【多选题】针对不同原料气提出的脱硫方法不下数十种,大致可分为大类There are more than ten kinds of desulfurization methods for different raw gas, which can be divided into four categories:()
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.
