Abstract
Le chlorure de vinyle est séparé d'une dispersion aqueuse qui contient 5 à 50 % en poids de résine de chlorure de vinyle et 1 000 à 15 000 ppm de chlorure de vinyle. Le dispersion aqueuse est tout d'abord mise en contact avec de la vapeur d'eau et de l'acétate de vinyle afin d'en séparer au moins 90 % du chlorure de vinyle, puis, à la fin d'une courte période de conditionnement, elle est mise en contact avec de la vapeur d'eau afin d'abaisser sa teneur en monomère à moins de 10 ppm. Application à l'épuration des résines de chlorure de vinyle.
