ABSTRACT:
An integrated pressure swing adsorption/membrane separation process is disclosed for the separation and purification of at least one gas component of a feed gas in which the purge effluent from the pressure swing adsorption part of the system is passed through a membrane separation unit to produce a non-permeate which is utilized as a displacement gas in the pressure swing adsorption part of the system. Desirably, the permeate is also utilized as a purge gas or repressurization gas. The apparatus for carrying out the process is also disclosed.
