ABSTRACT:
A feed gas stream is separated by the use of one or more permeable membranes for bulk separation and for residual product gas recovery, in combination with a pressure swing adsorption process for the recovery of high purity product gas, e.g., hydrogen from mixtures thereof with methane. Waste gas from the PSA system is passed to one or more of such permeable membranes for enhanced product recovery, the recovery levels achieved being advantageously reconciled with the corresponding compression and other cost factors pertaining to the overall process for the production of such high purity product gas.
