    Abstract: A tribo-electrostatic separation process and system for the preparation of various food and feed products. A tribo-electric separation process and system for fractionating a feed mixture comprising at least two members of the group of proteins, starches, soluble and insoluble fibers. Namely, supplying a feed mixture comprising at least two of the group of proteins, starches, soluble and insoluble fibers to a tribo-electric separator and simultaneously charging and separating the feed mixture into at least two subfractions, with one of the subfractions enriched in one of protein, starch and fiber and having a composition different than the feed mixture.

  • Publication number: 20210086196
    Abstract: A process for fractionating a feed mixture derived from dried brewer's spent grains (BSG) or distiller's grains (DDG) or distiller's dried grains and mixed with solubles (DDGS) is disclosed. The process includes using a single-step tribo-electrostatic separation process and device to separate the feed mixture by supplying the feed mixture to a tribo-electric separator and simultaneously charging and separating the feed mixture into at least two subfractions, with one of the subfractions having a protein composition higher than the feed mixture and higher than that could be obtained otherwise.

  • Publication number: 20110289923
    Abstract: A method and apparatus for recovering mercury control reagents from particulate materials is disclosed. The particulate materials include fly ash mixed with mercury control reagents collected from boiler flue gases. The particulate materials are provided to an electrostatic separation system, which is operated under predetermined conditions so as to produce a concentrated stream of the mercury control reagent and a diluted stream containing minimal mercury control reagent.

  • Patent number: 6156837
    Abstract: A process for producing carbon blacks comprised of mixing an oxidant, primary fuel, and carbon black feedstock to form carbon black particles and aggregates, passing the mixture through a reactor, cooling, separating, and recovering the carbon black product. The improvement comprises the addition of a secondary oxidant-containing stream to the reactor such that the secondary oxidant stream does not interfere with the formation of the carbon black particles and aggregates in the reactor. Also disclosed are new carbon black products defined by the following parameters:35 mg/g.ltoreq.I.sub.2 No..ltoreq.65 mg/g30 m.sup.2 g.ltoreq.CTAB.ltoreq.55 m.sup.2 g1.12 mg/m.sup.2 .ltoreq.I.sub.2 No./CTAB ratioTint.ltoreq.65%75 cc/100 g.ltoreq.CDBP.ltoreq.95 cc/100 gAlso disclosed are rubber and/or plastic compositions containing the new carbon blacks.

  • Patent number: 6077494
    Abstract: A method for removing ammonia from coal fly ash contaminated by ammonium salts is disclosed. The method involves the addition of small amounts of water, and in some cases, small amounts of an alkali source, to the fly ash to liberate the ammonia trapped therein. The ammonia liberation may be further aided by vigorous mixing of the fly ash.

  • Patent number: 6074458
    Abstract: Apparatus and method for separating carbon particles from flyash includes one of increasing a relative humidity of the flyash or decreasing the relative humidity of the flyash to within an optimum humidity range, and introducing the flyash within the optimum humidity range into a triboelectric separator so as to triboelectrically charge the carbon particles and the flyash and so as to electrostatically separate the charged carbon particles from the charged flyash.

  • Patent number: 5352289
    Abstract: Novel furnace carbon blacks that impart advantageous properties to rubber and plastic compositions and may be utilized in the place of acetylene blacks. The furnace carbon blacks have an ash level less than or equal to 50 ppm, preferably less than or equal to 30 ppm, most preferably less than or equal to 10 ppm, a sulfur level less than or equal to 50 ppm, preferably less than or equal to 30 ppm most preferably less than or equal to 10 ppm, a L.sub.a less than or equal to 30 .ANG. and a L.sub.c less than or equal to 30 .ANG.. Also disclosed are novel rubber and plastic compositions incorporating the novel furnace carbon blacks which exhibit advantageous properties, particularly in extending the useful service life of power cables produced using the compositions.

  • Patent number: 5236155
    Abstract: In the present method boundary layer thickening is combined with laminar flow control to reduce drag. An aerodynamic body is accelerated enabling a ram turbine on the body to receive air at velocity V.sub.o. The discharge air is directed over an aft portion of the aerodynamic body producing boundary layer thickening. The ram turbine also drives a compressor by applying torque to a shaft connected between the ram turbine and the compressor.The compressor sucks in lower boundary layer air through inlets in the shell of the aircraft producing laminar flow control and reducing drag. The discharge from the compressor is expanded in a nozzle to produce thrust.
