ABSTRACT:
Described is an improved pressure-swing adsorption process and apparatus which enable more thorough regeneration and, thus, a higher yield of one or more selected gases and a higher productivity of the adsorbent material. The pressure-swing adsorption process and apparatus for obtaining a selected gas are of the type wherein a PSA product gas is obtained by the steps of pressurizing, producing, purging and venting a vessel that contains an adsorbent for a gas other than the selected gas. The improvement is a step of purging the adsorbent with a purge gas that has a higher concentration of the selected gas than the PSA product gas.
