot be greater than the ideal.
OEE_EVENT_ACTUAL: It only applies to Production events. Is the real production that met the specification.
OEE_EVENT_RATE: This value has to be 0.
OEE_EVENT_LOSS: It only applies to Production events. Is the production that did not met the specification (Quality Loss).
OEE_EVENT_COMMENT: Here you can write all the comments for all the events (Production, Off Time, Planned Downtime, Unplanned Downtime).
OEE_UNPLANNED_REASONS: It only applies to Unplanned Downtime events and it is the most important issue that affected it.
OEE_PLANNED_REASONS: It only applies to Planned Downtime events and it is the most important issue that affected it.
OEE_OFF_REASONS: It only applies to Off Time events and you can select one of the elements of the list for Off Time events, the new feature that is described above.
Notes: When entering numbers, if the event does not require to enter a number, please enter a value of 0:

Problem Statement: Aspen MES Failover Clusters inherently supports AFW security. The configuration depends on whether Local or Enterprise AFW security is to be deployed.
|
Solution: With Local AFW, the security policies are maintained on the clustered IP21 server and stored in a local database file that resides on the cluster shared disk.
With Enterprise AFW, the security policies are maintained on a separate server from the clustered IP21 servers. The security data is stored in a relational database, such as SQL Server separate from the MES cluster. On the owning node of the MES cluster, configure the external AFW server settings by following the AFW configuration documentation as would be done for a non-clustered IP21 system.
In both cases, the configured AFW settings are stored in the Windows registry. The registry key values are automatically synchronized across the MES cluster nodes. When a failover occurs, the new owning node of the MES cluster will automatically use the configured AFW database as found in the registry settings. So there are no special steps required to use AFW Security in a cluster. Manage AFW security as would be done on a non-clustered IP21 system by using the AFW Security Manager tool on the owning node of the MES cluster.

Problem Statement: Is Pattern Search supported for aspenONE Process Explorer V11 32-bit?
|
Solution: Pattern Search is a new, alternative method of searching for patterns versus Pattern Discovery or Pattern Recognition. This feature was introduced in A1PE V11.
Pattern matching analytics allows you to:
Select data trends in a time period and have the system search similar shaped trends in a fixed history.
Identify a data trend over a period as a pattern signature for future re-use with any other data sets or tags.Signatures are kept in the Signature Library.
This feature can be entered through any aspenONE Process Explorer page by clicking the Pattern Search icon . Note that some pages, such as Graphics, do not have the Pattern Search icon:
Pattern Search is supported in 64-bit only, so in order to use Pattern Search and a 32-bit version of A1PE is used, it would be necessary to uninstall the 32-bit version and install a 64-bit version.

Problem Statement: What is the function of the external task TSK_HIST_RECOV?
|
Solution: In some old Aspen InfoPlus.21 systems, there is a external task called TSK_HIST_RECOV.

Select CAST(TS AS CHAR FORMAT 'DD-MON-YY HH:MI:SS') as Timestamp, Value From History -- On this line the Timestamp and Value are selected from the History Table (History)
Where TS between '21-JAN-19 12:05:57.8' and '21-APR-20 12:05:57.8' --Here the period of analysis is written, starting with the oldest date.
and Name = 'atcai' --Here is the name of the tag
and Stepped = 0 --0 is the default and means that the data is treated as analog or continuous. 1 is for discrete or stepped
and Request = 6 --Used only when stepped = 1.
and period = 00:01:00; --Here is the sampling time (1 minute for this example)
You can find more information about the parameters of the History Table in the SQLplus Help.
If you want to send the output to an excel file you can add these lines to the previous query:
SET COLUMN_HEADERS = 1;
SET VALUE_BETWEEN =',';
SET HEADER_BETWEEN =',';
SET HEADER_LINE = '';
SET Output 'C:\temp\Sampling.csv'; --Here you configure the CSV file for the output

