Abstract

Process of capturing carbon dioxide. Air is scrubbed with a basic solvent, thereby forming a solution comprising bicarbonate anions. This solution is then passed through an anion exchange resin at least partly loaded with hydroxide anions. The anion exchange resin is then desorbed with a solution of an alkali metal salt. CO₂ is released by treating the aqueous bicarbonate solution an acidic solution while forming an solution of an alkali metal salt. This solution is treated by EBDM to regain the alkali metal hydroxide solution and the acid used for the CO₂ release. The desorbed anion exchange resin is regenerated by flushing it with the alkali metal hydroxide solution EDBM.
