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 13):
The system of  claim 12 , wherein the petroleum feedstock is a petroleum-based hydrocarbon selected from the group consisting of whole range crude oil, reduced crude oil, fuel oil, refinery streams, residues from refinery streams, cracked product streams from crude oil refinery, atmospheric residue streams, vacuum residue streams, coal-derived hydrocarbons, liquefied coal, bitumen, biomass-derived hydrocarbons, and hydrocarbon streams from other petrochemical processes.
