A PROCESS AND APPARATUS FOR SEPARATING THE COMPONENTS OF A GAS MIXTURE IN A PAIR OF ADSORPTION VESSELS (A,B) USING A SINGLE GAS COMPRESSOR/PUMP (P) TO MOVE GAS INTO AND OUT OF THE ADSORPTION VESSELS(A,B). THE CYCLE IS SUCH THAT THE GAS COMPRESSOR/PUMP(P) IS IN CONTINUOUS OPERATION. THE ADSORPTION CYCLE IS NON-SYMMETRICAL IN THAT THE SERIES OF STEPS CARRIED OUT IN ONE OF THE ADSORBERS IS NOT THE SAME AS THE SERIES OF STEPS CARRIED OUT IN THE OTHER ADSORBER. THE APPARATUS INCLUDES AN INTERMEDIATE GAS STORAGE CONTAINER(C) WHICH IS USED TO TEMPORARILY STORE GAS REMOVED FROM THE NONADSORBED GAS OUTLET END(24,26) OF THE ADSORPTION VESSELS (A,B) SO THAT IT CAN BE USED TO PARTIALLY PRESSURIZE THE ADSORPTION VESSELS UPON COMPLETION OF THE ADSORBENT REGENERATION STEP OF THE ADSORPTION CYCLE.FIG.1
