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. For more information about EC-OD please contact firstname.lastname@example.org or email@example.com.
The utility integrates with Aspen HYSYS and aids in the 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.
