ABSTRACT:
A process and an apparatus related to the reduction of the level of a component in a feed gas such as air involving passing the gas to at least three parallel thermal swing adsorption zones charged with an adsorbent and operating according to an adsorption cycle, wherein the cycle of each zone is phased with respect to that of the other zones so that at any point during the cycle, the number of zones in the adsorption step is greater than the number of zones not in the adsorption step.
