Abstract

PURPOSE:To separate a dissolving volatile substance efficiently by bringing a raw solution in which the volatile substance dissolves into contact with one side of a hydrophobic porous membrane having continuous fine pores and bringing an aqoueous solution for recovery at lower temperature than the raw material into contact with the other side of the membrane. CONSTITUTION:In the case where an ethanol-containing aqueous solution as a raw material and distilled water are respectively brought into contact with one side of a hydrophobic porous membrane and with the other side, gaseous layers 4, 6 are formed on the surface of the hydrophobic porous membrane and gas-liquid interfaces 3, 7 exist outer side of the layers. When the raw material 1 flows, a liquid boundary membrane exists in the liquid side and ethanol molecules move in the boundary membrane due to diffusion. When a gas and a liquid are not in the equilibrium state in the gas-liquid interface 3, ethanol and water are evaporated according to the gas- liquid equilibrium theory and move in the gas on the surface of the membrane and in the membrane owing to gas diffusion. As an apparatus, one by which the raw material solution and an absorption liquid are respectively brought into contact with one side and the other of a hydrophobic flat membrane is preferable.
