Expander/Compressor Off-Design Utility (EC-ODTM) for Aspen HYSYS®

Mafi-Trench and River City Engineering have developed new software used to predict turbo-expander off-design performance in plant simulations. EC-OD is a unit operation extension designed to rigorously calculate expander compressor off-design performance within Aspen HYSYS.

CO2 Freeze Utility for Aspen HYSYS®

The utility integrates with Aspen HYSYS and aids in the rigorous evaluation of CO2 freeze potential for natural gas processing plants. It predicts both vapor and liquid phase CO2 freezing temperatures for process streams, heat exchangers, expanders, and columns. For more information about CO2 Freeze please contact [email protected].
