摘要： A process for producing aromatics from a hydrocarbon source in the presence of supercritical water comprising the steps of mixing a pressurized, pre-heated water stream with a pressurized, pre-heated petroleum feedstock, the pressurized, pre-heated water stream at a pressure above the critical pressure of water and a temperature above the critical temperature of water, feeding the combined stream to a supercritical water reactor to create a modified stream, cooling and depressurizing the modified stream, separating the depressurized stream in a vapor-liquid separator, condensing the vapor stream, separating the condensed stream into a water recovery stream and a light product recovery stream, extracting the aromatics from the light product recovery stream, depressurizing the liquid stream, separating the depressurized liquid stream in a heavy separator into an upgraded product stream, and recycling part of the upgraded product stream to the pressurized, pre-heated petroleum feedstock as a product recycle.

摘要： 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.

摘要： Embodiments of the disclosure provide a system and method for producing light olefins from a crude oil. A crude oil feed is introduced to a crude distillation unit to produce a distillate fraction and a residue fraction. The distillate fraction is introduced to a non-catalytic steam cracker to produce a light olefin fraction and a pyrolysis oil fraction. The residue fraction is introduced to a supercritical water reactor to produce an effluent stream. The effluent stream is introduced to a flash separator to produce a gas phase fraction and a liquid phase fraction. The gas phase fraction is introduced to a catalytic steam cracker to produce a light olefin fraction and a pyrolysis oil fraction. Optionally, the residue fraction is introduced to a vacuum distillation unit to produce a light vacuum gasoil fraction, a heavy vacuum gasoil fraction, and a vacuum residue fraction. The vacuum residue fraction is introduced to a solvent deasphalting unit to produce a deasphalted oil and a pitch fraction. The deasphalted oil fraction, optionally combined with the heavy vacuum gasoil fraction, can be introduced to the supercritical water reactor in lieu of the residue fraction.
