METHOD FOR TREATING SINTERING FLUE GAS DESULFURIZATION BY-PRODUCT

摘要

A method for treating a sintering flue gas desulfurization by-product is introduced, which comprises the steps of: manufacturing a mixture by mixing calcium carbonate and carbon with by-products including sodium carbonate and sodium sulfate; melting the mixture; mixing the molten mixture with water to manufacture a mixed solution; separating precipitates containing calcium sulfide and calcium sulfate from the mixed solution; and concentrating and drying the mixed solution from which the precipitates are separated to recover an obtained product containing sodium carbonate and sodium hydrogen carbonate.;COPYRIGHT KIPO 2020
