ABSTRACT:
A treatment process for a hydrogen-containing off-gas stream from a refinery, petrochemical plant or the like. The process includes three separation steps: condensation, membrane separation and hydrocarbon fraction separation. The membrane separation step is characterized in that it is carried out using a polymeric separation membrane that is selective in favor of hydrocarbons, including methane, over hydrogen, so that the hydrogen-enriched stream is delivered at high pressure.
