  • Patent number: 11407955
    Abstract: A method of agglomerating fine particles such as ultrafine coal in a beneficiation process, uses a water in oil emulsion to significantly reduce the amount of oil needed compared with known oil in water emulsions. A solution of oil and emulsifying agent is provided to which water is progressively added forming a concentrated water in oil emulsion with stabilized water drops (1) packed inside the oil solution phase (2). Fine particles in a slurry are then added, causing the fine particles to collide and stick to the emulsion particles. An optional form of the invention coats tiny portions of the emulsion in a thin film of low viscosity oil (5) to achieve a higher level of selectivity.

  • Patent number: 11407954
    Abstract: A method of preparing a fuel composition includes placing coal having a heat content between about 3,000 BTU/lb and about 9,000 BTU/lb and a moisture content between about 20 wt % and about 60 wt % in a vessel. The coal is exposed to heat and a pressure less than atmospheric pressure within the vessel, thereby reducing the coal, such that an average primary particle size of the coal is less than 1 millimeter. A binder is introduced to the vessel, such that the coal combines with the binder to yield a mixture. The mixture is shaped to yield a fuel composition.

  • Patent number: 11400458
    Abstract: According to the invention, there is provided a process for the beneficiation of coal discards by increasing calorific value and carbon content while removing inert mineral matter and sulphur compounds. The process involves the pretreatment of wash water with a non-ionic kinetically energized surface-active agent and the admixture with a fixed mass of raw coal discard to enhance hydrophobicity and carboniferous particle agglomeration. Processing of the resulting suspension though a dedicated series of spiral separators and high frequency, resonance sieves reliably reduces excessive levels of mineral ash and sulphur compounds.

  • Patent number: 11396635
    Abstract: The present invention provides a method and apparatus for agglomerating hydrophobic particles from a feed slurry. The method comprises adding a binder to a feed stream and conveying the feed stream and binder to an agglomerating device. The binder comprises 50% or more by volume of a non-hydrophobic substance. A high shear is applied to the feed stream and the binder in the agglomerating device to cause the hydrophobic particles to collide and bind to the binder, thereby agglomerating the hydrophobic particles. The agglomerated hydrophobic particles and the binder are removed from the feed stream. A method and apparatus for dewatering an agglomerated product is also provided, the agglomerated product comprising agglomerated hydrophobic particles held together by a binder comprising 50% or more by volume of a non-hydrophobic substance.

  • Patent number: 11396631
    Abstract: A process for preparing a base oil from a waxy hydrocarbon feedstock is provided. The process comprises passing the hydrocarbon feedstock to a distillation column prior to dewaxing in order to recover a heavy wax cut. The heavy wax is then hydrocracked to lower boiling compounds which can be better isomerized to a base oil with an acceptable cloud point. The base oil yield is also increased.

  • Patent number: 11390820
    Abstract: Naphtha boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. The resulting naphtha boiling range fractions can have a high naphthenes to aromatics weight ratio, a low but substantial content of aromatics, and a low sulfur content. In some aspects, the fractions can be used as fuels and/or fuel blending products after fractionation with minimal further refinery processing. In other aspects, the amount of additional refinery processing, such as hydrotreatment, catalytic reforming and/or isomerization, can be reduced or minimized. By reducing, minimizing, or avoiding the amount of hydroprocessing needed to meet fuel and/or fuel blending product specifications, the fractions derived from the high naphthenes to aromatics ratio and low sulfur crudes can provide fuels and/or fuel blending products having a reduced or minimized carbon intensity.

  • Patent number: 11384301
    Abstract: Fuel oil compositions, and methods for blending such fuel oil compositions, to enhance initial compatibility and longer term stability when such fuel oil compositions are blended to meet IMO 2020 low sulfur fuel oil requirements (ISO 8217). In one or more embodiments, asphaltenic resid base stocks are blended with high aromatic slurry oil to facilitate initial compatibility such that low sulfur cutter stocks, e.g., vacuum gas oil and/or cycle oil, may be further blended therein to cut sulfur content while maintaining longer term stability. These fuel oil compositions are economically advantageous when used as marine low sulfur fuel oils because greater concentrations of high viscosity resids are present in the final blend.
