A.
吸收剂—25~30%(wt)的二乙醇胺水溶液Absorbent - 25 ~ 30% (wt) diethanolamine solution
B.
脱酸气情况:适用于高压、高酸气浓度、高H2S/CO2比值的天然气净化,当H2S分压达到4kg/cm2,比MEA法经济。Deacidification gas: it is suitable for gas purification with high pressure, high concentration of acid gas and high H2S/CO2 ratio. When H2S partial pressure reaches 4kg/cm2, it is more economical than MEA method.
C.
蒸发损失小,腐蚀性小,所需再生热量少。Evaporation loss is small, corrosion is small, the need for regenerative heat.
