SEPARATION PRINCIPLE Pervaporation vs. Distillation The separation principle governing pervaporation is a combination of selective sorption/solution and diffusion. The fractionation process is mainly due to polarity differences, and not to the volatility difference of the components in the feed. It differs significantly from distillation, which depends on differences in vapour liquid equilibrium relationships. Pervaporation can be considered in situations where distillation is impossible, difficult or uneconomic - mainly for systems that demonstrate azeotropic behaviour. Pervaporation vs. Filtration
