Abstract:
Process for the complete separation of an adsorbable gas component A from another substantially non-adsorbable gas component B in at least two adsorption zones 1 and 2 arranged one behind the other, comprising the following steps: A. IN THE FIRST STEP THE ADSORPTION ZONE 1 IS LOADED UNTIL COMPLETELY SATURATED WITH THE COMPONENT A; b. in the second step the feed gas in the interstitial volume of adsorption zone 1 is displaced with pure component A from a storage means and the sweeping gas, optionally together with the feed gas is delivered to the partially unloaded zone 2; C. IN THE THIRD STEP THE PURE COMPONENT A is liberated by heating of zone 1 and is delivered to a storage means. Thereafter the aforesaid steps are repeated however with interchanged functions of zones 1 and 2.
