1. A steady state cyclic process for purifying a mixed component fluid stream, comprising:
receiving a feed stream comprising at least a first component and a second component, such that the feed stream flows in a first direction relative to a contactor structure and contacts a chemically active material on or incorporated in the contactor to sorb at least a portion of said second component by chemisorption to provide a first product stream depleted in said second component relative to said feed stream; and
receiving a regenerative stream comprising at least a third component, such that the regenerative stream flows in a second direction relative to the contactor structure generally opposite to said first direction and contacts and chemically interacts with the active material to sorb at least a portion of said third component by chemisorption and to displace at least a portion of said second component to provide an exhaust stream enriched in said second component relative to said first component and regenerative stream; further comprising recirculating and receiving at least some of said first product stream such that the first product stream flows in said first direction relative to the contactor structure and interacts with the active material to desorb and displace from the chemically active material at least a portion of said third component to regenerate the contactor structure for a subsequent cycle and provide a second product stream, comprising the first component of the first product stream diluted in the third component from the regenerative stream, wherein the first component of the second product stream is concentrated by cooling and condensing the third component.
