Title
(EN) PROCESS FOR THE VACUUM DISTILLATION OF A LIQUID PRODUCT, PREFERABLY CRUDE PETROLEUM, AND A FACILITY FOR CARRYING OUT THE PROCESS
(FR) PROCEDE DE DISTILLATION SOUS VIDE D'UN PRODUIT LIQUIDE, DE PREFERENCE DU PETROLE BRUT ET SON INSTALLATION DE MISE EN OEUVRE
Abstract
(EN)
The proposed vacuum distillation process involves dividing the liquid product fed into a vessel under a vacuum into a steam/gas phase and at least one liquid fraction, removal of the steam/gas phase from the vessel using a vacuum-producing device, and subsequent division of the steam/gas phase into a gas and a liquid phase by condensation directly in the vacuum-producing device. A portion of the liquid phase is used as a liquid working medium for the vacuum-producing device. The proposed vacuum distillation facility comprises a vacuum vessel with pipes and a vacuum-producing device which includes a jet blower, separator and pump, these elements being interconnected by pipes.
(FR)
Le procédé de distillation sous vide de l'invention consiste à diviser le produit liquide acheminé jusque dans une cuve sous un vide dans une phase vapeur/gaz ainsi qu'au moins une fraction liquide, à extraire la phase vapeur/gaz de la cuve à l'aide d'un dispositif produisant un vide, et à diviser ensuite la phase vapeur/gaz en une phase gazeuse et une phase liquide par condensation directement dans le dispositif produisant le vide. Une partie de la phase liquide est utilisée en tant que liquide de travail destiné au dispositif produisant le vide. L'installation de distillation sous vide de l'invention comprend une cuve à vide dotée de conduits ainsi qu'un dispositif produisant un vide comportant une soufflante à jet, un séparateur et une pompe, ces éléments étant reliés mutuellement par des conduits.
