A method of liquid mixture separation in which a substance having a molecular weight of 90 or higher is selectively separated from a liquid mixture (31) with a separation membrane. The separation membrane is an MFI-type zeolite membrane (2). The method of liquid mixture separation comprises bringing the liquid mixture (31) into contact with one side of the MFI-type zeolite membrane (2), reducing the pressure on the other side of the MFI-type zeolite membrane (2), and collecting a substance (32) which has passed through the MFI- type zeolite membrane (2). The method of liquid mixture separation enables a given substance to be separated from a liquid mixture without the need of a high energy cost.

La présente invention concerne un procédé de séparation d~un mélange liquide dans lequel une substance ayant une masse moléculaire supérieure ou égale à 90 est sélectivement séparée d'un mélange liquide (31) avec une membrane de séparation. La membrane de séparation est une membrane de zéolite de type MFI (2). Le procédé de séparation d~un mélange liquide comprend la mise en contact du mélange liquide (31) avec un côté de la membrane de zéolite de type MFI (2), la réduction de la pression de l'autre côté de la membrane de zéolite de type MFI (2) et la collecte d~une substance (32) qui a traversé la membrane de zéolite de type MFI (2). Le procédé de séparation d~un mélange liquide permet à une substance donnée d~être séparée d~un mélange liquide sans la nécessité d~un coût énergétique élevé.
