Title
(EN) SEPARATING METHOD OF FLUORINE-CONTAINING SOLVENT, REMOVING METHOD OF FLUORINE-CONTAINING SOLVENT CONTAMINANT, AND APPARATUS THEREFORE
(FR) PROCÉDÉ DE SÉPARATION DE SOLVANT CONTENANT DU FLUOR, PROCÉDÉ D'ÉLIMINATION DE CONTAMINANT DE SOLVANT CONTENANT DU FLUOR, ET APPAREIL À CET EFFET
Abstract
(EN)
An object of the invention is to separate a fluorine-containing solvent in a short time and efficiently from a fluorine-containing solvent which contains alcohol. There is provided a method for separating a fluorine-containing solvent by filtering a mixed liquid composition containing the fluorine-containing solvent, alcohol and water with a membrane containing fluorine resin.
(FR)
La présente invention concerne la séparation d'un solvant contenant du fluor en une courte période de temps et efficacement à partir d'un solvant contenant du fluor qui comporte de l'alcool. L'invention porte plus particulièrement sur un procédé de séparation d'un solvant contenant du fluor par filtrage d'une composition liquide mixte comportant de l'alcool, de l'eau et le solvant contenant du fluor avec une membrane contenant une résine de fluor.
