CARBON DIOXIDE SCRUBBING WITH AMMONIUM CARBONATE AND AMMONIA VAPOR CONTROL

摘要

A method for removing carbon dioxide from a gas stream and controlling ammonia vapor by scrubbing the carbon dioxide from the gas stream with ammonium carbonate, thereby producing ammonia vapor and ammonium bicarbonate; removing a portion of the ammonia vapor from the gas stream with ammonium bicarbonate; and polishing the flue gas to achieve an ammonia concentration of less than 10 PPM.
