More Information
Summary:This method for separating and recovering carbon dioxide includes: a step for bringing a particulate carbon dioxide adsorbent into contact with a carbon dioxide-containing gas to be treated, and adsorbing carbon dioxide contained in the gas to be treated onto the carbon dioxide adsorbent; and a step for regenerating the carbon dioxide adsorbent and recovering desorbed carbon dioxide, by bringing a carbon dioxide adsorbent in which carbon dioxide is adsorbed, into contact with desorption vapor, to desorb carbon dioxide from the carbon dioxide adsorbent. The step for recovering carbon dioxide includes using, as a heat source of the heat exchanger, the recovered gas which contains: desorption vapor which has contacted the carbon dioxide adsorbent; and carbon dioxide which has been desorbed from the carbon dioxide adsorbent.
