UPGRADING OIL USING SUPERCRITICAL FLUIDS

A method of upgrading oil using supercritical fluids generated by a fuel cell. The process uses supercritical carbon dioxide to control the specific gravity of the oil and supercritical water, the amount of which is controlled to achieve a desired oil/water ratio in processing oils to be upgraded. The process recovers the GHG emission stream from a fuel cell anode exhaust to produce supercritical fluids.
