How to use vacuum pump for gas only in HYSYS?

16 October 2018 1 6K Report

Hi All, Can we use vacuum pump for dry gas only where inlet pressure higher (> 1 bar) and outlet is less than 1 bar in HYSYS? Purpose is to create pressure ratio cross the membrane for CO2/CH4 separation by vacuum pump.

Thank you.
