ABSTRACT:
A method and apparatus is disclosed in the separation of a gaseous mixture by pressure swing adsorption utilizing two beds of adsorptive material which are operated out of phase in the cycle thereby providing a more-or-less continuous flow of product. Each adsorbent bed contains a heat exchange chamber holding a volatile liquid. The liquid gives up vapor in the bed undergoing adsorption and condenses in the bed undergoing desorption. Heat is thereby transferred between the beds, thus improving the efficiency of each stage by retaining heat which would otherwise be lost.