Problem Statement: How do I use the user submodel option to implement the reaction kinetics in gas_bed model?
|
Solution: The first example C4Dehyd-props.ada is based on the demonstration example butene dehydration. It is using Aspen Properties instead of fortran procedures for the physical properties. It is also using the submodel option for the kinetics instead of fortran subroutine.
The equations for the kinetics are implemented in the flowsheet constraints, in a similar way as other submodel models (e.g. user isotherm).
The second example shows the reaction of ZnO + H2S --> ZnS + H2O. The data are arbitrary, the example is only for illustration of the workflow.
In the gas_bed Layer configuration, on the Reaction tab, you need to select the appropriate options:
The reaction kinetics are implemented in the flowsheet constraints:
We use the following code:
CONSTRAINTS
// Flowsheet variables and equations...
stoicg([1], componentlist) as realparameter (0);
stoicg(1, H2S) : -1;
stoicg(1, H2O) : 1;
stoics([1], B1.Layer(1).Reaction_Cat(1).User_RX_Rate_Pp_Sol(1).SolidComponentList) as realparameter (0);
stoics(1, ZnO) : -1;
stoics(1, ZnS) : 1;
k0 as realvariable (fixed, 0.001);
within B1.Layer(1).Reaction_Cat(1).User_RX_Rate_Pp_Sol(1)
for i in FDESet do
//for reac in ReactionSet do
// Rreac(i, reac) = 0;
//endfor
Rreac(i, 1) = k0 * Csol(i, ZnO) * p(i) * y(i, H2S);
for comp in componentlist do
Rcomp(i, comp) = sigma(foreach(reac in ReactionSet) stoicg(reac, comp) * Rreac(i, reac));
endfor
for comp in SolidComponentList do
Rsol(i, comp) = sigma(foreach(reac in ReactionSet) stoics(reac, comp) * Rreac(i, reac));
endfor
endfor
endwithin
// Heats of reaction
within B1.Layer(1).Heat_Reac_Cat(1).User_RX_Heat(1)
for i in FDESet do
for reac in ReactionSet do
Hreac(i, reac) = -75.500; // MJ/kmol
endfor
endfor
endwithin
END
You can watch on the solid profile plot (in Flowsheet folder) the conversion of ZnO to ZnS. When all ZnO is consumed, you will see the breakthrough of H2S in the outlet stream (composition plot).

Problem Statement: There is detailed information for each available property method and models in Aspen Plus and Aspen HYSYS, but how does one pick the best property method to use in the model?
|
Solution: There is a Methods Assistant available in the Help guide. Also accessible from Home | Tools in Aspen Plus and from Home | Navigate in Aspen HYSYS.
The purpose of the assistant is to help users select the most appropriate property methods for use with Aspen Plus and Aspen Properties. The assistant will ask you a number of questions that it uses to suggest one or more property methods to use.
Often there is not one single method suggested. In some cases, there are process-specific versions of some of the property methods; however, it is the user's responsibility to select the property method based on the information available. In many cases, there is a company preferred property method based on past modeling experience.

Problem Statement: This knowledge base article describes how the time out mechanisms work between the SLM License Server and the client machine.
|
Solution: The SLM client (client Computer) uses a heartbeat to ensure that the server remains available throughout the use of the software. The heartbeat does a check (for the server and license) every 4 minutes. If the heartbeat finds that the license is still there, the software will keep working. If the heartbeat does not find a license after 3 consecutive tries (12 minutes), the software will generate the error saying that it lost contact with the license server.
The License Server watches for that heartbeat. If it doesn't hear from the client computer within a certain time frame, then it releases the license back to the pool so that someone else can use it. That time frame is the key lifetime, which is set to a value of 5 minutes. This means that if the product crashes, if the network connection is lost, or if for some other reason the license is not properly released, the server will hold the license for 5 minutes before releasing the license back to the server.
The heartbeat and key lifetime values are hard coded into the license file and so cannot be changed on the license server computer or the client computer.

Problem Statement: What is “The Unit Procedures Diagram” in Aspen Plus Batch Process and how to use it ?
|
Solution: The Unit Procedures Diagrams are available as option to observe the various batch operations you have planned in BatchOp blocks (major steps – Unit Procedure) such as Reactions, Crystallization, Filtration where you can define these as unit procedures & in each procedure users can define various operations like charge, heat, cool etc as operations.
Such operations could be easily observed using these unit procedure diagrams and easy to monitor the progress of batch recipes rather than to go in each & every unit procedure.
At the bottom of the Unit Procedures object manager, the Configure sheet of every unit procedure, and the Configure sheet of each operation is a diagram showing a visual representation of the batch schedule. This diagram shows when each procedure runs relative to all other procedures. Initially, this diagram is displayed in a collapsed state, where all the operations in each unit procedure are displayed in one line:
If you click the triangle icon to the left of each unit procedure, it expands to show the operations within it:
The rectangles represent operations which take a specified time and the length of each rectangle is in proportion with this time. The diamond icon represents an operation whose duration depends on a process variable and thus is determined during the run.
Note: This diagram represents the input times. When there are triggered operations, some operations may not appear at their correct times relative to operations in other unit procedures. A similar diagram showing the results (and therefore having the actual timing for each operation) is the Unit Procedure Operating Schedule available by clicking Operating Schedule in the Batch tab of the ribbon.
If the unit procedure does not start at time 0, a shaded rectangle (for a specified delay) or diamond (for a delay based on a process variable) appears:
When you hover the mouse over the name of a unit procedure, the description of that procedure (if provided) is shown. If you hover over the name or one of the rectangle or diamond icons, a summary of the operation or delay it represents is shown. You can click each rectangle and diamond icon corresponding to an operation to jump to the form for that operation.
When you are ready, you can run the batch flowsheet.

