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
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.
