PERVAPORATION SEPARATION OF BENZENE/CYCLOHEXANE MIXTURES USING MATRIMID® POLYIMIDE MEMBRANES

Separation of benzene/cyclohexane mixtures is one of the most challenging industrial problems which is traditionally carried out using extractive or azeotropic distillation. Pervaporation membrane process could be considered as an appropriate replacement for these complex and expensive processes. Polyimide is a resistant polymer which could be employed to prepare polymeric membranes for this purpose. In the present study matrimid membranes were prepared and applied for the separation. The obtained results including the flux and ideal selectivity of membranes represent the potential of this polymer for organic-organic separations.