Problem Statement: Users may notice their separators initialize to high temperatures when moving from steady-state to dynamics.
|
Solution: Per the HYSYS Dynamics Best Practices KB article ID 000094883 , a vapor phase will be needed in separators. Consider if you will need to add inert components to pressurize the vessel.
During initialization, the separator will calculate a vapor phase. If no vapor is present at the specified conditions, then it will increase the temperature until it produces a vapor. The temperature will correspond to the boiling point of the lightest component at the specified conditions. If there are only heavy components in the system, then it will initialize to a high temperature.
Add an inert component, e.g. nitrogen, to occupy the vapor phase and pressurize the vessel. Once this is done, the separator will initialize at the expected temperature in HYSYS Dynamics.

Problem Statement: How can I include Equipment Shape and Equipment Footprint data into my Spreadsheet Import/Export Report?
|
Solution: ACCE’s Speadsheet Import/Export Report, or API Report, has the capability of printing Equipment Shape and Equipment Footprint when the “Print equipment coordinates” option is set to “Y”.
You can find this option at the bottom of the “Equipment Specs” Form “ under Project Basis View.
Both Equipment Shape and Equipment Footprint data are important pieces of information to transfer data from ACCE into OptiPlant.
To write this information in the Excel Report, please select “Export data + plotplan results” in the Spreadsheet Import/Export Window menu.
Once the report is generated, you will be able to find data for Equipment Footprint and Equipment Symbol Shape information for the different pieces of equipment present in the ACCE Project.

Solution: 2D DXF Import Check List
Check list for importing 2D DXF into OptiPlant. Please check on all that apply.
A. Pre-requisite for Importing DXF
1 DXF File being imported is in lower version of AutoCAD (AutoCAD 2007 earlier)
2 Drawing file has only lines, lines, arcs, circles and text present. All poly lines, hatchings, multi-line texts, ellipses have been exploded from the file.
3 Drawing file does not have any referenced data and unused items, such as block definitions and layers.
4 The working unit in OptiPlant Project is same as that used in Drawing file.
5 Scale of the drawing is 1:1
6 The plot-plan co-ordinates of the OptiPlant plot plan is set to match the maximum and minimum X and Y co-ordinates of the 2D DXF file
7 If the answer is YES for all of the above, skip Step B and go directly to Step C
B. Processing the DXF
1 Set the scale of the drawing to 1:1
2 OptiPlant Project coordinates match with the drawing file Min and Max X, Y coordinates
3 Drop/explode all elements by selecting the entire layout present in the DXF file and click on EXPLODE option in AutoCAD.
4 Use the PURGE option in AutoCAD to delete all reference data and delete any extra levels/layers with data not needed for reference
5 Drawing file does not have any referenced data and unused items, such as block definitions and layers.
C. Importing the DXF
1 The correct DXF file is imported to the OptiPlant project folder using DXF Import option and browsing to the correct folder location
2 Any reference to old DXF is removed using the Detach DXF option
3 The imported DXF is being viewed in OptiPlant using Fit View option, Top View and the Draw Style is changed by right clicking on the grid to Wireframe mode
4 Fit View in model was appearing distant and not centered. The contents of the DXF file was copied to a new blank DXF file to remove stray line segments and imported again.

Problem Statement: Does Aspen Flare System Analyzer support Net Heating Value calculation?
|
Solution: In Aspen Flare System Analyzer V11, there is a new feature that supports Net Heating Value (NHV) calculation.
The NHV for Flare Tip and Tee can be calculated with saved phase properties data. A warning will appear on the Flare Tip Editor or Tee Editor if the Save Phase Properties option on the Preference Editor | General tab is not selected. If you are opening a file from an older version of Flare System Analyzer, then you must select the update component databanks option to enable NHV calculation. For hypothetical components, you must manually enter the heat of combustion on the Component Editor | Identification tab. The heat of combustion values can be viewed on the Inputs | Components tab at the far right of the table. If the heat of combustion is not entered for hypothetical components, then the NHV calculation will ignore hypothetical components i.e. assume the heat of combustion is zero. The calculation will be based on all components present in the flare with specified values for heat of combustion.

