SEPARATION PRINCIPLE Pervaporation vs. Distillation The separation principle governing pervaporation is a combination of selective sorption/solution and diffusion. 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
