Abstract: 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.

Abstract: Waste heat recovery in an ammonia-based desulfurization and decarbonization system. The heat in the decarbonization system may be removed by using the heat of the process gas before desulfurization. The process gas before desulfurization may heat an intermediate medium through a gas heat exchanger. The intermediate medium may drive a refrigerator for refrigeration. A refrigerant may obtain the cooling capacity and may then cool the decarbonized process gas through a liquid-liquid heat exchanger.
