An adsorption process in which high and low pressure feed streams are introduced into a plurality of beds to produce product streams by adsorbing one or more preferentially adsorbed components within the beds. Each bed is subjected to a low pressure feed stage to produce a low pressure product stream followed by a high or higher pressure feeding stages to produce one or more high pressure product streams. Thereafter the beds are regenerated through depressurization and purge stages. The cycle is conducted out of phase so that one of the beds is producing the high pressure product stream while another bed is producing a low pressure product stream.

An adsorption process including: introducing at least high and a low pressure feed streams into a plurality of adsorption beds containing at least one adsorbent to adsorb at least one more preferentially adsorbed component contained within said high and low pressure feed streams, thereby to produce at least high and low pressure product streams from adsorption by said at least one adsorbent; subjecting said plurality of adsorption beds to operational cycles, each having at least two adsorption stages comprising high and low pressure feed stages having said high and low pressure feeds streams introduced into said adsorption beds; at least two repressurization stages situated just prior to said high and low pressure feed stages, said at least two repressurization stages comprising a high pressure repressurization stage prior to said high pressure feed stage and a low pressure repressurization stage before said low pressure feed stage; and regeneration stages for desorbing said at least one more preferentially adsorbed component; and said operational cycles being conducted out-of-phase with respect to one another, such that said high and low pressure product streams are continually being produced.
