Abstract:
TSA method for purification by means of adsorption of a synthetic gas including hydrogen, CO and/or methane, implementing at least one adsorber having at least one adsorbent and subjected to a pressure cycle comprising at least an adsorption step, a step of producing a flow enriched with a main component and a regeneration step, characterized in that the regeneration step includes: regenerating the adsorbent using a regeneration gas including more than 95 mol of nitrogen; and scavenging the adsorbent using a scavenging gas corresponding to a fraction of the synthetic gas to be purified or a fraction of the purified synthetic gas.
