摘　　要：为解决气体脱硫装置使用单乙醇胺脱硫剂溶剂循环量较大，装置能耗高的问题，采用以甲基二乙醇胺为主的ＳＳＨ－１脱硫剂与单乙醇胺混合使用，在催化裂化液化气、干气脱硫装置上进行了工业试验。试验结果表明，ＳＳＨ－１脱硫剂对Ｈ２Ｓ有良好的选择性，酸性气中Ｈ２Ｓ含量达７０％；液化气及干气脱硫后Ｈ２Ｓ含量均＜５ｍｇ／ｍ３；与只用单乙醇胺相比，在原料气含硫量相近的情况下，其溶剂的循环量、再生蒸汽量、循环水用量、电耗等都有较大幅度的降低。SSH 1, a desulfurizer mainly contained methyl diethanolamine was used with monoethanolamine for desulfurizing of FCC liquefied gas and dry gas. The commercial test result showed that SSH 1 had good hydrogen sulfide selectivity; hydrogen sulfide content in acidic gas reached 70%; and the hydrogen sulfide contents in both liquefied gas and dry gas were less than 5 mg/m 3. In comparison with using monoethanolamine alone, the cycle solvent, regeneration steam, cycle water and electricity consumption were decreased significantly.
