Title (EN) PROCESS FOR RECOVERING BENZENE AND FUEL GAS IN AN AROMATICS COMPLEX
(FR) PROCÉDÉ DE RÉCUPÉRATION DE BENZÈNE ET DE GAZ COMBUSTIBLE DANS UN COMPLEXE DE COMPOSÉS AROMATIQUES
Abstract:
(EN) A process for separating xylene from a feedstock in which the feedstock is separated into a xylene stream, a benzene rich stream and a light ends stream. Two separation zones may be utilized in which liquid from both is sent to a compression zone and the vapor from the compression zone is combined with a stream prior to the stream entering the second separation zone.
(FR) L'invention concerne un procédé permettant de séparer le xylène d'une charge d'alimentation, la charge d'alimentation étant séparée en un flux de xylène, un flux riche en benzène et un flux de fractions légères. Selon l'invention, deux zones de séparation peuvent être utilisées, dans lesquelles le liquide provenant des deux zones est envoyé vers une zone de compression et la vapeur dégagée de la zone de compression est combinée avec un flux avant que le flux ne pénètre dans la deuxième zone de séparation.
