Zusammenfassung:The quantity of heat to be provided by a regeneration gas in an adsorption process that removes water and carbon dioxide from a feed gas using a hybrid of both temperature swing (TSA) and pressure swing (PSA) to regenerate the adsorbent is adjusted as a function of temperature data taken within a "strategic portion" of the water selective adsorbent zone. The strategic portion corresponds to the location for the desired transition from regeneration by temperature swing to regeneration by pressure swing and, if the water selective adsorbent contained in the water removal zone is notionally considered to consist of ten equally thick layers, comprises any 3 to 4 consecutive internal layers.
