摘要： The present invention is a process, a method, and system for recovery and concentration of dissolved ammonium bicarbonate from a wastewater containing ammonia (NH3) using gas separation, condensation, and crystallization, each at controlled operating temperatures. The present invention includes 1) removal of ammonia from waste (sludges, semi-solids, and solids and liquids) without the use of chemicals at a temperature of at least 80 degrees Celsius, 2) condensing the gaseous containing ammonia, carbon dioxide and water vapor to remove water vapor concentrating the amount of gaseous ammonia and carbon dioxide, 3) concentrating the ammonia and carbon dioxide in the water by established means, such as concentrating the gas using partial condensation followed by passing the concentrated gas through an absorption column at a temperature of between about 20 and 50 degrees Celsius to form dissolved ammonium carbonate and ammonium bicarbonate, or total condensation followed by dewatering using reverse osmosis, and 4) crystallizing concentrated dissolved ammonium carbonate and ammonium bicarbonate at a temperature of less than about 35 degrees Celsius to form solid ammonium bicarbonate and ammonium carbonate.

摘要： Device and methods for producing ammonium bicarbonate in an ammonia-based decarbonization system are provided. The device may include a cooling function zone, an ammonium bicarbonate generation zone, a carbon dioxide absorption zone and an ammonia removal function zone. The cooling function zone may remove heat from the decarbonization system. The ammonium bicarbonate generation zone may generate ammonium bicarbonate. The carbon dioxide absorption zone, which may use multi-stage absorption, may absorb carbon dioxide in process gas. The ammonia removal function zone may remove ammonia in decarbonized process gas. Absorbent ammonia for carbon dioxide removal may be mainly fed to the absorption zone. As a result of the zone control of ammonium bicarbonate generation, CO2 absorption and ammonia removal, the efficiency of decarbonization and absorption may be improved, and ammonia escape may be reduced. Meanwhile, carbon dioxide in flue gas can be used for producing ammonium bicarbonate as a nitrogen fertilizer.

摘要： A method for recovering ammoniacal nitrogen, in the form of ammonium carbonate and/or ammonium bicarbonate, from an ammoniacal nitrogen-containing vapor that comprises introducing said vapor into at least one pressurizable ammonia scrubbing vessel containing water, simultaneously introducing a carbon dioxide-containing vapor into at least one pressurizable carbon dioxide scrubbing vessel containing water, and simultaneously pumping the solutions created in said scrubbers via hydrologic connections between said scrubbers to mix the solution to create an ammonium carbonate and/or ammonium bicarbonate containing mixture, all while maintaining independent and unmixed vapor streams throughout the entire process. The method further involves recovering ammonium carbonate and/or ammonium bicarbonate from the mixture for further use.

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： An objective of the present invention is to provide a glycan releasing method which can be applied to construction of a system for automation of glycan analysis, and particularly a glycan releasing method capable of analyzing an O-linked glycan. The objective could be achieved as a result of finding that the pH is lowered by using an ammonium salt or ammonium ion in the absence of concentrated aqueous ammonia, not using concentrated aqueous ammonia, thus drastically avoiding an undesired side reaction such as a peeling reaction or the like. Therefore, the present invention provides a method of producing an O-linked glycan from a glycan-binding substance having the O-linked glycan, the method includes the steps of (A) bringing an ammonium salt or ammonium ion into contact with the glycan-binding substance in the absence of concentrated aqueous ammonia (for example, under the conditions of the pH of about 7 or higher and lower than about 11); (B) neutralizing the reaction solution obtained in step (A); and (C) collecting the released glycan.

摘要： The present invention is a process for the conversion of aluminum oxide hydroxide (AlOOH) to aluminum oxide. About 30 to 70 wt-% of AlOOH, about 30 to 70 wt-% ammonium hydrogencarbonate NH4HCO3 and 0 to 20 wt-% water are combined to produce a mixture. This mixture is then cured at a temperature from about 30° to about 90° C. to convert at least 5% of the AlOOH to a ammonium hydroxycarbonate (dawsonite-type) intermediate and then the dawsonite-type intermediate is decomposed at a temperature from about 130° to 320° C. to produce aluminum oxide. The aluminum oxide can be further calcined at 500° to 800° C. to produce a gamma-theta phase alumina.
