청구항

In a pressure swing adsorption process for the recovery of either oxygen or nitrogen product in an adsorption system having at least one adsorbent bed containing adsorbent material capable of selectively adsorbing either oxygen or nitrogen as a more readily adsorbable component of feed air, said process comprising, on a cyclic basis in each bed, an adsorption/desorption/repressurization sequence in which a desired product is recovered from the system and a waste stream is discharged from said system, the improvement comprising: (a) separating a portion o...
