    Abstract: A process and system for reducing contaminants contained in a contaminated feedstock comprising mixing the contaminated feedstock with water and at least one of metal scavengers or reactants, to form a feedstock-water-reactant mixture, feeding the mixture under pressure into a hydrothermal purification reactor, wherein the mixture is subject to heat, pressure, and turbulent flow conditions to cause rapid reaction of the inorganic contaminants with the metal scavengers or reactants to form inorganic salts that partition into an aqueous phase and maintaining the temperature, pressure, and turbulent flow conditions of the feedstock-water-reactant mixture for a predetermined space time to prevent the organic portion of the feedstock in the mixture from undergoing a conversion reaction and to form a hydrothermal reactor effluent; and separating the effluent into the aqueous phase containing salts of the inorganic contaminants and an organic phase that contains a lower concentration of inorganic contaminants than the contaminated feedstock.

    Abstract: A high-rate hydrothermal cleanup (HCU) process and system is disclosed for the rapid hydrolysis of renewable oils and reduction of inorganic and organic contaminants, such as salts, minerals, metals, asphaltenes, polymers, and coke precursors in both renewable oils and petroleum fractions. The process and system is characterized by a very short residence time, high-temperature, high-pressure, turbulent flow, hydrothermal operation. The HCU and integrated vapor-liquid separation system and process results in high yields of oil product that contains significantly reduced concentrations of inorganic and organic contaminants. The process may be operated to produce a concentrated clean glycerin byproduct and short-chain and long-chain free fatty acid product streams. The integrated vapor-liquid separation system and process performs at near atmospheric pressure by taking advantage of the water employed in the cleanup process and the energy imparted by the HCU reactor and eliminates the need for vacuum distillation.

    Abstract: A process and system for converting a high-pour-point organic feedstock to an upgraded product that exhibits good low-temperature properties (cloud point, pour point, and viscosity) and improved transportability. The high-efficiency process includes a continuous-flow, high-rate hydrothermal reactor system and integrated separation systems that result in low complexity, small footprint, high energy efficiency, and high yields of high-quality upgraded product. The system is specifically desirable for use in converting waxy feedstocks, such as yellow and black wax petroleum crudes and wax from the Fischer-Tropsch (FT) process, into upgraded crude that exhibits a high diesel fraction and, correspondingly, low vacuum gas oil (VGO) fraction.

    Abstract: A supercritical water separation process and system is disclosed for the removal of metals, minerals, particulate, asphaltenes, and resins from a contaminated organic material. The present invention takes advantage of the physical and chemical properties of supercritical water to effect the desired separation of contaminants from organic materials and permit scale-up. At a temperature and pressure above the critical point of water (374° C., 22.1 MPa), nonpolar organic compounds become miscible in supercritical water (SCW) and polar compounds and asphaltenes become immiscible. The process and system disclosed continuously separates immiscible contaminants and solids from the supercritical water and clean oil product solution. The present invention creates a density gradient that enables over 95% recovery of clean oil and over 99% reduction of contaminants such as asphaltenes and particulate matter depending on the properties of the contaminated organic material.

    Abstract: A process and system for upgrading an organic feedstock including providing an organic feedstock and water mixture, feeding the mixture into a high-rate, hydrothermal reactor, wherein the mixture is rapidly heated, subjected to heat, pressure, and turbulent flow, maintaining the heat and pressure of the mixture for a residence time of less than three minutes to cause the organic components of the mixture to undergo conversion reactions resulting in increased yields of distillate fuels, higher-quality kerosene and diesel fuels, and the formation of high octane naphtha compounds. Hydrocarbon products are cooled at a rate sufficient to inhibit additional reaction and recover of process heat, and depressurizing the hydrocarbon products, and separating the hydrocarbon products for further processing. The process and system can include devices to convert olefinic hydrocarbons into paraffinic hydrocarbons and convert olefinic byproduct gas to additional high-octane naphtha and/or heavier hydrocarbons by one of hydrogenation, alkylation, or oligomerization.
