Abstract
An apparatus for membrane pervaporation, in which a raw feed chamber, constituting two partial chambers, is formed by two plates. On the respective sides of each plate which are faced away from each other, there is a surrounding profile, which serves as support for the membrane. A surrounding gasket is arranged between the respective plate and the membrane such that the compaction of the gasket is limited to a predetermined value. Several raw feed chambers and permeate chambers can be alternately arranged in a stack unit. The apparatus is characterized by a simple design and low number of elements.
