PROCEDE DE TRAITEMENT D'UN GAZ PAR ABSORPTION ET INSTALLATION CORRESPONDANTE

摘要

The invention concerns a method which consists in using only two adsorbers which follow each a phase-shifted cycle successively consisting in an adsorption phase, at high pressure of the cycle, and a regeneration phase, ending in repressurizing of the adsorber. The method comprises a step which consists in paralleling the adsorbers in adsorption phase for a predetermined time interval much longer than the switching time of the valves controlling the adsorbers starting said step and/or as long as the difference in temperature between that of a total flux and that of a first flow rate is greater than a predetermined threshold temperature. The invention is applicable to air purification before distillation.
