摘　　要：用络合铁脱硫工艺替代原有的MTS钠法脱硫工艺。在优化后的工艺条件下,脱硫效率可长期稳定控制在99.5%以上,脱硫塔后焦炉煤气H_(2)S含量低于20 mg/m^(3),脱硫液中副盐含量稳定低于250 g/L。This paper introduced replacement of original MTS sodium desulfurization process with complex iron desulfurization process.After optimization of the process,the desulfurization efficiency can be stably controlled above 99.5%for a long time.The H_(2)S content in coke oven gas after the desulfurization column is less than 20 mg/m^(3),and the secondary salt content in the desulfurization solution remains stable below 250 g/L.
