摘要： Sludge from an anaerobic digester is treated to recover one or more of fibers, or solids or liquids with a high nutrient content. The solids or liquids can be used as a fertilizer. The fibers can be used in a plant growing medium. Solids are separated from liquids in the sludge and dried. The solids may be dried to produce a flake or pellet. Ammonia in the liquids is recovered and used to produce a concentrated acidic ammonium salt solution. This solution may be mixed with the solids to produce a nitrogen enhanced solid. The fibers and solids or liquids can also be used in combination to produce an enhanced plant growing medium. A device and process for removing ammonia from a liquid can be used in the system or separately.

摘要： A method of recovering ammonia by the distillation of an aqueous solution containing ammonia, carbon dioxide and hydrogen cyanide. The distillation is conducted using a distillation apparatus having at least its portion which comes into contact with the aqueous solution made of an alloy 1 or alloy 2. The alloy 1 contains 3% by weight or more of molybdenum, 15% by weight or more of nickel and 15% by weight or more of chromium. The alloy 2 contains 1% by weight or more of molybdenum, 9% by weight or less of nickel and 20% by weight or more of chromium.

摘要： Ammonia is recovered from waste water containing NH3, at least one acid gas (CO2, H2S) and inert gases. Firstly, the waste water is passed through a pretreatment column and then, at least in part, into a total stripping column. The top product from the total stripping column is cooled in a condenser, and an aqueous NH3-containing condensate coming from the condenser is fed to an NH3 stripping column. The top product from the NH3 stripping column is brought into direct contact with circulating aqueous NH3-containing condensate in a wash column, and NH3 is recovered from the top product from the wash column. Some of the bottom product from the wash column is fed back into the NH3 stripping column. The temperature in the bottom region of the pretreatment column is set to from less than 30 to 200° C., a sub-stream of the waste water is introduced into the upper region of the pretreatment column, and a second sub-stream of the waste water is fed into the pretreatment column below the first sub-stream. At least 80% of the NH3 introduced from the total stripping column is condensed in the condenser. A waste-water stream is taken off from the total stripping column, at least part thereof is cooled to temperatures of from 10 to 60° C., and the cooled waste-water stream is passed into the top region of the pretreatment column.

摘要： The present invention relates to an improved process for distilling ammonia from a mixture, more particular from a mixture resulting from the reaction between aminonitrile and water (which reaction is also called cyclizing hydrolysis). The process for distilling the ammonia contained in an aqueous caprolactam solution, uses a column with a bottom temperature less than or equal to 160° C. and at an absolute pressure less than or equal to 5 bar, the ammonia distilled at the top of the column being compressed to a pressure greater than or equal to 10 bar and then condensed at a temperature of 25° C. to 60° C.

After not less than 60% of the ammonia has been recovered as liquid ammonia from the product solution, the remaining ammonia is recovered as aqueous ammonia solution through the steps of stripping and absorption in water. Separately, a dialkanolamine can be selectively and efficiently produced by circulating part of the product solution to the reactor.

摘要： A process for the granulation of precipitation products, formed from the reaction of ammonium compounds with alkaline-earth compounds, by introducing into the bottom of a reaction chamber an ammonium and alkaline-earth compound such that the alkaline-earth compound in aqueous solution is immediately and intimately mixed with the ammonium compound to form alkaline-earth compound precipitation products in the form of hard granules which are difficultly soluble in water. The alkaline-earth precipitation products are easily withdrawn from the bottom of the reaction chamber without forming a lime sludge which is difficult to remove.
