Abstract:
1. In an adsorption process for removing water and CO 2 from a feed gas wherein: (a) the process employs an adsorption vessel having a feed port for introducing the feed gas and a product port for withdrawing product gas; (b) located adjacent to feed port is a water removal zone containing a water selective adsorbent for adsorbing the water from the feed gas; (c) located between the water removal zone and the product port is a CO (d) the process cycles between an adsorption sequence and a regeneration sequence; (e) during the adsorption sequence: (f) during the regeneration sequence: (g) the water selective adsorbent contained in the water removal zone consists of ten equally thick layers, with layer the improvement comprising adjusting the quantity of regeneration heat as a function of temperature data taken within a strategic portion of the water selective adsorbent zone comprising any 3-4 consecutive layers between (and including) layers 2 through 9 .
