The process involves (a) contacting a flue gas stream containing water vapor and COwith an ionic absorbent under absorption conditions to absorb at least a portion of the COfrom the flue gas stream and form a CO-absorbent complex; wherein the ionic absorbent comprises a cation and an anion comprising an amine moiety; and (b) recovering a gaseous product having a reduced COcontent.
