Claim 16:
17. The system of claim 16, wherein the supercritical carbon dioxide extraction unit comprises:
a carbon dioxide pump configured to pressurize carbon dioxide to a pressure greater than the critical pressure of carbon dioxide to form a pressurized carbon dioxide;
a carbon dioxide preheater configured to heat the pressurized carbon dioxide to a temperature greater than the critical temperature of carbon dioxide to form the supercritical carbon dioxide;
a feedstock pump configured to pressurize the hydrocarbon feedstock to form a pressurized feedstock;
a feedstock preheater configured to heat the pressurized feedstock to form a heated, pressurized feedstock;
an emulsion pump configured to pressurize the product emulsion to form a pressurized emulsion;
an emulsion preheater configured to heat the pressurized emulsion to form a heated, pressurized emulsion; and
an extractor configured to contact the supercritical carbon dioxide with the heated, pressurized feedstock and the heated pressurized emulsion.
