Abstract

Pervaporation process which is a useful membrane separation technique for wide varieties of organic liquid mixtures has recently been noted. This method can be expected to be useful particularly for separation of close-boiling mixtures, azeotropic mixtures and others. Since the criteria in membrane separation process is to develop excellent membrane, we must properly evaluate the membrane functionality such as selectivity and durability. In this chapter, pervaporation apparatus, operation procedures, presentation of experiment data, problems in measurement, factors affecting separation and mathematical treatment were described.
