This paper deals with a description of transport parameters during pervaporation of binary liquid mixture through non-porous polymer membrane. The influence of the C-number of aliphatic alcohols on transport parameters is also under study. The concentration dependent density of the membrane, vapor sorption isotherms, the dependence of pure component diffusion coefficients on their concentration in the membrane and the dependence of the solubility of liquid binary mixture in a membrane was necessary to determine experimentally.
