Abstract: Generally, a cyclic sorptive gas separation process can comprise a feed or sorbing step followed by a regenerating step. In embodiments, the sorbing step can involve admitting said feed stream into a contactor, sorbing at least a portion of a first component onto a sorbent, producing a first product stream, and recovering a first product stream. In embodiments, the regenerating step can comprise admitting or feeding the first regeneration stream into the contactor, sorbing a fraction of a third component onto the contactor, desorbing a fraction of the first component, and recovering a second product stream from the contactor, wherein the regeneration step further comprises controlling a partial pressure of the third component to a partial pressure threshold equal to or greater than 0.4 Bara.
