第1题
A、吸收剂——25~30%(wt)的二异丙醇胺水溶液Absorbent - diisopropanolamine solution of 25 ~ 30% (wt)
B、脱硫情况:与一乙醇胺大致相似,可以脱除部分有机硫化物,在CO2存在时对H2S吸收有一定选择性,腐蚀性小,胺损失量小,蒸汽消耗较一乙醇胺法小。Desulfurization: similar to monoethanolamine, it can remove some organic sulfide, and has a certain selectivity for H2S absorption in the presence of CO2. It is less corrosive, less amine loss, and less steam consumption than monoethanolamine.
C、应用:主要用于炼厂气脱硫Application: mainly used in refinery gas desulfurization
D、以上都不对
