Abstract
A pressure swing adsorption process is set forth for the recovery of two gas products at high recovery and high purity using the steps of adsorption, depressurization, low pressure purge, evacuation and repressurization. The purge effluent and a portion of the depressurization effluent are used to partially accomplish the repressurization step.
