Abstract: A fossil fuel fired power plant exhaust gas clean-up and recovery system is provided to remove detrimental compounds/elements from the exhaust gas emitting from the power plant to protect the environment and to recover useful products from the cleaning solution. This is accomplished by directing the exhaust gas from the fossil fuel fired power plant through a single wet scrubber having a cleaning solution of a predetermined pH. The cleaning solution is composed of calcium carbonate and water. A recovery process is attached thereto to reclaim calcium carbonate, calcium sulfate, and carbon dioxide for reuse in the process and/or for commercial use.

Abstract: Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste, human waste, or another bio-solid.

Abstract: A flue gas desulfurization process in which a SO2-containing flue gas stream is contacted with a recirculating stream of an aqueous medium containing concentrated sulfuric acid and hydrogen peroxide, to yield a desulfurized flue gas stream and to produce additional sulfuric acid in the aqueous medium. A portion of the recirculating aqueous sulfuric acid stream is diverted for recovery of the additional sulfuric acid as gypsum in a neutralization step, and the process parameters are adjusted so that the heat of reaction generated during the neutralization step is sufficient to evaporate the free water that is present and yield a gypsum product that is substantially dry.

Abstract: A gas refining method for adsorbing a reducing gas obtained by pressure gasification of coal or oil comprises introducing a reducing gas stream into an adsorbing and removing zone where it contacts an adsorbent. Sulfur-containing compounds are adsorbed onto the adsorbent and a first oxygen-containing gas stream is introduced into the adsorbing and removing zone in order to form a regeneration gas containing sulfur dioxide. The regeneration gas is contacted with a second oxygen-containing stream and a calcium-containing liquid slurry to effect absorption of sulfur dioxide by the slurry and precipitation of a gypsum compound. The temperature of the slurry is varied to cause selective precipitation of 60 -gypsum hemihydrate or gypsum dihydrate.

Abstract: A system for removing SO.sub.2, NO.sub.2, and other contaminants from flue gases uses hydrogen peroxide (H.sub.2 O.sub.2) as the reagent to convert the oxides of sulfur and some of the oxides of nitrogen (NO, NO.sub.2, etc.) to more stable oxidation states. Acids formed as a result of this conversion, namely sulfuric acid (H.sub.2 SO.sub.4) and nitric acid (HNO.sub.3) can then be neutralized with limestone or, alternatively, the sulfuric and nitric acids can be collected and processed for sale as an industrial product.

Abstract: A wet flue-gas desulfurization system which effectively reduces the mist concentration in the treated gas at its outlet. The system includes an absorption column, formed with a tank at the bottom which is supplied with an absorbent slurry and a circulating pump for forcing the slurry upwardly from the tank into the flue gas inlet at the top of the column for contact with flue gas. Sulfur dioxide, for example, is removed from the flue gas, being introduced in the flue gas inlet, by absorption with the absorbent slurry. The treated gas, free of sulfur dioxide, is discharged through a gas-outlet duct formed to rise integrally from the top of an end part of the tank. For reducing the mist concentration a mist eliminator is provided and is held upright, as a vertical partition, across the riser of the duct, with the lower end of the eliminator being extended partly into the bath of the absorbent slurry inside the tank.

Abstract: A flue-gas scrubbing-liquor regeneration process that is based on contacting N-S compounds contained in a flue-gas scrubbing liquor with a lime/limestone solution in a double draw-off crystallizer under suitable pH conditions for precipitating calcium salts of N-S compounds. The precipitated crop is filtered and then hydrolyzed in a sulfuric acid environment to produce gypsum and ammonium sulfate in solution. The hydrolyzed slurry is filtered and the filtrate is neutralized with lime to liberate ammonia gas that is then sparged through a sulfuric acid solution to cause the precipitation of commercial-grade ammonium sulfate.
