    摘要： A method of reducing asphaltene and particulate induced fouling during the thermal processing of petroleum oils utilizes resin extracts from HSDP crude oils to disperse and solubilize asphaltenes and disperse inorganic particulate contaminants such as salts and iron oxide. The extracts are essentially maltene fractions which may be separated from the HSDP crude by a process of extraction from a precipitated asphalt fraction using light paraffinic solvents such as n-heptane.

    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.

    摘要： The invention relates to an integrated, continuous process for the removal of organically bound sulfur (e.g., mercaptans, sulfides and thiophenes) comprising the steps of contacting a heavy oil, sodium hydroxide, hydrogen and water at a temperature of from about 380.degree. C. to 450.degree. C. to partially desulfurize the heavy oil and to form sodium sulfide, contacting said sodium sulfide with a transition metal in water to form a transition metal sulfide, sodium hydroxide and hydrogen. The sodium hydroxide is recirculated and the transition metal sulfide is removed. The partially desulfurized, dewatered heavy oil is treated with sodium metal under desulfurizing conditions, typically at a temperature of from about 340.degree. C. to about 450.degree. C., under a hydrogen pressure of at least about 50 psi to essentially desulfurize the oil, and form sodium sulfide. Optionally, the sodium salt generated can be regenerated to sodium metal using regeneration technology. The process advantageously produces essentially sulfur-free product oils having reduced nitrogen, oxygen and metals contents and reduced viscosity, density, molecular weight and heavy ends.
