Abstract
The technical field of the invention is COcapture and sequestration, as well as gas separation and purification technologies. In an aspect is a process for capturing purified COfrom a CO-containing gas, comprising steps: (a) contacting in an absorber column the CO-containing gas with an absorption solution comprising water, ammonia, and potassium carbonate, to enable adsorption of CO, thereby producing a CO-depleted gas and a CO-rich solution; and (b) subjecting the CO-rich solution to desorption conditions in a regeneration column producing a purified COgas stream and a CO-depleted solution.
