  • Method of fractionation of a gaseous mixture by adsorption
    Patent number: 4042349
    Abstract: An improved method of fractionation of a gaseous mixture by adsorption, in which the efficiency of extraction and the content of the desired constituent in the gaseous fraction extracted are increased, the method utilizing two or more adsorption lines, each including at least one adsorber comprising an adsorbent mass which preferentially adsorbs at least one constituent of the gaseous mixture, the first adsorption line comprising:A constant-pressure extraction stage, during which the gaseous mixture is introduced into the inlet of said line, circulates from the inlet to the outlet of at least one adsorber in said line in the adsorption direction, at a high pressure in said adsorber, so as to obtain at the outlet of said line a gaseous fraction impoverished in at least one constituent of said gaseous mixture;A regeneration stage comprising a period of falling pressure, during which the outlet of the adsorption line is closed and there is extracted at the inlet of said line a gaseous fraction enriched in at lea
