Overview

To run Aspen PLUS OLI the user must first generate an OLI Chemistry Model external to Aspen PLUS. OLI provides two tools for this purpose; the OLI Chemistry Model Generator (which is similar to the ESP chemistry model generator) and the OLI Chemistry Wizard. Both programs perform the same task and are modified from the standard OLI programs to work with Aspen PLUS.

The end result of both OLI programs is the creation of an Aspen PLUS "BKP" file which contains the chemistry paragraph and the chemistry ID for the OLI chemistry model. Also created is the OLI Chemistry Model File which is also known as the "DBS" file. Both the BKP and DBS files must reside in the same folder for Aspen PLUS OLI to operate properly.

We have prepared a video which will show the overall steps in creating and running a simple Aspen PLUS OLI case using Aspen PLUS 7.1 (but the concepts are the same for earlier versions of Aspen).

A written guide with more examples of using Aspen PLUS OLI has also been prepared. This guide was prepared with Aspen PLUS 2006.5.
