Abstract

A method of carbon dioxide separation and recovery that can separate and recover carbon dioxide with hydrogen sulfide and carbonyl sulfide removed from a feed gas containing carbon dioxide, hydrogen sulfide, and carbonyl sulfide. This method of carbon dioxide separation and recovery from a feed gas G01 containing carbon dioxide, hydrogen sulfide, and carbonyl sulfide by pressure swing adsorption includes a dehumidification process of removing moisture from the feed gas G01 to produce a dehumidified feed gas, and a carbon dioxide recovery process of separating and recovering carbon dioxide gas from the dehumidified feed gas by pressure swing adsorption. The method also includes a carbonyl sulfide hydrolysis process of reacting carbonyl sulfide with moisture to hydrolyze into hydrogen sulfide and carbon dioxide, and a desulfurization process of separating the hydrogen sulfide.
