Energy efficiency of membrane vs hybrid membrane/cryogenic processes for propane recovery from nitrogen purging vents: A simulation study.

The paper reports on a study of a hybrid process to recover, during flushing by nitrogen, propane contained in pipelines or storage tankers: a standard cryogenic process, but energy-expensive, is coupled to a membrane process. Rigorous process simulations are performed in Aspen Plus® using MEMSIC, a CAPE-OPEN Unit Operation developed at LRGP as a membrane module model. Membrane modules are not often found in libraries of unit operations provided with process simulators. MEMSIC fills this gap.
