Abstract:
1. A method for deasphalting a hydrocarbon comprising: heating a hydrocarbon comprising about 100 ppmw to about 1,000 ppmw heavy metals to a first temperature of about 50° C. to about 600° C.; pressurizing the hydrocarbon comprising about 100 ppmw to about 1,000 ppmw heavy metals to a first pressure of about 300 kPa to about 3,000 kPa; depressurizing the pressurized hydrocarbon comprising about 100 ppmw to about 1,000 ppmw heavy metals to separate at least a portion of the hydrocarbon to provide a vaporized hydrocarbon mixture and a residual hydrocarbon comprising one or more asphaltenes; mixing the residual hydrocarbon with a solvent to provide a first mixture; heating the first mixture to a second temperature; and separating the asphaltenes from the first mixture to provide a first product comprising a deasphalted oil and at least a portion of the solvent and a second product comprising the asphaltenes and the remaining portion of the solvent.