Problem Statement: Is it possible to attach a reaction set to a HYSYS fluid package imported from Aspen Plus?
|
Solution: No, it is not possible to attach a reaction set to a HYSYS fluid package imported from Aspen Plus. The following error message will appear.
As a workaround, you can copy the imported fluid package. This will allow you to attach a reaction set, but any regressed or estimated parameters in the fluid package will be overwritten with the database values.

Problem Statement: How to add a background to drawings in the Drawing Editor?
|
Solution: In the graphics definer, you can create a symbol then select Insert | Object and add a bitmap image (.bmp). The image must be a bitmap file otherwise a link to the image will be added instead of the image itself. Typically, you can use File | Save As bitmap image (.bmp) in any photo application. Sheet size should be the same in the Graphics Definer (File | Sheet Setup | Size and Scale) and the Drawing Editor (File | Properties | Sheet Size). This ensures the background is the correct size. Once the symbol is added to the library, you can use it as a background.
In the drawing editor, add the background symbol to the drawing first. This will put it at the back of the drawing. Then add other symbols and labels that will overlap the background. To make it easier to select objects move the background image outside of the sheet border, complete the drawing, then drag the drawing back onto the sheet.

Problem Statement: How to align text and fields for labels in Graphics Definer?
|
Solution: One method is to enable Grid Snap under Tools | Options | View | Grid. Select the checkbox for Grid Snap set the insertion point for fields to corners of a grid. Select the checkbox for Grid Display to see the grid in the window. The grid sizes can be changed using Grid Spacing.
When Grid Snap is enabled, fields and shapes will be set along the grid. For example, when adding text fields, they can be aligned horizontally and vertically based on the grid. The cursor will add the insertion point to a corner of the grid.
Then, the text will be aligned in the label.
Additionally, you can go to the field properties (double-click or right click, Properties) and set the exact x and y coordinates for the field. Select the More button and enter the coordinates. If the x values are the same, then the fields will be vertically aligned. If the y values are the same, then the fields will be horizontally aligned.

Problem Statement: How do I adjust the default nozzle projection?
|
Solution: The data file that has the nozzle projection distance value is Rt_param.ans file present inside C:\ASD\Data\ANSI folder. The default value of nozzle projection is based on the pipe size and is equal to Gasket Thickness (1mm) + Large Radius (mm) + Weld Neck Flange (mm). This can be modified, if needed.
If you want to change the projection distance for all the projects, you can change it directly in ANSI folder but if the change is only related to this project then you should copy this file to the project folder and then make the change there.

Problem Statement: Why is an object deleted when I select UnClaim? When an object is exclusively claimed by a project, there can be instances when selecting UnClaim deletes the object.
|
Solution: This problem occurs when an object is created in a project rather than the workspace. If an object is created in a project, then it is claimed by that project instantly. All changes made to the object will be claimed by that project. When you UnClaim an object, it will undo all changes made to the object. For objects created in a project, this includes the creation of the object. Therefore, the object is deleted when you UnClaim it.
A warning will be given before you UnClaim an object.

Problem Statement: After loading the process data to the AI Model Builder tool, specifying dependent and independent variables, and cleaning the data, some observations in the data validation section of the AI Model Builder are repeated, even if those were not repeated in my original data.
|
Solution: Once you have done the Clean Data step for AI-Driven Hybrid Models (such as Average and Steady State Detection), and move to validate it; you may have noticed that some points are repeated. This is due to the nature of the Data Analysis Tools that require the data to be evenly spaced in time.
If the added points are not evenly spaced in time, then the AI Model Builder will automatically add points to the data to correct that.
The way the AIMB decides where to add the points is by finding the smallest interval in the data set and adding the points there. These points keep the values constant from the last original data point.
This is prone to happen especially when you have some observations with missing data.

Problem Statement: Aspen Watch Event log showing MSCWatch License message every minute.
AWServer System Centralized Monitoring: CM Request is OFF. MSCWatch LICENSE 0.00000 0.00000
|
Solution: Starting V11 the Aspen Watch Centralized Monitoring key (SLM_RN_APC_MISC_EM) is being check for miscellaneous tags.
The task responsible for the license check is TSK_MSC1 under IP.21 Manager.
In the event of the license error shown every minute a possible cause is that the task (MSCWatch.exe) is crashing and the system is set to Auto restart the task.
To fix this problem follow the next steps:
Confirm the SLM_RN_APC_MISC_EM key exists on your license server.
Stop TSK_MSC1 from IP.21 Manager.
Navigate to C:\ProgramData\AspenTech\APC\Performance Monitor\etc\cfg and delete the CENTRALIZEDMONITORING.2st file.
Start the TSK_MSC1 from IP.21 Manager
The CENTRALIZEDMONITORING.2st file is an encrypted file that stores the license state and you could have an old or corrupt file that is preventing the task from running properly.

