We need a list of parameters passed from the OLI engine to Aspen Plus. For example we calculate viscosity but suspect that Aspen PLUS is not using our values.  We should have a published list of what we send back.

SCTD   - Solid Scaling Tendency
SLMX   - Liquid entropy
SIGM   - Liquid surface tension
PHL    - pH and pOH
PHIVMX -  Fugacity Coeff Component Vapor PHILMX - Fugacity Coeff Component Liquid
PHIL   - Pure compound figacity coefficient
VISG   - Vapor viscosity
VISL   - LIQUID MIXTURE VISCOSITY
THKG   - Vapor thermal conductivity
THKL   - Liquid thermal conductivity

3716 14176

When a user was trying to work with the cwa file with OLI Engine for Aspen 9.2.6 Build, the solids were originally off. When the solids where then turned on , the screen on the right to the solids, was not populated with the Solids list. When the user went one screen back and clicked Next again, the solids were now visible.

Solids button needs to be on while generating the model, solids list not generated interactively
.


Solid list is now populated regardless of solid phase state

The standard Help>About information is missing from the Chemistry Generator. This makes it hard to determine what build is being used.

Updated 'About OLI Software' dialogue to accept/change security.

Chemistry wizard fails with a Aspen ID for a name that is too long.  Seems to use the same name twice.

Updated to use Aspen solid id with the '-S' removed for components that have no entry in the GENERAL section. If no solid tag exists we truncate OLI Tag to 8 characters.

Bug ID OLI Case Description Reported by Resolved By

A solver error occurs because the ASNM record for FEIIICL2ION in the MSEPUB dabank is FECL2+2

It should be FECL2+

Tested in 9.2.1 and this issue has been resolved for both MSE and PUBLIC.

OLI CD

ASID and ASNM records ignored in MSEPUB if a private databank is used

Tested in 9.2.1 and this issue has been resolved.

OLI Config tool for Aspen Plus 9.2 did not detect Aspen Plus 8.6 after the update .

There was an error in the XML reader that was removing spaces within a string, this was only happening when a space with a string landed on a 512 byte boundary.

Liq Thermal Conducitvioty values reported in MSE were too large by 1000 times

OLI was returning the thermal conductivity values in cal/(Hr*m*C) while Aspen PLUS was expecting Watt/(m*C). OLI changed the unit set to be consistent with Aspen PLUS (PK)

1.0.1 General Release

Solver updated to ESP 8.0.60 standards

General release of Alliance Suite to match updated Aspen Plus. Includes all database updates as of ESP 7.0.53

New version under development by Aspen Technologies. OLI has updated its interface to match

  • EFRACH columns have a test to see that the overhead stream is truly a liquid when set as a decanted liquid. If an error occurs, the error is ignored

1.0.2

General Release

  1. A unused property by OLI was now causing a dvivide be zero error in the array RETN(STWORK_KFOUT). OLI now populates this array so Aspen Plus does not trip the error message. This value is not used by OLI.
  2. An error message was reported to the history file (but not model manager). "Error: Failed in RefProp termination process". This is a new feature added by Aspen Plus of which OLI is unaware. The error occured only on the Aspen side and is fixed in the latest release of Aspen
  3. Databanks were updated to ESP 8.0.58
04.22.2008
2006 1.0.4 General Release
  1. The Chemistry Generator and Chemistry Wizard were updated to accept databases created with ESP build 7.0.49 or later. Previous build of the alliance product were limited to databases created with ESP version 7.0.48 or earlier.
  2. The database was updated to the current ESP databases. See Current Database Versions
02.21.2008
2006 1.0.3 General Release
  1. The OLI Chemistry Wizard was developed to support the OLI/MSE programs (outside of Aspen Plus). This inadvertantly introduced two new parameters that the existing Aspen OLI solver did not understand resulting in a crash in Aspen. This only affected Aspen OLI/MSE cases (rare). The solver has been updated to account for the extra parameters the Chemistry Wizard was used. Models generated with the traditional ESP-Like interface are unaffected.
  2. The Aspen OLI solver was updated to OLI version 7.0.48 standards. The PUBLIC and MSEPUB databases were also updated to 7.0.48. Changes in the enthalpy extrapolations above 300 C were modified.
  3. The user added OLI unit operations were not working. They needed to be rebuilt for AspenOne They have been rebuilt and are now available for use. These unit operations are automatically installed and may be access via the Menu Item: Library > References
