摘要： The present invention relates to a continuous in-situ process for the removal from heavy oils, of organically bound sulfur in the form of mercaptans, sulfides and thiophenes, heteroatoms selected from the group consisting of nitrogen and oxygen and metals selected from the group consisting of nickel, vanadium and iron, comprising the steps of (a) contacting a heavy oil with aqueous sodium hydroxide at a temperature of about 380 to about 450.degree.C for a time sufficient to form sodium sulfide; (b) contacting said sodium sulfide of step (a) with water and a transition metal for a time and at a temperature sufficient to form transition metal sulfide, sodium hydroxide, hydrogen and impurities; and (c) recirculating said sodium hydroxide from step (b) to step (a) and removing said transition metal sulfide and said impurities, wherein said impurities are iron, vanadium and nickel. Optionally, molecular hydrogen may be added in the first step. The present invention is useful in removing organically bound sulfur that has been recognized to be difficult to remove, such as thiophenes. Beneficially, the process also removes other heteroatoms (nitrogen and oxygen) and metals (vanadium, iron, nickel) and reduces asphaltene content (n-heptane insolubles), micro concarbon residue, coke, 975.degree.F fractions, TGA fixed carbon, average molecular weight, density and viscosity.

摘要： The present invention relates to a continuous in-situ process for the removal of organically bound sulfur existing as mercaptans, sulfides and thiophenes comprising the steps of (a) contacting a heavy oil with aqueous sodium hydroxide at a temperature of about 380.degree.C to about 450.degree.C for a time sufficient to form sodium sulfide, and (b) steam stripping the sodium sulfide of step (a) at a temperature sufficient to convert said sodium sulfide to sodium hydroxide and recirculating the sodium hydroxide from step (b) back to step (a) and removing hydrogen sulfide and the metals from the organically bound metal complex of the sodium sulfide to convert it back to sodium hydroxide, in which case the sulfur may be recovered as H2S rather than the metal sulfide. Optionally, molecular hydrogen may be added in the first step. The present invention is useful in removing organically bound sulfur that has been recognized to be difficult to remove, such as thiophenes. Beneficially, the process also removes other heteroatoms (nitrogen and oxygen) and metals (vanadium, iron, nickel) and reduces asphaltene content (n-heptane insolubles), micro concarbon residue, coke, 975.degree.F fractions, TGA fixed carbon, average molecular weight, density and viscosity.

摘要： A process for the aqueous conversion and upgrading of organic resource materials (e.g., oil shale) is carried out by contacting organic resource materials with water, in the absence of externally supplied hydrogen or reducing agents, controlling the temperature in the range from above about 200 DEG C to below the critical temperature of water to maintain a liquid phase,wherein the pressure is the corresponding vapor pressure, for a time sufficient to effect the conversion and upgrading process. Additionally, the contacting may be conducted in the presence of at least one member of the group selected from a brine catalyst, clay catalyst and mixtures thereof.

摘要： A high solvent power (HSP) crude oil is added to a blend of incompatible oils to proactively address the potential for fouling heat exchange equipment. The HSP component dissolves asphaltene precipitates before coking affects heat exchange surfaces. An HSP oil is also flushed through heat exchange equipment to remove any deposits and/or precipitates on a regular maintenance schedule before coking can affect heat exchange surfaces.

摘要： HSP crude oil is used as process stream in crude oil storage tanks to address sludge levels both by cleaning sludge accumulations and preventing any significant sludge build up when used on a regular basis. HSP crude oil is also used to optimize cleaning routines. Making HSP oil easily accessible by providing a designated HSP source will make tank maintenance more efficient and allow refineries to use the advantages of the HSP oil to the maximum extent.

摘要： A device is coupled to a heat exchanger for mitigating fouling by applying a mechanical force to a fixed heat exchanger to excite a vibration in the heat exchange surface and produce shear waves in the fluid adjacent the heat exchange surface while the heat exchanger is in operation. An electromagnetic driven impulse device induces vibration onto heat exchanger tubes and/or an acoustic wave through the liquid service fluid to reduce fouling. The device can be mounted directly onto the outer part or piping and produces acoustical/vibrational modes onto the tube or near the surface of tubes.
