OLI Corrosion Analyzer Plug-in now enabled.

There is one known issue: When saving the Corrosion Analyzer results, you are required to save both the Unisim Design document and the open Corrosion Analyzer document. Saving the OLI Corrosion Analyzer document only saved the memory space inside the Unisim Design document.

After launching the OLI Corrosion Analyzer Plug-in and then Exiting Unisim Design, the Unisim design program stays in memory and is an active process.

This version is linked to the ESP v7.0.38 database. The mixed solvent electrolyte model is also enabled.

This was an internal release.

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

Under Development

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

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

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

This version is linked to the OLI/Engine version 7.0.40 and to the OLI Databases for 7.0.40. The Mixed Solvent Electrolyte option is not available in this release:
