Abstract
Hydrogen can be recovered in a refinery network using a combination of a cycling adsorber unit and a membrane separation unit. A membrane separation unit can be used to generate at least a portion of the purge hydrogen stream for the cycling adsorber unit. This can reduce the portion of the hydrogen product stream from the cycling adsorber unit required for regeneration of the adsorbent.
