CA 2440732

An improved membrane pervaporation and vapor permeation system is disclosed in which the vacuum is produced by a fluid passing through a Venturi-type nozzle. The fluid is chosen from solvents that have an affinity for the permeate molecules. It is applicable over a wide range of process feed rates, can be used with either organic or aqueous systems and converses energy relative to existing technology.

L'invention concerne un système amélioré de pervaporation par membrane et de perméation à la vapeur, dans lequel le vide est établi par le passage d'un fluide à travers une buse du type Venturi. Le fluide peut être un solvant ayant une affinité pour les molécules du perméat. Le système est utilisable pour une large gamme de débits d'alimentation de processus, et on peut l'utiliser avec des systèmes organiques ou aqueux. Enfin, il permet de réaliser des économies d'énergie par rapport à la technologie existante.
