Solution-diffusion membranes are widely used for the separation of gaseous and liquid mixtures. The separation of air (O2/N2), landfill gas (CH4/CO2) and purge gas streams (NH3/H2) in the ammonia synthesis are examples for state-of-the-art membrane gas separation processes. For the separation of liquid mixtures by means of a membrane process, i.e., pervaporation, the splitting of azeotropic mixtures of ethanol-water mixtures is a well established technique.
