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.
D、以上都不对
A、采用某种溶于水的溶剂和酸性气体(H2S、CO2)反应生成“复合物”。"Complex" is formed by reaction of some water-soluble solvent and acidic gas (H2S, CO2).
B、溶剂以化学结合的方式“吸住”酸性组分——净化;The solvent "absorbs" the acidic component in a chemically bonded way -- purification;
C、“吸住”酸性组分的富液因温度上升和压力下降,“复合物”分解放出酸性组分——溶液再生。As the temperature rises and pressure drops, the "complex" decomposes and releases the acidic component -- solution regeneration.
D、烷基醇胺法: 一乙醇胺法(MEA) ,改良二乙醇胺法(SNPA-DEA法) ,二甘醇胺法(DGA法) ,二异丙醇胺法(ADIP)/Alkyl alcohol amine method: monoethanolamine method (MEA), modified diethanolamine method (snpa-dea method), diethylene glycol amine method (DGA method), diisopropanolamine method (ADIP method)
E、碱性盐溶液法: 改良热钾碱法/Basic salt solution method: modified hot potassium alkali method
