Definition

A membrane separation process in which components of a liquid mixture selectively sorb into and permeate through a non‑porous (dense) membrane and re‑evaporate on the downstream side under reduced pressure or a sweep gas, so that the permeate is removed as vapor and the retentate is enriched in the less permeating species; selectivity is governed by sorption and diffusion differences and phase cha
