Title
(EN) SEPARATOR AND PROCESS FOR SEPARATING VOLATILE COMPOUNDS FROM A POLYMER SOLUTION
(FR) SÉPARATEUR ET PROCESSUS DE SÉPARATION DE COMPOSÉS VOLATILS D'UNE SOLUTION POLYMÈRE
Abstract
(EN)
The present invention is concerned with a separator comprising a vessel, a first inlet, a second inlet, a first outlet, a second outlet, and a separation device located downstream of the first outlet, wherein the separation device comprises two outlets, whereas one outlet of the separation device is fluidly connected to the second inlet of the vessel. Furthermore, the present invention is also concerned with a process for separating hydrocarbons from a reaction solution comprising a polymer and said hydrocarbons, comprising the steps of passing the reaction solution through the first inlet into the separator according to the invention, withdrawing a first outlet stream through the first outlet, withdrawing a second outlet stream through the second outlet, separting the first outlet stream in the separation device to produce a first separated stream and a second separated stream, withdrawing the first separated stream from the separation device and passing the first separated stream through the second inlet into the vessel, and withdrawing the second separated stream from the separation device.

La présente invention concerne un séparateur comprenant un récipient, une première entrée, une seconde entrée, une première sortie, une seconde sortie, et un dispositif de séparation situé en aval de la première sortie, le dispositif de séparation comprenant deux sorties, tandis qu'une sortie du dispositif de séparation est en communication fluidique avec la seconde entrée du récipient. En outre, la présente invention concerne également un processus de séparation d'hydrocarbures à partir d'une solution de réaction comprenant un polymère et lesdits hydrocarbures, comprenant les étapes consistant à faire passer la solution de réaction à travers la première entrée dans le séparateur selon l'invention, à retirer un premier flux de sortie à travers la première sortie, à retirer un second flux de sortie à travers la seconde sortie, séparer le premier flux de sortie dans le dispositif de séparation pour produire un premier flux séparé et un second flux séparé, à retirer le premier flux séparé du dispositif de séparation et à faire passer le premier flux séparé à travers la seconde entrée dans le récipient, et à retirer le second flux séparé du dispositif de séparation.
