Abstract:
A method to remove a metals impurity from a petroleum feedstock for use in a power generating process is provided. The method comprising the steps of mixing a heated feedstock with a heated water stream in a mixing device to produce a mixed stream; introducing the mixed stream to a supercritical water reactor in the absence of externally provided hydrogen and externally provided oxidizing agent to produce a reactor effluent comprising a refined petroleum portion; cooling the reactor effluent to produce a cooled stream; feeding the cooled stream to a rejecter configured to separate a sludge fraction to produce a de-sludged stream; reducing the pressure of the de-sludged stream to produce a depressurized product; separating the depressurized product to produce a gas phase product and a liquid product; separating the liquid product to produce a petroleum product, having a reduced asphaltene content, reduced concentration of metals impurity, and reduced sulfur.

Claim (Index 12):
A system to remove a metals impurity from a petroleum feedstock for use in a power generating process, the system comprising:\n a mixing device, the mixing device configured to produce a mixed stream from a heated feedstock and a heated water stream, the heated feedstock comprising the metals impurity,\n wherein the mixed stream comprises an asphaltene and resin portion, a hydrocarbon portion, and a supercritical water portion, wherein the mixed stream is at a temperature less than 400 deg C; \n a supercritical water reactor, the supercritical water reactor fluidly connected to the mixing device, the supercritical water reactor in the absence of externally provided hydrogen and externally provided oxidizing agent and configured to produce a reactor effluent, the reactor effluent comprising a refined petroleum portion, converted metals, and an amount of solid coke, wherein demetallization reactions and a set of conversion reactions occur in the supercritical water reactor, wherein the demetallization reactions are operable to convert the metals impurity to converted metals, wherein the set of conversion reactions is operable to refine the hydrocarbon portion in the presence of the supercritical water portion to produce the refined petroleum portion; a cooling device, the cooling device fluidly connected to the supercritical water reactor, the cooling device configured to cooling the reactor effluent to produce a cooled stream, wherein the cooled stream is at a temperature below the critical temperature of water; a depressurizing device, the depressurizing device fluidly connected to the cooling device, the depressurizing device configured to reduce the pressure of the cooled stream to produce a depressurized stream, wherein the depressurized stream comprises the refined petroleum portion, an asphaltene fraction, a water fraction, and a gas phase product fraction; a gas-liquid separator, the gas-liquid separator fluidly connected to the depressurizing device, the depressurizing device configured to separate the depressurized stream to produce a gas product and a liquid phase stream; an oil-water separator, the oil-water separator fluidly connected to the gas-liquid separator, the oil-water separator configured to separate the liquid phase stream to produce a liquid-phase petroleum stream and a water phase stream; a solvent extractor, the solvent extractor fluidly connected to the oil-water separator, the solvent extractor configured to extract a petroleum product from the liquid-phase petroleum stream to leave a metal-containing fraction, the petroleum product having reduced asphaltene content, reduced concentration of metals impurity, and reduced sulfur as compared to the petroleum feedstock.
