The aim of this project is a development and application of membrane techniques to increase the affectivity of classical separation processes with help of computer simulations and theoretical modelling. In most of processes the goal of separation techniques is to recycle vapor phase which was lost in a sweeping gas. The optimization of polymeric membrane for specific separation task is time consuming and financial demanding. Ionic liquids have a great potential for membrane processes especially if only a small amount of ionic liquid is necessary e.g. supported ionic liquid membranes (SILMs). Characteristic property of ionic liquid is their very low vapor pressure which makes them attractive for pervaporation.

SILMs have many advantages:

1. Molecular diffusion is much higher in ionic liquids than in polymers. 
2. Properties of SILMs are various because of wide range of chemical properties of ionic liquids.
3. Because of special mixing properties ionic liquid membranes enables three phase system existence. 
4. In contrast to extraction only a small amount of solvent is needed.
