Description of binary liquid mixtures transport through non-porous membrane by modified Maxwell-Stefan equations

Popis výsledku v původním jazyce

This paper deals with a description of transport parameters during pervaporation of binary liquid mixture through non-porous polymer membrane. The main task of this work is the application of the model that would be able to describe the transport of thepenetrant in the 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. All mention dependencies were mathematically described and then introduced into modified Maxwell-Stefan equations. The model was used for the liquid binary mixtures (ethanol, propan-1-ol, butan-1-ol with toluene) and the low-density polyethylene membrane at 25 °C. Pervaporation data for all the three systems were measured in or
