Abstract

Using a solution-diffusion mechanism, the rate of mass transport in pervaporation process was determined. A method to determine the parameters of the applied model, i.e., mass transport coefficients in the liquid and gas phase and partition coefficients on both sides of membrane surface was presented. Experiments were conducted in phenol-water and p-cresol-water system using a PDMS composite membrane (Pervatech, the Netherlands). Results of vacuum pervaporation were used to calculate mass transfer resistance in the liquid phase and the partition coefficient on the membrane surface. Experimental values obtained in vacuum pervaporation have shown that resistance in the liquid phase is in the range from 10 to 40% of the total resistance and cannot be neglected. The experiments with a sweep gas pervaporation process allowed to determine mass transport resistance in the inert phase, which appeared to be a limiting parameter of the mass transport rate. © 2011 Taylor & Francis Group, LLC.
