[主观题]
一乙醇胺法（MEA）Monoethanolamine method （MEA)：（）
A、吸收剂—15～25％(wt)的一乙醇胺水溶液。溶液的浓度通常根据腐蚀性和操作经验来选择。Absorbent - 15-25% (wt) monoethanolamine solution. The concentration of solution is usually chosen according to corrosiveness and operating experience.
B、脱酸气情况：特点为化学吸收过程，受压力影响小，当压力在3～7kg/cm2仍能达到管输天然气要求。Deacidification gas: it is characterized by chemical absorption process and is less affected by pressure. When the pressure is 3 ~ 7kg/cm2, it can still meet the requirements of pipeline natural gas transportation.
C、缺点：蒸气压高，挥发性强，腐蚀性强。Disadvantages: high vapor pressure, strong volatility, strong corrosion.
D、应用：此法常用于脱硫，应用广泛。Application: this method is widely used in desulfurization.
