And Indirect Contact Heating Fluid Means In Separating Or Dissolving Chamber Patents (Class 422/290)
  • Patent number: 7811416
    Abstract: Provided is an apparatus for digesting cellulosic material that includes a vessel containing a digestion chamber and having an opening that provides access to the digestion chamber. A container for holding the cellulosic material is located within the digestion chamber. A closure interfaces with the vessel opening to form a seal against a predetermined digestion pressure and temperature within the chamber. A fluid-transporting system directs digestion fluids from a supply in the digestion chamber through a port and the container toward any cellulosic material therein. Digestion fluid distributed from the port through the container soaks the cellulosic material. Also provided are processes for digestion cellulosic material.

  • Patent number: 5573740
    Abstract: Phosphine is generated by the reaction of water with a metal phosphide formulation. In one embodiment, the formulation is within a housing closed by a membrane which is permeable to water and phosphine. A water-containing gas flows across the membrane and water from the gas permeates into the housing to react with the phosphide, producing phosphine which also permeates through the membrane to enter the gas flow. Two membranes may be used to close the housing, one permeable to water, the other permeable to phosphine. A blanking plate and phosphine absorber may be included to control the phosphine production. In a second embodiment, pellets of a phosphide formulation are transferred, periodically, from a hopper to a chamber containing water. The transfer is effected by a disc member mounted below the hopper and above the chamber. The disc member has at least one aperture in it, within which pellets are transported from the hopper outlet to an inlet port of the chamber.

  • Patent number: 5275793
    Abstract: The present invention describes a method and apparatus in which solid gelatin chunks are liquefied, tempered, and debubbled in a single operation. The debubbling step is accomplished by evacuating and sealing off the loaded solid reservoir and heat exchanger before initiating the liquefying step. After the vacuum is applied, the gelled chunks are pressed into the heat exchanger, where heat is applied to the gelled chunks of photographic material. This liquefies the gelled chunks of photographic material. When the liquefied product gives a positive pressure at the heat exchanger outlet, the liquefied product is allowed to flow from the heat exchanger. Liquefying and tempering are performed as the solid chunks are pushed through the heat exchanger by the reservoir piston.

  • Patent number: 5114540
    Abstract: An apparatus for chemical treatment of lignocellulosic materials comprises two concentric compartments, the inner one is used for chemical reaction whereas the outer is used for generation of hot water or steam. The top and the bottom of the outer compartment is closed and connected to the inner one. These two are interconnected by two steam conduits. The inner compartment is also connected to a circulation pump and a heat exchanger. The bottom of this inner compartment is equipped with a quick-release valve which may be used to execute explosive discharge of the treated lignocellulosic material. On top of said apparatus is a cover which allows experiments to be performed under pressurized conditions. For experimentation, lignocellulosic material in form of chips (large particles) may be treated either with heated chemical solution or steam. Materials in form of fibers (fine particles) may be treated by means of vapor or by heat conduction furnished by the outer compartment.

  • Patent number: 4946739
    Abstract: This invention is directed to an enamel paint receptive flexible laminate and its method of manufacture. The laminate is useful for making banners, flags, signs and the like that are decorated with enamel poster paints. The laminates of the present invention comprise a base fabric material, a first film coating of a plasticized polyvinyl chloride and a second coating of thermosetting vinyl acrylic copolymer. The thermosetting vinyl acrylic copolymer promotes increased adhesion and decreased drying time of poster paints and lettering enamel when they are applied to the coating.

  • Patent number: 4670222
    Abstract: A high pressure reaction vessel has a container portion and a removable head portion which houses a flow channel or channels, valve members and valve operators and which seals and covers the container portion. Each channel terminates at a tapered valve seat angled at at least with respect to the horizontal and each of the valve members is provided with a mating tapered surface which is wedged more tightly within the valve seat as pressure within the vessel increases. A port and a chute are provided for introducing a particulate solid feed through at least one of the channels into the interior of the vessel. In one embodiment a dip tube depends from a second valve seat (in communication with a second channel) and extends to a point adjacent the bottom of the container portion.

  • Patent number: 4608175
    Abstract: This invention is a sanitary disposal system for human waste and organic garbage by aerobic composting combined with solar evaporative distillation for greywater. The aerobic composting reduces waste volume by ninety percent leaving water, carbon dioxide and a harmless but fertile ash by-product. Except for urine, the system essentially operates dry. No chemicals, septic system, or sewage treatment plant is required. There is no odor and no polluting discharged during operation. A nonsoiling toilet seat is provided so a dry toilet bowl may be used without the usual problems of cleaning. Insects are prevented from entering or leaving the system which is constantly aerated to assure that the composting process does not convert to anaerobic. The greywater system further enhances pollution control. This includes solar evaporative distillation to separate out solids which can be disposed of in a sanitary dump while the reclaimed water can be used for non-household purposes.

  • Patent number: 4587373
    Abstract: Disclosed is a method and apparatus for the recovery and/or recycling of dimethylether (DME) during a methanol-to-chemical (MTC) conversion reaction. The hydrocarbon output is divided into liquid, vaporous and aqueous products. The liquid hydrocarbon products are reboiled to liberate dissolved DME and then provided as a liquid hydrocarbon product output. Vapor products resulting from the reboiling are combined with the vapor hydrocarbon stream and DME is removed therefrom in a DME absorber. The resultant vaporous hydrocarbons are passed out of the system as a product and the DME absorber materials recycled. In one embodiment, the DME absorber materials are methanol and water and these are combined with the aqueous liquid stream, stripped to reduce the water content, and resubmitted to the MTC reaction section for conversion.

  • Patent number: 4375387
    Abstract: Process and apparatus for extracting an organic liquid from an organic liquid solute/solvent mixture. The mixture is contacted with a fluid extractant which is at a temperature and pressure to render the extractant a solvent for the solute but not for the solvent. The resulting fluid extract of the solute is then depressurized to give a still feed which is distilled to form still overhead vapors and liquid still bottoms. The enthalpy required to effect this distillation is provided by compressing the still overhead vapors to heat them and indirectly to heat the still feed. The process is particularly suitable for separating mixtures which form azeotropes, e.g., oxygenated hydrocarbon/water mixtures. The energy required in this process is much less than that required to separate such mixtures by conventional distillation techniques.
