Abstract
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.
