ABSTRACT:
The present invention involves a process for recovering hydrogen from a feed gas mixture comprising hydrogen and at least one other component. The feed gas mixture is initially separated in a membrane separation unit to produce a hydrogen-rich stream and a hydrogen-lean stream. The hydrogen-lean stream is subsequently treated in a cryogenic separation unit to remove a portion of the non-hydrogen components and produce a hydrogen-enriched stream. The hydrogen-enriched stream from the cryogenic separation unit is recycled and combined with the feed gas mixture to the membrane separation unit.
