2019-5-26 · This process consists of 2 fluidized bed reactors connected by solid transportation lines. In one reactor (absorber), flue gas CO2 is captured by CaO at 873 K and the produced CaCO3 is transported to another reactor (regenerator), in which CaCO3 is decompd. to CaO at 1223 K. The produced CaO is transported to the absorber again.
1977-7-5 · Process for control of SO x emissions from copper smelter operations involving pyrometallurgical reduction of copper ores to elemental copper in which the gases from reverberatory furnaces, roasters, and/or converters are scrubbed with a sodium alkali sorbent to produce sodium sulfate and sulfite wastes. The cleaned flue gases are exhausted to the atmosphere.
