Title (EN) SOLVENT EXTRACTION PROCESS
(FR) PROCEDE D'EXTRACTION AVEC DES SOLVANTS
Abstract:
(EN) A solvent extraction process for separating a heavy hydrocarbon feedstock material into its various component parts. The process comprises the utilization of pressure reduction to enhance the separation and recovery of a deasphalted oil product comprising substantially the lower molecular weight hydrocarbon components present in the original heavy hydrocarbon feedstock material.
(FR) Un procédé d'extraction avec des solvants permet de séparer un hydrocarbure lourd de départ en ses divers composants. Selon le procédé, on utilise une réduction de la pression afin d'améliorer la séparation et la récupération d'une huile désasphaltée qui comprend essentiellement tous les composants hydrocarbures à poids moléculaire réduit présents dans l'hydrocarbure lourd originel de départ.
