Problem Statement: When opening an .apw file, Aspen Plus gets the components mixed up (i.e., it starts to use physical property parameters for the wrong components). If an .inp file is exported, I get this for components:
COMPONENTS

ETHANOL C6H12O-E1 /
PROPANOL C5H8O-D1 /
WATER C5H4O2 /
P-XYLENE C8H10-... | Solution: This problem occurs when an old .apw file is used after the user interface has been customized to add a user or inhouse databank. When the user interface is customized, the system definition file (recdef) will change. The recdef contains pointers to the components which will point to new places after the cust... |

Problem Statement: Aspen Plus V8.4 now thinks that Equation Oriented (EO) input is incomplete if the physical type is not specified. Earlier versions accepted EO Input without a physical type. | Solution: Starting in V8.4, the EO Input form now requires physical type and units to be specified for each variable. This ensures that the value and bounds specifications are interpreted correctly if the global unit set is changed. It was always possible to specify these units, but it was not required, so simulations ... |
Problem Statement: Files with the .scr extension which Windows 7 takes to be screensaver files are impossible to delete. Therefore, if Aspen Plus crashes, I'm left with a file I can't delete. In addition, a file FORT.32 has been created in the local working directory. | Solution: The inability to delete a .scr file (this is the accounting file unit 32) is caused by use of anti-virus software for Windows, McAfee VirusScan Enterprise. Apparently the software tries to protect the system registry by preventing the user (even an administrator) from moving or deleting a .scr file. Temporar... |
Problem Statement: Is it possible to specify the reaction in the condenser and reflux drum?  | Solution: Reactions in the reflux drum and condenser cannot be modeled in Aspen Batch Modeler.
This is not as clear as you might expect when selecting option "reaction occur in all stages" that condenser and the reflux drum (if available in the column) will be also taken into account.
When specifying in the simulation ... |

Problem Statement: Why do I receive the error:
"Export error: The maximum number of columns in an excel worksheet with the current format is 256"
Is there a workaround? | Solution: In Aspen Flare System Analyzer (AFSA), when you run into this 256 columns limit issue, most likely you have too many fittings inside a pipe or too many components. Older versions of Excel used to have the limit of 256 columns. Consequently, lots of components, like the Infragistics that AFSA uses to write to ... |

Problem Statement: The "Default" value of the PIPESIM registry key is a version of PIPESIM that is installed (e.g. 2010.1 or 2011.1), and that value is a subkey to the PIPESIM registry key. When Aspen HYSYS fails to find the subkey for the version written to "(Default)" it issues an error message and fails. | Solution: The key should be under either HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER (depending on if the program was installed "for all users" or "current user" option on the computer). The location is Software\Schlumberger\PIPESIM. The subkeys to this key should be the versions of PIPESIM installed, and the "Default" va... |

Problem Statement: How to get rid of below error message while performing Knock-Out drum calculations?
"Not enough data is there to calculate design. Please solve the Rating at least once with the option of saving phase properties" | Solution: Sizing calculations of knockout drum are function of the flow rate upstream of the drum, conditions in the drum (P, T and vapor fraction) and physical properties of the fluid. So before calculating the diameter, you must make sure that phase properties are calculated. Otherwise the above error message will ap... |
Problem Statement: What could cause the error, 'Unable to Load Simulation Case' when an Aspen Plus or Aspen HYSYS file is being imported in Aspen Flare System Analyzer? | Solution: In some cases, when importing Aspen Plus file using the Import Sources/Aspen Plus/HYSYS Relief Valve Sources (as shown below) in Aspen Flare System Analyzer (AFSA or Flarenet) an error will be detected 'Unable to Load Simulation Case'.
One of the reasons could be that the Aspen Plus/HYSYS cases contains the c... |
Problem Statement: After exporting Tray Sizing results to "*.sulcol" file in Aspen HYSYS, why I cannot open this file using SulCol v3.2? | Solution: This is due to a version issue between the exported file from Aspen HYSYS and the current SulCol software. The "*.sulcol" file generated from Aspen HYSYS is currently a lower version (version 2). Between Sulcol v2 and v3, major changes have been done in Sulzer, therefore the file cannot be opened directly fro... |
Problem Statement: How to find the wall temperature of a pipe segment. | Solution: Unfortunately there is no way to see these variables in the Aspen HYSYS pipe segment.

Problem Statement: In the model we apply some bias to some properties (eg. RON). These properties are correctly calculated in the final blend, but when looking at the UBML derived properties (eg. RONE, RON with ethanol) the bias doesn't affect the calculation of the derived property in the final blend. | Solution: As UBML derived properties are very complex, it is highly probable that the property calculation of the blend comes from the components (eg. RON from component 1, RON from component 2,...). The value of bias is applied to the heel, so it will only affect the final blend. As the properties of the final blend a... |
Problem Statement: How do you define the effect of temperature contribution and user supplied DT Contribution overwriting Global dTmin values? | Solution: The Global contribution is defined as (+/-)dTMin/2 for Cold (+)/Hot(-) streams.

Problem Statement: When using the PIPE model and another program, very different K factor losses are calculated. For what K factors are Aspen Plus calculating in each section of a pipe? | Solution: Aspen Plus doesn't calculate a loss K factor for the pipe length. Aspen Plus integrates down the length of the pipe to calculate the pressure drop.
For most of the fittings, (gate valves, butterfly valves, Large 90 degree elbows, Straight tees, Branched tees) we do not calculate a K-Value in Aspen Plus. The... |
