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.