Solution: Because Aspen Plus V11 was compiled with the Intel Fortran compiler 2017 and Microsoft Visual Studio
2017 as a 64-bit program, compiled user models MUST be rebuilt as 64-bit. Files (.obj or .dll) compiled using 32-bit that ran in V10 and earlier will not work.
The Intel Fortran Compiler can be configured to compile as either 32-bit or 64-bit, so generally, a new compiler will not be necessary. The compiler is configured to compile as 64-bit using the Set Compiler for V11 utility in the Aspen Plus folder of the Start menu. The list of options is determined by the compilers64.cfg file. Other configurations involving other versions of Intel Fortran and Microsoft Visual Studio are periodically added, and the updated file can be obtained from KnowledgebaseSolution 131011.
If older 32-bit versions of Aspen Plus (V10 and earlier) are also installed on a computer, it is possible to compile in 32-bit using aspcomp and asplink using the Customize Aspen Plus V10 window and compile in 64-bit using the Customize Aspen Plus V11 window. The key is to use the appropriately compiled files in the correct version of Aspen Plus.
Also note that starting in V11, integer variables in user model interfaces are now 64-bit integers. Integer variables used to store Hollerith strings are 64-bit but use only 32 of those bits to hold four bytes per declared variable. If you have declared variables for user models as INTEGER*4 or LOGICAL*4, you must change these declarations to INTEGER or LOGICAL for your code to work in V11. REAL*8 or DOUBLE PRECISION variables are still 64-bit. In addition, we now use the default calling convention, not the CVF calling convention.
See Maintaining User Routines in the Aspen Plus System Management Guide and Chapter 1 of Aspen Plus User Models for information about compiling Fortran for Aspen Plus.

Problem Statement: This article explains about the Best Practice for the application scope of Aspen Process Recipe and Sequencer implementation.
|
Solution: When developing control strategies and packages with Aspen Process Recipe Explorer, below are the typical implementation sizes from our project experience.
a. Number of Blocks in a single Package: 50-100 Blocks
b. Number of Data
Keywords: Aspen Process Recipe
Aspen Process Sequencer
Application scope limitation
Best Practice
References: points in the package: 500-700 Points
c. Number of Equipment: Up to 2 equipment (typically running one or two packages simultaneously)
* If your planned application greatly exceeds any of these numbers, it may lead to slow application response or intermittent communication failure.
Therefore, we recommend keeping the above limitations in mind when considering the use of Aspen Process Recipe and Aspen Process Sequencer.

Problem Statement: What could give a failed status when trying to use an older version's BCI xml file in newer versions like V11 and V12?
|
Solution: The newer versions of BCI have been upgraded to msxml6 from msxml4. In the old version, the root node BP_Document will append “:xsi” after “xmlns” automatically, then the BP_Order node won’t have the blank xmlns attribute as seen in the newer versions below:
On the new version, the default Revised schema file has a change for the name space field. Taking a look at the below picture, if Xmlns is replaced with xmlns:xsi, then the BP_Order node won’t have the blank attribute.
This file is under the MBO installed folder: C:\Program Files (x86)\AspenTech\Aspen Refinery Multi-Blend Optimizer\XmlSchemaRevision.xml
So the workaround would be to remove the unnecessary revise action nodes ( the 2nd and 3rd lines struck using the blue lines in the image) and just keep the change for BP_Document. .

