The LJS -FGD technology and limestone -gypsum wet technology were used for desulfurization of sintering gas in the two major iron and steel enterprises in Tianjin. After further analyzing the engineering data of two kinds of desulfurization methods, compared the desulfurization, dust removal and denitration effects, energy consumption indicator, etc.. On the basis of guarantee the desulfurization and denitration effects, the LJS -FGD technology had the advantages of low investment, small footprint, low energy consumption, low pollution and low running cost, etc., but the limestone-gypsum wet technology had the disadvantage of high energy consumption, high footprint and easy to corrosion of the equipment, etc.
