中国大学MOOC: 化学溶剂法Chemical solvent method()
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). “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. 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) 碱性盐溶液法: 改良热钾碱法/Basic salt solution method: modified hot potassium alkali method