Problem Statement: With the ELECNRTL property method, the Clark model is used to calculate the mixture liquid molar volume. So regressing the RKTZRA and VLCLK parameters have a direct effect on the mixture liquid molar volume. However, it looks like manipulating the RKTKIJ parameters for pair of molecules also has an effect on the density. I would indeed expect RKTZRA and the VLCLK parameters to have a direct effect on the mixture liquid molar volume. However, if you look at the Clark model description in the documentation of old versions of Aspen Plus, it does not mention anywhere that the RKTKIJ parameters are used anywhere, as most of the calculation either use the pure component molar volume, calculated by the pure component Rackett model, or the VLCLK parameters, to account for the presence of ions.
For example, only the RKTKIJ for solvent/HNO3 have an effect on the mixture density, not the ones for water/solvent or water/HNO3.
|
Solution: The documentation was not quite right about the Amagat's rule. For solvents that are not water, the Rackett (mixture) model is used. For water, the steam-table is used. The two values are then combined using the Amagat rule.
The documentation has been updated and now reads:
The Clarke model calculates liquid molar volume for electrolytesSolutions. The model is applicable to mixed solvents and is based on:
Molar volume of molecular solvents (equation 1)
The relationship between the partial molar volume of an electrolyte and its mole fraction in the solvent (equation 2) All quantities are expressed in terms of apparent components.
Apparent Component Approach
For molecular solvents, the liquid molar volume is calculated by:
Vm,l = xw Vw* + xnws Vnws,l (1)
Where:
Vw* is calculated using the steam table.
xnws is the sum of the mole fractions of all non-water solvents.
Vnws,l is the liquid molar volume for the mixture of all non-water solvents. It is calculated using the Rackett equation.

Problem Statement: What value is used for gas constant in Aspen Plus?
|
Solution: The molar gas constant (also known as the gas constant, universal gas constant, or ideal gas constant) is often denoted by the symbol R. It is a physical constant that is featured in many fundamental equations in the physical sciences such as the ideal gas law and the Arrhenius equation.
In Aspen Plus, the gas constant has a value of 8314.33 J/kmol-K in the SI units used in Aspen Plus internal calculations. This uses the absolute or international Joule and kmoles rather than moles for consistency with the mass unit of kilograms, to ensure the molecular weight has the same value for all units sets.

Problem Statement: How to resolve Failed call to iAtBatchDataSource: get_Areas error received in aspenONE Process Explorer (A1PE) while trying to create a single event trend?
There is one line in the log traces on the web server (i.e. Access Denied): AtAPRM_Query::GetStartEndTimeChars - Failed call to IAtBatchDataSource::get_Areas: Access is denied. (0x80070005)
|
Solution: Steps:
This issue is caused by DCOM settings.
To troubleshoot this issue, on the Aspen Production Manager (APRM) server enable DCOM logging to confirm the cause is DCOM permission related - see How to turn on DCOM logging using a GUI to troubleshoot MES client access issues? From the client machine, invoke the error again by opening the single event trend plot on A1PE and reproduce the error.
On the APRM server, in the event viewer, you will find the DCOM related errors getting logged -
To solve these errors, follow the below steps -
1. On the APRM server, launch component services.
2. Go to the 'My Computer' COM Security tab, verify that Access permission is granted for ANONYMOUS LOGON and it has both local & remote access.
3. Also verify that Edit the launch and Activation limits have all permission granted to ANONYMOUS logon-
Once permissions have been granted/verified, open A1PE again and create single event trend and user should now not have any error message.

Problem Statement: Does Aspen Plus report the actual (true) amount of the Dimer formed when using Hayden-O'Connell (HOC) or Nothnagel (NTH) equations in the vapor phase?
|
Solution: There is no direct way to print out the true vapor phase concentration for dimerization in the Results Summary or Report file. However, if you increase the physical properties diagnostics (Setup | Specifications | Diagnostics) to 8, the History (.his) file will print out component mole fractions based on input and true species as shown below.
Example:
A Vent stream containing (1) Nitrogen, (2) Water, (3) Acetic Acid:
From the attached file, the Vent stream summary shows the the apparent component concentration as follows:
(1) 0.9618355
(2) 0.0377367
(3) 4.27827E-4
From the .his file:
DETAILED PRINTOUT FROM ES22
INPUT MOLE FRACTIONS OF 3 MONOMERS 1: 0.96184 2: 0.03774 3: 0.00043
TRUE MOLE FRACTIONS OF 3 COMPONENTS 1: 0.96053 2: 0.03745 3: 0.00029
Using the Apparent approach, the rounded Input Mole Fractions of the three monomers adds up to one.
The True Mole Fraction of the dimer then would be the difference:
1 - 0.96053 - 0.03745 - 0.00029 = 0.00173.
Notes:
Users can also investigate the Hayden O'Connell and Nothnagel literature for the use of the constants that appear in the Report file. Usually the degree of dimerization is not experimentally measured. Instead another quantity such as vapor heat capacity is used to regress the constants. See Chapter 1of the Thermodynamic Property Methods and Models

Based on the following assumptions:
Steady state
No x flux, z flux
No chemical reaction
Above assumption reduces to the following equation:
(2)
Now for binary system (A and B)
As layer is stagnant thus NB = 0
Using equation above equation can be reduced to the following:

