China Nonferrous Metallurgy

Based on the current national requirements for air pollutant emission limits of non-ferrous metal industries and industry policy specifications, this paper compares and analyzes the advantages and disadvantages of the current flue gas desulfurization technologies, and the two flue gas treatment schemes of a copper smelter were comprehensively compared. The results show that various flue gas desulfurization technologies have advantages and disadvantages, and it is difficult to find a perfect desulfurization technology. The selection of flue gas desulfurization process technology requires comprehensive consideration of equipment investment costs, facility footprint, desulfurization agent costs and supply stability, by-product disposal and benefits, etc., calculate technical costs and operating costs, and select the most cost-effective desulfurization process.
