Title
(EN) SOLIDS CONTENT CONTROL IN IONIC LIQUID ALKYLATION PROCESS
(FR) RÉGULATION DE LA TENEUR EN SOLIDES DANS UN PROCÉDÉ D'ALKYLATION EN LIQUIDE IONIQUE
Abstract
(EN)
The present invention relates to a continuous or non- continuous ionic liquid alkylation process comprising a step for solids removal, the process further comprising the steps (a) measuring the solids content in the ionic liquid alkylation process stream by on line (in situ) or off line sampling; (b) in response to the solids measurement signal, regulating the flow of the ionic liquid side stream to be sent to the solids removal device; (c) regulating the flow of the fresh ionic liquid inlet stream, for controlling the solids content in the ionic liquid alkylation process to a pre-defined level. The process of the invention provides a means to more efficiently run an ionic liquid alkylation process.
(FR)
La présente invention concerne un procédé d'alkylation continue ou non continue en liquide ionique comprenant une étape consistant à éliminer des solides, le procédé comprenant en outre les étapes consistant à (a) mesurer la teneur en solides dans le courant à traiter par alkylation en liquide ionique par échantillonnage continu (in situ) ou discontinu ; (b) en réponse au signal de mesure de la teneur en solides, réguler le débit du courant latéral de liquide ionique à envoyer au dispositif d'élimination des solides ; (c) réguler le débit du courant d'entrée de liquide ionique non altéré, afin de réguler la teneur en solides dans le procédé d'alkylation en liquide ionique à un niveau prédéfini. Le procédé selon l'invention fournit un moyen permettant de mettre en œuvre de manière plus efficace un procédé d'alkylation en liquide ionique.
