There are various reasons for separating liquid mixtures or for changing their ratio of mixture. Pervaporation/steam permeation (membrane filtration) enables the separation of water / solvent mixtures, the separation of liquids with similar boiling points, the dehydration of multicomponent mixtures, the displacement of equilibrium in reactions where water is released and the dehydration of organic compounds. The complete system consists of an evaporator and a membrane module. lf the liquid to be separated is a distillation product, the steam can be directly passed into the membrane module. In this application the mixture is composed of water with maximum 5 % alcohol. The equipment is located in an 'ex' area.
