Method of isolating active resins from a high solvency dispersive power (HSDP) crude oil includes providing a HSDP crude oil, deasphalting the HSDP crude oil into at least a deasphalted oil (DAO) fraction and a first asphaltenes fraction, deasphalting the first asphaltenes fraction to isolate active resins from a second asphaltenes fraction, and combining the DAO fraction and the second asphaltenes fraction to form a de-resinated crude. Method of using components isolated from a high solvency dispersive power (HSDP) crude oil includes providing a HSDP crude oil, deasphalting the HSDP crude oil into at least a deasphalted oil (DAO) fraction and a first asphaltenes fraction, deasphalting the first asphaltenes fraction to isolate active resins from a second asphaltenes fraction, and selecting at least one of the DAO fraction, the active resins, or the second asphaltenes fraction for use in a refinery process.

Linvention concerne un procédé disolement de résines actives à partir dun pétrole brut à pouvoir dissolvant et dispersif élevé (HSDP), qui comprend lutilisation dun pétrole brut HSDP, la désasphaltage du pétrole brut HSDP en au moins une fraction huile désasphaltée (DAO) et une première fraction asphaltènes, la désasphaltage de la première fraction asphaltènes pour isoler des résines actives dune seconde fraction asphaltènes, et le mélange de la fraction DAO et de la seconde fraction asphaltènes pour former un pétrole brut dérésiné. Linvention concerne également un procédé dutilisation de composants issus dun pétrole brut à pouvoir dissolvant et dispersif élevé (HSDP), qui comprend lutilisation dun pétrole brut HSDP, la désasphaltage du pétrole brut HSDP en au moins une fraction huile désasphaltée (DAO) et une première fraction asphaltènes, la désasphaltage de la première fraction asphaltènes pour isoler des résines actives dune seconde fraction asphaltènes, et la sélection de la fraction DAO et/ou des résines actives et/ou de la seconde fraction asphaltènes pour une utilisation dans un procédé de raffinage.
