Abstract
A method for separating carbon dioxide and water from a gas mixture by cyclic adsorption/desorption, using a unit containing an adsorber structure, comprising the following repeating steps: (a) contacting said mixture with sorbent material; (b) at least one of evacuating said unit and heating said sorbent material and extracting the gaseous carbon dioxide and water vapour and separating gaseous carbon dioxide from water vapour; (c) cooling the adsorber structure and re-pressurisation; wherein (i) in step (c) the heat released is stored in a first heat storage device; (ii) during step (b) the sensible and latent heat of gaseous carbon dioxide and water vapour as product gases is stored in second heat storage device; and (iii) during step (b) the heat required for heating said sorbent material is supplied from heat recovered in at least one of step actions (i) and (ii) of previous sequence(s).
