    摘要： A wet scrubbing process for removing sulfur dioxide from combustion gases uses an aqueous slurry containing calcium components resulting from the slaking of lime, with the slaked lime formed by mixing lime with water containing a calcium sulfur-oxide salt. The presence of the calcium sulfur oxide salt in the slaking water results in a more easily dewatered sludge that is subsequently removed from the wet scrubbing system.

    摘要： A method for removing sulfur dioxide from flue gases in a wet scrubbing system where calcium thiosulfate and calcium polysulfides are formed by the reaction of lime and emulsified sulfur and the mixture added to a recycle tank of the wet scrubber where it reacts with sulfites and bisulfites in the scrubbing slurry to produce thiosulfates from the calcium polysulfides, with the slurry then returned to the scrubber. The mixture of calcium thiosulfate and calcium polysulfides may be formed in the lime slaking tank or lime storage tank of a lime scrubbing system or formed in a mixing tank and added to a lime or limestone scrubbing system.

    摘要： Sulfur dioxide is removed from flue gases using an aqueous solution of magnesium components in a wet scrubber, with oxidation of a portion of the aqueous discharge from the scrubber. Calcium sulfate is added to the portion of aqueous discharge at the oxidizer to form an oxidized aqueous effluent containing calcium sulfate solids and dissolved magnesium sulfate. The oxidized aqueous effluent is regenerated by addition of lime, in a regeneration tank, which precipitates calcium sulfate as gypsum, with gypsum returned to the oxidizer as the calcium sulfate added thereto. Preferably, the aqueous discharge from the scrubber is divided, with a major portion passed to a separator to remove gypsum, therefrom, while a minor portion is passed to the regeneration tank. Magnesium sulfate solution, after separation of gypsum from the major portion may also be fed to the regeneration tank.

    摘要： A boosted no-lance injection system (BNLS) and methods of operating a combustion system to reduce acid gas or metal emissions in the flue gas is shown and described. In one embodiment, a BNLS includes an injection device, a high volumetric flow air mover, a transport air mover, a sorbent hopper and a mounting apparatus. In other embodiments, a method of operating a combustion system includes positioning the BNLS to inject into the ductwork, applying transport air and sorbent into the ductwork, and applying the high volumetric flow air into the ductwork. The result is methods and systems for reducing acid or metal emissions in the flue gas.

    摘要： 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.

    摘要： A desulfurization process using magnesium sulfites in a clear solution has the discharge from a wet scrubbing unit passed to a reaction tank. A silica-containing solid particulate material, such as sand, is added to the reaction tank and lime is added to precipitate calcium sulfite solids onto the particulate material. The resulting solids, a calcium sulfite coated, silica containing solid particulate material is readily dewatered and may be used as a cement manufacturing process.
