Abstract
L'invention concerne un appareil (100) et un procédé qui permettent de séparer de l'eau résiduelle d'un solvant. Le dispositif comprend un réservoir (102) rempli d'une solution qui comprend de l'eau résiduelle contenant un solvant. Le réservoir est muni d'une ouverture servant à l'écoulement de la solution du réservoir. Une couche membranaire présente une première couche de polymère fluoré (104) et une seconde couche de polymère fluoré (105). La membrane est disposée en série avec l'ouverture du réservoir. De la vapeur est générée sur un côté de la couche membranaire et l'eau contenant un solvant passe à travers la membrane et y est séparée du solvant pour donner un solvant dont la teneur en eau est inférieure ou égale à 1,0 mg/l.
