ABSTRACT:
Complementary pressure swing adsorption is a method of purifying and quantitatively recovering a plurality of components from a multicomponent gaseous mixture. A plurality of adsorption columns is used, each containing an adsorbent which is selective for one of the components to be recovered, but not the others. Blowdown and purge effluent from each column is used as high-pressure feed for a complementary column containing a different adsorbent. Nitrogen and oxygen may be separated from air, for use on tactical aircraft or in hospitals and various industries.
