FIELD: process engineering.
SUBSTANCE: invention relates to membrane processes and can be used in extraction of organic processes from solutions. Invention covers liquid membrane arranged on phase interface surface and made up of a layer of hydrophobic liquid, 3-30 mm-thick oil layer. Invention covers also method of extracting alcohols or ethers from water solutions by their diffusion evaporation through said membrane using gas or vacuum.
EFFECT: simplified process, lower costs.
