ABSTRACT:
Reduction in energy consumption is had in a system for adsorptive removal of moisture and CO.sub.2 from atmospheric air by passing the feed air through consecutive beds of adsorbent comprising first alumina then molecular sieve zeolite, at near ambient temperature during adsorption of these impurities and subsequent regeneration of the sorbent laden beds by pressure reduction to about atmospheric level and purge at that level with product gas freed of water and CO.sub.2.
