Previous work from this group has utilized a HYSYS simulator to predict the performance of an ethylene oxidative dehydrogenation (ODH) production facility using alternative diluents and separation technology not currently used in the standard industrial process. This work has investigated the development of membrane-based separation technology for the production of ethylene for the oxidative dehydrogenation (ODH) reaction of ethane using a HYSYS simulator with MEMCAL extension software in concert with kinetic reaction data for the M1 catalyst, flammability safety determinations and economic analysis. The application of polymer-membrane separation and non-cryogenic distillation alternatives, such as bottom-flash, heat-pump assisted and low-temperature distillation, were simulated and evaluated individually and in-tandem with membrane separation. The effects of ODH reaction kinetics, alternative diluents, process flammability issues, and economic analysis results will be discussed.
