Abstract
A process and system for improving the efficiency of regenerating a CO-rich liquid absorbent stream following contact in an absorption zone with, e.g., a flue gas stream from which it has absorbed CO, and recovering a substantially pure stream of includes passing the pressurized liquid sorbent through a heating zone to heat it to the desorption temperature, e.g., to about 80°-85° C. for aqueous KCOsorbent, introducing the heated liquid sorbent into a cyclone separation zone where the combination of increased temperature, reduced pressure and the centrifugal forces on the liquid/gas mixture result in a relatively more rapid and efficient separation of the COfrom the liquid sorbent from which it has been released. The CO-lean liquid sorbent descends to the bottom of the cyclone separator and is recovered, cooled and recycled to the absorption zone; the COwithdrawn from the cyclone separation zone passes through a condenser to remove moisture and any other condensates present, and the COis recovered for storage or use in downstream processes.
