Title (EN) OPERATION METHOD OF A PLANT FOR DISTILLING LIQUID PRODUCTS AND PLANT FOR REALISING THE SAME
(FR) PROCEDE DE FONCTIONNEMENT D'UNE INSTALLATION DE DISTILLATION DE PRODUITS LIQUIDES, ET INSTALLATION PERMETTANT DE METTRE EN OEUVRE CE PROCEDE
Abstract:
(EN) The present invention pertains to the field of petroleum chemistry and essentially relates to a method that comprises feeding into an ejector nozzle a liquid working medium having a molecular weight of more than 100. The mixture of the working media is fed from the ejector into a profiled vessel where the flow rate of said working media is slowed down while increasing the static pressure value. This invention also relates to a device for realising this method, wherein said device consists of a plant that includes a profiled vessel. The outlet of the ejector is connected to the inlet of the profiled vessel while the inlet of a separator is connected to the outlet of said vessel. The operation method and the plant described in this invention ensure a more efficient operation.
(FR) Cette invention se rapporte au domaine de la pétrochimie et concerne essentiellement un procédé qui consiste à envoyer dans la buse d'un éjecteur un milieu de travail liquide qui possède une masse moléculaire supérieure à 100. Le mélange de milieux de travail provenant de l'éjecteur est envoyé dans un récipient profilé dans lequel on ralentit la vitesse d'écoulement du flux de mélange desdits milieux, tandis que l'on augmente la valeur de la pression statique. Cette invention concerne également un dispositif de mise en oeuvre de ce procédé, lequel consiste en une installation qui comprend un récipient profilé. La sortie de l'éjecteur est reliée à l'entrée du récipient profilé, tandis que l'entrée du séparateur est connectée à la sortie dudit récipient. Ce procédé de fonctionnement et l'installation réalisée d'après ce procédé assurent une meilleure efficacité de fonctionnement.
