OLI Engine with RadFrac and FraChem
Contents
How to enter specifications from FraChem Column to RadFrac Column
When using OLI Engine in Aspen Plus, it is recommended that the end user enables OLI models from Aspen Libraries and use OLI's FraChem column. FraChem and RadFrac perform similar duties as 2-3 phase fractionation for a single column, model absorbers or strippers. When using FraChem it is imperative that you have OLI Chemistry model loaded in Aspen Plus.
