Abstract
In present work the nonequilibrium thermodynamic advantages for pervaporation process approximation are discussed. The calculation model, which aligns nonequilibrium thermodynamic, pervaporation data and vapor-liquid equilibrium data, is presented. The approximation of vapor-liquid equilibrium data for feed mixtures was performed by Wilson and NRTL equations. Approbation of proposed approach with the use of different membranes was carried out for six binary systems: methanol-water, ethanol-water, propanol-1-water, propanol-2-water, butanol-1-water and acetone-water. The compatibility between the experimental pervaporation data and the results of estimation are discussed.
