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.
