Abstract
A process of using solutions containing thiosulfate and/or chloride salt reagents to remove SOand HSOacid gases from a flue gas. The solution is injected into a moving volume of flue gas to achieve a droplet size that enables the solution to dry on contact with the flue gas, generating dried particles of the reagent that react with the SOand HSOacid gases yielding a salt precipitate. SOpresent in the flue gas may also be absorbed with the solution, with a subsequent reaction yielding bisulfite species that, upon drying of the droplet, react with the SOand HSOacid gases to form salts that are removed from the gas. The removal of these acid gases from a flue gas reduce corrosion of equipment used in coal or oil fired power plants downstream of the injection cite.
