  • Patent number: 10941335
    Abstract: A fines-fixing agent that has improved compatibility with organic complexed borate fracturing fluids is disclosed. Existing fines fixing agents have a high concentration of unreacted caustic that results in a product pH of approximately 12. This high pH affects the crosslinker and the overall fracturing fluid system stability, promoting precipitation of the organic crosslinker. These effects can be mitigated by neutralizing the fines fixing agents with an acid such as hydrochloric or acetic acid to a pH of 6 or lower.

  • Patent number: 10941337
    Abstract: Suspension of proppants in hydraulic fracturing applications can be strongly affected by the cross-sectional shapes and lengths of the fibers present in the wellbore treatment compositions. For instance, it has been observed that crimped cellulose ester fibers with a trilobal cross-section and an optimized length can provide enhanced suspension of proppants in aqueous fracturing fluids. Furthermore, the present invention demonstrates that non-round cellulose ester fibers can provide superior proppant suspension properties relative to polylactic acid fibers with a round cross-section.

  • Patent number: 10941355
    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.

  • Patent number: 10941358
    Abstract: The present invention describes a method for refining highly polyaromatic and nitrogenated charges, such as LCO streams, comprising hydrotreating (HDT) as the first reaction stage, followed by the intermediate separation of gases generated in the HDT section, then by a second reaction stage consisting in moderate hydroconversion/hydrocracking and in a rectifying and/or fractionating section, thus allowing more flexible production of fuels. In the rectification mode, the claimed method yields a diesel oil fraction with higher cetane content, reduced density and volumetric yield increase of at least 111% relative to the process charge, thus minimising yield losses through naphtha overcracking and contributing to the optimisation of the required hydrogen consumption. In the fractionating mode, different cuts and their compositions can be produced, such as naphtha, kerosene and diesel.

  • Patent number: 10941365
    Abstract: A method is provided for producing a solid fuel to be used as fuel for a pulverized coal boiler from wood biomass as a source material at a high mass yield and calorie yield by performing a grinding treatment in a mixture with coal. A solid fuel is produced by adjusting the moisture of a ground powder of wood biomass to between 8 and 50%; densifying the ground powder of wood biomass to a bulk density of 0.55 g/cm3 or higher (measured according to JIS K 2151-6 “Bulk density test method”); and then subjecting the ground powder of wood biomass to torrefaction under conditions of an oxygen concentration of 10% or less and a temperature between 170 and 350° C. Since the bulk density of a source material is high, a trouble in conveyance such as clogging of a rotary valve at an inlet of a carbonization furnace, or clogging of a cyclone after a drier due to excessive reject can be prevented.
