Simulation study compares ethane recovery in turboexpander processes

A simulation study of five ethane-recovery processes showed that significantly higher ethane recovery results in turboexpander processes that have a gas-liquid and gas-gas exchanger and use the gas to provide required bottom reboiler duty. The study shows that adding a reflux stream significantly decreases ethane recovery; including a cold liquid exchanger or a second expansion stage yields nearly the same ethane recovery results.Results show, therefore, that additional complexity in the design of ethane recovery plants is not necessarily useful and may lead to either lower or insignificant additional ethane recovery.C2+ recovery provides ethane, a valuable petrochemical feedstock, in add...
