  • Flue gas desulfurization with oxidation of calcium sulfite in FGD discharges
    Patent number: 4976936
    Abstract: A method for removing sulfur dioxide from flue gases, with oxidation of calcium sulfite in the discharge from a liquid scrubbing system to produce gypsum, oxidizes the sulfite in a thickener overflow at a pH of between 4.0 and 6.5. The calcium sulfite is oxidized to a calcium sulfate which precipitates from the aqueous media and is separated, while the acidic aqueous media is recycled to an acidification step preceding the oxidation. A further minor portion of scrubber slurry may be discharged from the liquid scrubber unit at a pH of 4.5 to 6.0 and also treated with acid, oxidized, and the resultant gypsum separated.
