Abstract
A process and equipment for removing carbon dioxide from a process gas (G), with a solid adsorbent and temperature swing adsorption, where the carbon dioxide is removed from process gas in either a first bed (B1) or a second bed (B2) of adsorbent, while the other bed is regenerated with heat furnished by the incoming hot process gas; the beds are contained in vessels (V1, V2) with heat exchange tubes or plates (T1, T2), so that the removal of CO2 takes place by contacting the process gas with the bed in the shell side, and regeneration of a bed takes place by passing the hot process gas inside the tubes.
