| abstract | In flue gas desulfurization and the like, the gas is pretreated to remove sulfur trioxide and sulfuric acid by first cooling the gas, for example, from about 250 ° F to 400 ° F, in a combustion air preheater (14), and then simultaneously or after the introduction of an aqueous stream (18) from an FGD system (20) (destruction of smoke gases) containing dissolved chloride, said chloride aqueous stream (18) being completely vaporized upon injection (22) into said gas, and recovering from the gas chloride salts which remain in the gas after the fraction of water in the aqueous stream has been vaporized, and chloride of ammonium which precipitates on the fly ash in the gas, or forms a finely divided suspension. Ammonia can be added (16) to react with at least some of the Cl- compounds contained in the flue gas if further reduction of the chloride in the FGD system (20) is desired. |
