Title (EN) PROCESS AND APPARATUS FOR TWO-STAGE DEASPHALTING
(FR) PROCÉDÉ ET APPAREIL DE DÉSALPHATAGE EN DEUX ÉTAPES
Abstract:
(EN) Solvent deasphalting (SDA) in series is used to extract deasphalted oil from heavier hydrocarbons in series. Instead of stripping the pitch material of solvent in the second stage which can stick in the pitch stripper and inhibit flow, a dryer is used to vaporize solvent for recycle to the second SDA unit and produce pitch solids.
(FR) L'invention concerne un désasphaltage au solvant (DAS) en série qui est utilisé pour extraire de l'huile désasphaltée d'hydrocarbures plus lourds en série. Au lieu d'extraire le matériau de brai de solvant dans la seconde étape, qui peut coller dans l'extracteur de brai et empêcher l'écoulement, un séchoir est utilisé pour vaporiser le solvant afin de le recycler vers la seconde unité de DAS et produire des solides de brai.
