膜分离

Energy-saving ethanol dehydration techniques to produce dehydrated alcohol mainly included four measures as azeotropy distillation, extraction distillation, absorptive process and membrane separation.

摘要节能型乙醇脱水制备无水乙醇的方法主要有4种：共沸精馏法、萃取精馏法、吸附法和膜离法。

Adsorbable gases can be separated by porous ceramic membranes under the capillary condensation mechanism of membrane separation, on which prior study was only limited to pure components.

多孔陶瓷膜在毛细传质机理的用下能够有离吸附性气体。而毛细膜离传质机理的研究还很不充,目前,文献报道仅局限于纯组气体的传质模型研究。
