ABSTRACT:
A method of treating gas, such as flue gas, is provided. Flue gas is received into a vessel. The flue gas in the vessel is cooled by at least 17 degrees F. to a temperature of 120 F or lower. Also in the vessel, SOxcompounds are removed such that the concentration of SOxremaining in the flue gas is between 0 ppmv and 10 ppmv. After the flue gas is cooler and SOxcompounds are removed in the vessel, the flue gas is transmitted to a flue gas carbon dioxide scrubbing unit.
