摘　　要：高炉煤气中通常含有H_(2)S、COS和CS_(2)等硫化物,燃烧后产生的SO_(2)浓度较高,造成下游工序烟尘排放浓度难以满足超低排放要求。为解决该问题,分析对比了现有的高炉煤气精脱硫工艺,并结合华中某钢铁企业煤气脱硫技术的应用案例,重点介绍了催化水解+干法精脱硫工艺,以期为行业高炉煤气精脱硫工艺的选择提供技术参考。Blast furnace gas typically contains sulfides such as H_(2)S,COS,and CS_(2),which produce high concentrations of SO_(2)after combustion,making it difficult for downstream processes to meet ultra-low emission requirements.To address this issue,this paper analyzes and compares existing blast furnace gas fine desulfurization processes.Combined with a case study of gas desulfurization technology application in a steel enterprise in Central China,the catalytic hydrolysis+dry fine desulfurization process is highlighted,providing technical references for the selection of blast furnace gas fine desulfurization processes in the industry.
