More particularly, the model was a dynamic simulation built in HYSYS™ v7.1. The component slate was simplified and selected to give a vapor and two liquid phases, and have the ability to measure an S/B ratio. All the unit operations were included and modeled as best fit within HYSYS™. Pumps were all ...
