Abstract

Method and apparatus for separating gaseous mixtures using adsorbent material. The mixture is contacted with an adsorbent bed which adsorbs preferentially a desired product gas constituent of the mixture. The bed is then purged with such gas or a stream rich in such gas at a pressure substantially equal to the partial pressure of that gas in the gaseous mixture fed to the adsorbent bed. The bed is then regenerated to recover product gas.