Problem Statement: When trying to open a Heat Exchanger file created in older versions it may be encountered an issue with opening the file. The old Aspen Heat Exchanger files like e.g STX, TASC and BJAC can´t be opened in Aspen Exchanger Design and Rating ( EDR). To open these extensions from these old Heat Exchanger files to the Aspen EDR program, a File Conversion Utility is available.
|
Solution: The name of the utility is SaveAsEDR.exe, and it can be found in the same folder where the EDR program is installed in.
In V10.1 and previous versions, the default location for this folder would be C:\Program Files (x86)\AspenTech\Aspen Exchanger Design and Rating V(Corresponding Version)\XEQ
In V11 and newer versions, the folder location would be C:\Program Files\AspenTech\Aspen Exchanger Design and Rating V(Corresponding Version)\XEQ
The file conversion application can read various Heat Exchanger file types ( TASC (*.tai), ACOL (*aci), APLE (*.api), FIHR (*.fhi), MUSE (*.mui), BJAC (*.bjt), STX (*.sti), and ACX (*.aci) ) and convert them to an EDR file (*.edr) that can be read into the program:
To convert the file, it must be chosen from its source location, select the source destination where the new converted EDR file will be generated and click on the Convert button.
Note: Within STX the baffle cut is entered as a percentage area (unless the No-Tube-In Window, NTIW option is used where the percentage cut is used), whereas in Shell and Tube it is always entered as a percentage cut. In the conversion utility, the baffle cut may not be correctly converted from an area to a cut.
If there are tubes in the window, then the baffle cut is not correctly converted to Shell and Tube, where the value for the percentage area is incorrectly passed across as the percentage cut.
From within STX, the percentage cut (based on the percentage area) can be found from the STX Result in the Main tab, where from line 33 the baffle cut is shown as either the Fraction diameter or the fraction of area.
Once the file has been converted, the Shell and Tube file should be checked to ensure the correct percentage baffle cut is used in the Input | Exchanger Geometry | Geometry Summary | Geometry tab or the Input | Exchanger Geometry | Baffles/Supports | Baffles tab.

Problem Statement: In the Design tab Data of a tee or a mixer within the Aspen Hydraulics sub-flowsheet, there is a solver variable called Partial Body On Flow Area, It is needed to understand what it means before checking it
|
Solution: Partial Body on Flow Area is used to calculate pressure drop due to expansion/contraction caused by the change in diameter from inlet to tee/Mixer body. With Partial Body on Flow Area checked, the solver assumes that the inlet flow expands/contracts to a partial area of the tee body which is calculated from the flow rates of each inlet. If this option is unchecked, the solver will assume the full area of the tee body.

Problem Statement: How to use Aspen Plus with automation when using the EO re
|
Solution: strategy?Solution
It is possible to control Aspen Plus from Visual Basic, or Visual Basic for Applications (VBA) through the automation interface. ThisSolution explains how to implement this when the reSolution strategy is Equation Oriented (EO), as this differs from the way this can be done when the reSolution strategy is sequential modular (SM).
Currently this feature is not documented.
See attached zip eo-automation-V12.1.zip file which contains:
a spreadsheet with VBA code for Aspen Plus V12.1
a word document to explain how this works
a bkp to be used with the example for Aspen Plus V12.1
On Sheet1 the example shows:
how to open the simulation and do a run in SM
change variable values for EO
get variables values from EO
create objective function
change the run mode (SIM, OPT)
run the simulation in EO reSolution strategy
On the Sheet3 code, there is another example to show how to repeat EO runs, to mimic the sensitivity analysis as it is done in SM run mode.

Problem Statement: When trying add new locations to my asset hierarchy, my EAM configuration is only returning a list of locations that already have been mapped to the Aspen Mtell database. If I try it on a blank database, an empty result list is returned with no error messages.
|
Solution: This can occur if the user account running the services that are trying to access the EAM system do not have sufficient privileges to the EAM system. The recommended minimum permissions is to be able to read a list of equipment and their hierarchies. No error is generated because the return of objects that can be accessed is a blank list, which is then passed on to Mtell. Existing equipment that match the search criteria are always returned to ensure equipment is not duplicated in the asset hierarchy.

Problem Statement: How HYSYS calculate the water mole fraction content in the effluent Naphtha stream from the Crude Distillation Unit (CDU)?
|
Solution: Naphtha is a draw stream from 3-phase condenser and the calculation is similar to any other draws. Furthermore, the 3-phase condenser is just a column stage and in each stage, Aspen HYSYS will make sure that each of the component flows and the heat flow in and out will be balanced for each stage. Also, for the 3-phase condenser (vapor-liquid-free water phase) are in equilibrium. That's how Aspen HYSYS calculate the column and obtained each component flow.
In 3-phase condenser, most of the water will go to the free water draw phase, but maybe small amount of water can still go to liquid phase, such as in this case Naphtha draw.

