Abstract

"Process for recovering a gas or vapor from a gas mixture", comprising continuously flowing the mixture in contact with adsorbent granules (gas or liquid) circulating through an adsorption zone in counter-current with the mixture, in such a way that a practically fixed gradient of increasing gas or liquid content in the granules is established in the zone; removing the granules from the adsorption zone and introducing them continuously in a desorption zone, through which the granules circulate countercurrently with a hot and gaseous desorbent, the gas or liquid is desorbed and eliminated from the zone with the desorbent , and under such conditions that within the desorption zone a practically fixed gradient of decreasing content of gas or liquid is established in the granules, characterized in that a part, preferably 50 to 80% of the granules passing through the tower of desorption is continuously withdrawn as a secondary stream and introduced into a region of the adsorption zone, in which the granules that therein contain an analogous proportion of gas or liquid adsorbed.
