Comparison of various models for transport of binary mixtures through dense polymer membrane

Original language description

The main aim of this work is the application of various models describing the transport of a penetrant during pervaporation process in the membrane and their comparison.We experimentally determined sorption isotherms of pure components, diffusion coefficients, non-ideal sorption of liquid binary mixture in a membrane and the density of the membrane versus concentration composition. All mentioned dependencies were mathematically described and then introduced into a Flory-Rehner equations, UNIFAP model and modified Maxwell-Stefan equations. Models were used for description of the transport of liquid binary mixtures (pentan-1-ol, hexan-1-ol with toluene) through the low-density polyethylene membrane at 25 °C. Calculated pervaporation fluxes and separationdiagrams were compared with the results of the experiments.
