Pressure swing adsorption process and system utilizing two product storage tanks

摘要

Pressure swing adsorption process and system for separating gas mixtures comprising at least one more strongly adsorbable component and at least one less strongly adsorbable component. The process includes storing gas enriched in one of the components in a first storage tank and a second storage tank which are arranged in series. Final product gas is provided from the second storage tank while gas for purge, rinse, and/or repressurization is provided from the first storage tank.
