  • Publication number: 20140101968
    Abstract: A method for removing a moistening liquid from a moistened medium includes providing a liquid-blocking barrier having a first surface and a second surface that is impermeable to a heating liquid. A surface of the moistened medium is brought into contact with the first surface of the liquid-blocking barrier. The heating liquid is brought into contact with the second surface of the liquid-blocking barrier, the heating liquid being at a temperature greater than a moistening-liquid boiling point. Heat is thus transferred through the liquid-blocking barrier from the heating liquid to the moistening liquid, vaporizing the moistening liquid and removing it from the moistened medium.

  • Publication number: 20140068963
    Abstract: A process for reducing the cost associated with the transportation and disposal of waste material by extracting water ad other liquids from municipal solid waste, construction and demolition debris, and putrescible waste to thereby significantly reduce the weight of the material prior to transport. In one embodiment, the process involves waste product being turned through a heated auger system, wherein the waste material is indirectly heated by high temperature oil to remove the liquid (including water) and moisture content from the waste product. In another embodiment, the process involves manual or automated movement of the waste material through an environmentally contained area that houses heating devices (e.g., heat lamps) for simulating sunlight, fans, and a water purification and filtration system for drying the waste material and delivering the water content to the water filtration and purification system.

  • Patent number: 8056258
    Abstract: A cord drying apparatus dries cords for forming cord-inserted bands, such as belts and components of tires, such as carcasses. A plurality of cords C unwound from a plurality of reels 1a held in a wheeled creel 1 are passed through guide holes formed in a guide plate 21 and are extended to an insulation head 6. Vertically movable rollers 4 are moved down from their home positions above the cords C to cause the cords C to extend along curved heating surfaces of heating boards 5. The cords C are moved along the heating surfaces of the heating boards 5 to dry the cords C. The cords C can be easily extended along and pressed against the heating surfaces of the heating boards 5. Thus cords C can be changed in a short time and the efficiency of operations for drying cords C by a drying process can be improved.

    Abstract: A new Indirectly Heated Screw Processor Apparatus and Methods wherein a series of rotating helical ducts or hollow flites radial to a shaft, transfers heat via a heat transfer medium, the first face flite disc facing in the opposite direction to material or product flow and thereby significantly increasing the product retention time and thermal heat transfer. Heat is transferred via a heat transfer medium through a rotary joint to the inner surface of the hollow shaft. The flites continuously traverse a longitudinal portion of the rotor wherein said flites are equally spaced apart in a substantially parallel angle and orientation, the spacing, or pitch, concluding in a non-flite, or “dead zone” region of the longitudinal length of rotor wherein the material or product accumulates and is retained for an increased amount of time, and when compared to conventional indirect-heating screw conveyors, the apparatus provides a higher percentage of flite height fill.

  • Patent number: 6829844
    Abstract: Treatment apparatus and a process for thermal desorption of hydrocarbon contaminants from excavated soil provides efficient contaminant removal by handling the soil in a thermally conductive treatment vessel that fits within an insulated treatment chamber. The soil is treated in this chamber with fresh air that is dried and electrically heated prior to contacting the treatment vessel. The dry air passes through the soil and the air mixed with contaminants is withdrawn from the chamber through piping in the treatment vessel. Excavating the soil directly into the treatment vessel allows the treated soil to be returned to the final disposition site in the same vessel, minimizing soil handling.

  • Patent number: 5887514
    Abstract: The invention relates to a method, a press, and a control device for reducing the capillary-bound water content in fiber cells of carbon-containing, finely comminuted solid materials and/or sludges. The method according to the invention includes rapidly raising the movable press plate of a filter press while the pressure chamber remains closed. A steam-coal dust mixture is formed due to the rapid expansion. At the same time, a first discharge lock is opened while the second discharge lock remains closed so that the exhaust steam flows in the direction of the controlled outlet valve. The exhaust steam can then be sent to a heat exchanger and then to another heat exchanger and, finally, may be reused for a subsequent operating cycle.

    Abstract: Water content which is bound by capillarity in fiber cells of carboniferous materials is reduced by a thermomechanical dewatering process. In the process, the carboniferous materials are conveyed by a dispersion box into a pressure chamber including upper and lower plates. Steam is applied to the materials introduced into the pressure chamber from both the upper and lower plates to heat the materials up to about 125.degree. C. and to release the water which is bound by capillarity in the fiber cells. Initially, the pressure within the chamber is maintained at no greater than the steam pressure. Subsequently, the pressure chamber is sealed gastight and the carboniferous materials in the pressure chamber are pressed using the upper and lower plates.

  • Patent number: 5529696
    Abstract: A method of laundering oily items comprises laundering said items in a wash solution which includes a surfactant system and a source of alkalinity. The source of alkalinity is an alkali metal aluminate preferably sodium aluminate at a concentration effective to have at least about 25 ppm of the alkali aluminate present in the wash solution measured as alumina. The wash solution is then separated from the laundered items and its pH reduced to about 9 or less. A destabilizing polymer such as diallyldimethyl ammonium chloride can be added. This combination causes the oil and grease to separate from the wash solution and float to the surface along with the sodium aluminate. If the concentration of the sodium aluminate is above about 100 ppm preferably about 250 ppm, there is no need to add the destabilizing polymer. This does not affect the overall efficiency of the detergent, yet significantly improves the ability to separate the oil and grease from the waste wash solution.
