Simulation of a pervaporation system on the industrial scale for water treatment Part I: Extended resistance-in-series model

The resistance-in-series model has been used by several authors to describe the pervaporation of dilute solutions. This paper extends the use of this model to encompass support layer (or vapour side) resistance, membrane swelling and component concentrations in the vapour mixture. The definition of an enhancement factor for the membrane top layer diffusion coefficient, similar to conventional heat and mass transfer equations, both facilitates …
