Title (EN) PROCESS FOR THE PRODUCTION OF A POLYMER USING A COMPOUND COMPRISING AT LEAST 2 UNSATURATED CARBON-CARBON BONDS
(FR) PROCÉDÉ DE PRODUCTION D'UN POLYMÈRE À L'AIDE D'UN COMPOSÉ COMPRENANT AU MOINS 2 LIAISONS CARBONE-CARBONE INSATURÉES
Abstract:
(EN) The present invention relates to a process for the production of a polymer using a compound comprising at least 2 unsaturated carbon-carbon bonds, wherein the process comprises a polymerisation section and a purification section, wherein the product from the polymerisation section is subjected in the purification section to a sequence of purification steps comprising: ∙ removal of the vapour phase from the product from the polymerisation section by means of flash separation to obtain a first vapour phase and a polymerisation product; ∙ subjecting the first vapour phase to a compression and condensation treatment to obtain a second vapour phase and a condensed monomer phase; wherein the purification steps are conducted in this order. Such process allows for the optimal utilisation of raw materials in the polymerisation process.
(FR) La présente invention concerne un procédé de production d'un polymère à l'aide d'un composé comprenant au moins 2 liaisons carbone-carbone insaturées, le procédé comprenant une section de polymérisation et une section de purification, le produit provenant de la section de polymérisation étant soumis dans la section de purification à une séquence d'étapes de purification comprenant : ∙ l'élimination de la phase vapeur du produit de la section de polymérisation au moyen d'une séparation instantanée pour obtenir une première phase vapeur et un produit de polymérisation ; ∙ la soumission de la première phase vapeur à un traitement de compression et de condensation pour obtenir une seconde phase vapeur et une phase monomère condensée ; les étapes de purification étant effectuées dans cet ordre. Un tel procédé permet l'utilisation optimale des matières premières lors du processus de polymérisation.
