Abstract:
Systems and methods for deasphalting a hydrocarbon are provided. A hydrocarbon can be heated to a first temperature and pressurized to a first pressure. The pressurized hydrocarbon can be depressurized to separate at least a portion of the hydrocarbon to provide a vaporized hydrocarbon mixture and a residual hydrocarbon that can include asphaltenes. The residual hydrocarbon can be mixed with a solvent to provide a first mixture. The first mixture can be heated to a second temperature. The asphaltenes can be separated from the first mixture to provide a first product and a second product. The first product can include a deasphalted oil and at least a portion of the solvent. The second product can include the asphaltenes and the remaining portion of the solvent.
