ABSTRACT:
A trans-atmospheric pressure swing adsorption process is carried out using product gas for purge and partial repressurization in the production of oxygen from air. No transfer of gas is made directly from one bed to another, as for pressure equalization purposes, but the power requirements are reduced under controlled pressure swing conditions.
