Abstract
A method for the removal from a feed gas stream such as air of at least two contaminating gas components such as water and CO.sub.2 features repeated cycles of operation the improvement which comprise: feeding a regenerating gas such as dry nitrogen at a higher temperature, e.g. 70.degree. C., in a direction counter-current to the feed direction in contact with the adsorbent to produce a heat pulse travelling in the counter-current direction to desorb the less strongly adsorbed second contaminating gas component from the downstream (with respect to the feed direction) portion of the adsorbent by TSA while at the same time desorbing the more strongly adsorbed second contaminating gas component from the upstream (with respect to the feed direction) portion of the adsorbent by PSA.