Problem Statement: Are there any alternative ways to retrieve stream results other than Stream Reporter (HSR) file in Aspen HYSYS?
|
Solution: There are other ways to retrieve stream results in Aspen HYSYS other than HSR.
The HYSYS Workbook and Model Summary Grid (both in the Home Tab > Summaries section) are the closest equivalent native functionalities to what the HSR provides.
Workbook: This is the native functionality that is most similar to the HSR. It allows you to display properties for streams and unit ops and it can be exported to Excel.
Model Summary: This is similar to Workbook but has much more advanced features, it is customizable, and can be exported to Excel/ASW.

Problem Statement: How to get rid-off the following message “FUNCTIONAL GROUP GENERATION FOR THE UNIF-LBY METHOD CANNOT BE COMPLETED FOR COMPONENT X. THE FOLLOWING ATOMS WERE NOT MATCHED” in physical property system?
|
Solution: The warning message mean that the component pair is not available with UNIFAC and other available methods (for group contribution). Users need to rely only on the experimental values. Due to bonding group unavailability, only experimental values need to be used and regressed.
The reason is that you have selected Estimate all missing parameters in Estimation mode, the software will try all possible calculation methods, including UNIF-LBY. But as the warning shows, UNIF-LBY cannot decompose into functional group representations out, so a warning message is displayed.
If you want to eliminate this message, just select Do not estimate any parameters in Estimation mode:
By default, estimate all missing parameters can be run once, and the estimated results will be saved in the method|parameters folder. So, it is not necessary to select estimate all missing parameters all the time.

Problem Statement: While defining an ion from scratch and providing only CHARGE, IONTYP & S025C a value for MW is shown after retrieving parameters. Has this default value any meaning?
|
Solution: By default, the molecular weight is calculated from the molecular structure.
When PLXANT is set to -1e20, the MW is one of the many parameters defaulted. When the user retrieves parameters, some values are displayed. These nominal values are not truly random. There is nominal value for MW, which is set to 86.178. It's MW of nC6.
The best practice is to enter the molecular formula on the Components | Molecular Structure | Formula sheet.

Frequently Asked Questions

Problem Statement: Is there an option for selecting disc-and-doughnut (disc and ring) baffles in Aspen Shell & Tube Exchanger (EDR)?
|
Solution: Unfortunately, Aspen Shell & Tube Exchanger (EDR) does not have an option for selecting disc-and-doughnut baffles as there is very little reliable data on this type of heat exchanger internal. Since we cannot provide methods for accurately predicting the performance of these baffles, this option has not been included at this time.
As an approximation to model disc-and-doughnut baffles, we suggest using the double segmental baffles instead of single segmental, as this should better match the velocity profiles in the shell. In using this approach, note that you should ensure the flow areas are the same as for the disc-and-doughnut type baffles.

Problem Statement: Sometimes when using Automation with MS Excel, it’s hard to find the backdoor name (or moniker) for an Aspen HYSYS variable. How can I find it in a simple way?
|
Solution: Watch the below video for an overview, or read the instructions further down.
You can create a script using the Script Manager while performing an action involving the variable in Aspen HYSYS, and you will be able to find the backdoor name for it in the text file created for the script.
For instructions on how to use the Script Manager, seeSolution 139395.
Let’s say we want to find the backdoor variable name for the temperature of a Material Stream.
1. Open the Property View of the stream.
2. Go to the Customize ribbon and click on Script Manager (in V12.1, the Script Manager is under the Customize menu).
3. Go to the Directory where you want to record the script.
4. Enter a script name.
5. Click “Record”.
6. Interact with the value (change the temperature to 250 C, for example)
7. Go back to the Script Manager and click on “Stop Recording.”
8. Open the script in a text editor, such as the notepad.
The script line in this file should look something like this:
Specify FlowSht.1/StreamObject.400(5) :Temperature.502.0 2.500000000000e+002
Specify is the action you performed (specified the temperature value).
Next, is the attachment path to the object. In this example (“FlowSht.1/StreamObject.400(5)”), the object is the stream 5 inside Flowsheet 1.
The third word is the backdoor name for the variable we were trying to find. In this example, the backdoor variable name for the temperature of stream 5 is “:Temperature.502.0”.
Finally, 2.500000000000e+002 is the value for the variable, in internal units.
