in the chemical industry, process intensification is needed to meet important goals such as sustainable and eco-friendly processes. for esterification reaction the “produce more with less pollution” objective can be achieved by coupling reaction and separation in a so called integrated process. in this work a model for describing the esterification reaction of ethyl acetate in pervaporation mem...

in this research, polyvinylchloride based composite heterogeneous cation exchange membranes were prepared by the solution casting technique. chitosan-co-iron nickel oxide nanoparticles were utilized as membrane surface modifier to improve the membranes electrochemical properties. the effect of additive nanoparticle concentration in the modifier solution on the properties of composite membranes ...

In this paper, the variation of permselectivity in the course of concentration polarization is systematically analyzed for a three-layer membrane system consisting of a nonperfectly permselective ion exchange membrane, homogeneous or heterogeneous, flanked by two diffusion layers of a binary univalent electrolyte. For a heterogeneous membrane, an ionic transport model is proposed, which is amen...
