ABSTRACT:
There is disclosed a process and apparatus for gas enrichment utilizing pressure swing adsorption techniques wherein the compressed gaseous mixture being processed is passed in indirect heat transfer relationship to a bed of adsorption material in an adsorption vessel undergoing regeneration wherein the heat of compression is employed to improve regeneration of the bed of adsorption material during the desorption step prior to passing the compressed gaseous mixture through a cooling system and thence through a bed of adsorption material for gas enrichment at a lower, more efficacious adsorption temperature.
