Summary:The present invention relates to a process for improving a deasphalting unit process by producing an improved feed-stream for the deasphalting process via ultrafiltration of a vacuum resid-containing feedstream. In particular, the present invention produces an improved quality feedstream to a solvent deasphalting process which results in improved deasphalted oil (DAO) produc-tion rates and/or higher quality deasphalted oils. The present invention can be particularly beneficial when used in conjunction with an existing deasphalting equipment to result in improved deasphalted oil (DAO) production rates and/or higher quality deasphalted oils from the existing deasphalting equipment without the need for significant equipment modifications to the existing deasphalting unit. La présente invention concerne un procédé visant à améliorer un processus de désasphaltage en générant un courant d'alimentation amélioré dans le processus de désasphaltage par ultrafiltration d'un courant d'alimentation contenant des résidus sous vide. Cette invention permet de générer, notamment, un courant d'alimentation de meilleure qualité dans un processus de désasphaltage au solvant qui donne lieu à de meilleurs taux de production et/ou à une meilleure qualité des huiles désasphaltées à partir d'un équipement de désasphaltage existant sans avoir à effectuer d'importantes modifications sur ce dernier.
