Continuing Innovations in Acid Gas Cleaning Modeling

The Acid Gas Cleaning functionality was introduced in the Aspen HYSYS V8.3 release and has been continually improved. In addition to amine solvent modeling for gas-liquid systems, you can model Acid Gas removal using physical solvent (DEPG) in V8.6 and Liquid Treating for Acid Gas extraction from NGLs and LNG in V9.

Easily switch from Property Packages from DBR Amine to Aspen HYSYS Acid Gas

In V8.8, you have an option to convert an Aspen HYSYS case which includes a DBR Amines fluid package or an Amines Pkg fluid package to the new Acid Gas package for gas treating. The old case is saved as a backup and a report is produced, with any warnings or errors that occurred.
