摘要： An apparatus (10) and process for removing acidic gases and NOx from flue gases produced by utility and industrial plants. The process and apparatus (10) convert NOx, and particularly nitric oxide, to nitrogen dioxide, which is then reacted to form a valuable byproduct. The process generally entails contacting a flue gas with a scrubbing medium (14) to absorb acidic gases from flue gas and produce an intermediate flue gas. The intermediate flue gas is then cooled to cause nitric oxide present therein to be oxidized to form nitrogen dioxide, which is then absorbed from the flue gases to produce a nitrogen dioxide-containing solution (36) and a scrubbed flue gas. The nitrogen dioxide in the nitrogen dioxide-containing solution (36) is then reacted with ammonium hydroxide to form ammonium nitrate as a valuable byproduct.

摘要： A process and system for producing fertilizers with reduced levels of contaminants, and particularly a flue gas scrubbing process and facility that produce a fertilizer byproduct which is treated to remove heavy metals originally present in the scrubbed flue gas. The process entails contacting a flue gas with a scrubbing solution to remove acidic gases and produce a byproduct containing a fertilizer compound precipitate and dissolved metals and/or metal compounds. A fertilizer solution containing dissolved fertilizer and dissolved metals and/or metal compounds is then produced by adding water to the byproduct, after which the pH of the fertilizer solution is adjusted one or more times with a gaseous and/or liquid alkali to form precipitates of one or more metal species. The precipitates are then removed from the fertilizer solution and the solution dewatered to yield a fertilizer product with lower contaminant levels.

摘要： An apparatus (10) and process for removing acidic gases from flue gases produced by, for example, utility and industrial facilities. The acidic gases are removed as the flue gas flows upward through a contact zone (16) within a passage (13), where the flue gas is contacted with an ammonium sulfate-containing scrubbing solution to absorb the acidic gases from the flue gas. The scrubbing solution and absorbed acidic gases therein are then accumulated, and ammonia and an oxygen-containing gas are injected into the accumulated scrubbing solution to react the absorbed acidic gases and produce ammonium sulfate. An acid solution (32) is flowed across the passage (13) above the contact zone (16) of the passage (13). The scrubbed flue gas is flowed upward through the acid solution (32) to remove unreacted ammonia from the scrubbed flue gas. The acid solution (32) is then removed from the passage (13) after the acid solution (32) has been contacted by the scrubbed flue gas.

摘要： Processes and systems (10,110) for producing potassium sulfate (36) as a byproduct of a desulfurization process. Sulfur dioxide is absorbed (12) from a flue gas (14) using an ammonia-containing solution to produce an ammonium sulfate solution (24) that contains dissolved ammonium sulfate. At least a first portion (25) of the ammonium sulfate solution (24) is heated (26) before dissolving potassium chloride (22) therein to form a slurry (28) that contains potassium sulfate crystals (36) and an ammonium chloride solution. The slurry (28) is then cooled (32) to precipitate additional potassium sulfate crystals (36), after which the potassium sulfate crystals (36) are removed (34) to yield a residual ammonium chloride solution (38,48) that contains dissolved ammonium chloride and residual dissolved potassium sulfate. Ammonia (50) is then absorbed (40) into the residual ammonium chloride solution (38) to further precipitate potassium sulfate crystals (42), which are removed (44) to yield a residual ammonium chloride solution (46) that is substantially free of dissolved potassium sulfate.

摘要： A system and method suitable for the removal of pollutants from gases with a circulating dry scrubber system (12) having a circulating dry scrubber reactor (14) containing a fluidized bed adapted to contact the gas with a dry reagent within the fluidized bed. The system includes a housing (25) fluidically coupled to the reactor (14), a filter array (29) within the housing (25), and an internal hopper (28) within the housing (25) and adapted to return at least some of the particulates to the fluidized bed within the circulating dry scrubber reactor (14). The scrubbed gas stream exits the circulating dry scrubber reactor (14) and flows upward between an interior (26) of the housing (25) and an exterior of the internal hopper (28) before contacting the filter array (29). The exterior of the internal hopper (28) is exposed to the scrubbed gas stream, and the scrubbed gas stream is not recirculated to the circulating dry scrubber reactor (14) to maintain the fluidized bed therein.
