摘　　要：探讨了炼厂气用作燃料的脱硫净化度要求 ,建议H2 S浓度不大于 10 0mg/m3,总硫浓度不大于 50 0mg/m3,分析了脱硫溶剂的选择及脱硫中存在的问题 ,提出了相应的改进措施 :应减少原料气重烃含量 ,加强溶剂过滤 ,确定适宜的贫溶剂入吸收塔温度 ,搞好富溶剂集中再生 ,确定适宜的溶剂再生塔底温度并加强脱硫溶剂的管理工作。The purity demand when using refinery gas as fuel was explored.It is suggested that the H 2S should be less than 100 mg/m 3 and the total sulfur below 500 mg/m 3.The selection of desulfurizing solvent was analyzed and improving measures proposed,i e,reducing the content of heavy hydrocarbon in feedstock gas,improving solvent filtration,setting suitable temperature of the lean solvent at the inlet of absorber,using central regeneration of the rich solvent,setting suitable temperature of solvent regenerating tower and strengthening management on desulfurizing solvents.
