"II. Cher professeurs,好老师们，水提工艺因为用水作为溶剂不考虑回收问题是不是液环就可以呢？还是是不是液环对水汽的抽气能力强？如果是醇提，是否是否选是否选干式泵好回收酒精等的溶剂呢？还是有其他的优势？"

"水提、醇提都可以水提、醇提都可以用可以用液环真空泵。醇提时、醇类作为冷却循环介质。醇提时，冷却循环介质用醇。 �要看你需要达到的真空度是多少才能决定采用的真空泵。真空度要求很高时、还需要不同真空泵组合才能达到。"

"谢谢老师。如果醇提用液环的、介质用醇、用户成本会提高的吧。该怎么做回收呢"

"真空泵的排气要加冷凝器、将带走的醇冷下来"

"醇提用干泵好。用液环、醇类进入水里、会改变工作液饱和蒸气压、影响真空度。。。"
