A pervaporation process characterized by a low driving force and low feed/permeate pressure ratio, obtained by operating at permeate pressures above 50 torr (6.7 KPa) or at low feed temperatures. The process is effective in controlling concentration polarization in pervaporation separations of components of high relative volatility, where the evaporative term has a significant effect on the overall separation factor. The process is particularly useful for separating VOCs from water, or for separating organic mixtures.

L'invention concerne un procédé de d'évaporation transmembranaire qui fait appel à une force de commande réduite et une faible pression d'alimentation/perméation, obtenu par fonctionnement à des pressions de perméation, supérieures à 50 torr (6,7 Kpa) ou à de basses températures d'alimentation. Ce procédé permet de vérifier la polarisation de la concentration dans des processus de séparation par évaporation transmembranaire de composants à volativité relative élevée, où la durée d'évaporation exerce un effet significatif sur le facteur de séparation global. Ce procédé s'utilise notamment pour séparer les composés organiques volatils contenus dans l'eau ou pour séparer des mélanges organiques.
