Beschreibung
Zusammenfassung:	A multi-layer membrane structure including a crosslinked polymeric membrane, such as a crosslinked polyvinyl sulfate membrane or a crosslinked copolymer polyvinyl sulfate and polyvinyl alcohol membrane, is provided. The membrane structure is suitable for use in an acid environment, and is suitable for recovering acid from a feed mixture comprising acid, hydrocarbons and water. L'invention concerne une structure de membrane multicouche comprenant une membrane polymère réticulée, telle qu'une membrane à base de sulfate de polyvinyle réticulée ou une membrane à base d'alcool polyvinylique et de sulfate de polyvinyle copolymère réticulée. La structure de membrane est appropriée pour être utilisée dans un environnement acide et est appropriée pour la récupération d'acide d'un mélange d'alimentation comprenant de l'acide, des hydrocarbures et de l'eau.
