| Abstract: | Polypropylene(PP),polysulfone(PS) and polyethersulfone(PES) hollow fiber membranes were used as novel structured packings,respectively,in contactors for iso-propanol/water distillation.In the contactor,the liquid flows through the lumens of fibers,and the vapor flows counter currently outside the fibers.Results indicate that all the contactors with above three kinds of membranes separately have higher separation efficiency than the distillation column with traditional packings.The HTU values of above hollow... |
