  • Patent number: 7105146
    Abstract: An improved system for slaking of lime which does not rely on the weighing of materials delivered to the vessel where the mixing takes place. A control system is utilized to control the volume of lime and water delivered to insure that a preselected temperature is obtained during the chemical reaction in the vessel. In a batch process the volume of lime and water is controlled based on the temperature sensed to maintain the temperature at the desired level. Once the reaction is complete the resultant slurry is discharged from the vessel for further processing. The vessel is then cleansed and prepared for the next batch.

  • Patent number: 7067107
    Abstract: A steam reforming furnace has a plurality of substantially vertical reformer tubes. Each reformer tube has a feed inlet at its lower end, an outlet at its upper end, and a catalyst containment zone disposed intermediate its upper and lower ends and contains a charge of a particulate steam reforming catalyst which is insufficient to fill completely the catalyst containment zone. An upper retainer means is mounted at the upper end of the catalyst containment zone and is permeable to gas or vapor but retains particles of the catalyst in the catalyst containment zone. A follower means is movably mounted in the catalyst containment zone beneath the charge catalyst for movement upwardly from a lower end of the containment zone upon upward flow of gas through the catalyst containment zone at a rate beyond a threshold rate.

    Abstract: A solid detergent dispenser for use with a dishwashing machine includes a chamber and a lid. The chamber is configured and arranged to receive a solid detergent having a particular composition. A water inlet receives water from a water source, and the water flows through a tunnel into the bottom of the chamber. The chamber is flooded with water from the bottom to ensure relatively constant erosion of the solid detergent, which ensures that a relatively constant concentration of the solid detergent is used in the dishwashing machine. A water outlet allows water to flow out of the chamber into the dishwashing machine. The water must flow into the chamber faster than it flows out of the chamber to ensure that the appropriate amount of dissolution of the solid detergent occurs. The only valve used in the preferred embodiment is a valve to control the amount of water flowing into the water inlet.

    Abstract: The raw syngas generated in a partial oxidation gasifier also includes carbon soot which is removed and recovered from the syngas by scrubbing with water. The scrubbing water contains one or more high temperature surfactants which allow greater soot concentrations in the water-scrubbing quench zone of the gasifier. The carbon soot is separated from the scrubbing water with the aid of a scrubbing oil. The separation of the carbon soot from the scrubbing water is enhanced with the aid of one or more surfactants that render the soot particles hydrophobic and oleophilic. The recovered carbon soot is ultimately recycled to the gasifier to recover the energy value of the carbon during the partial oxidation reaction. The overall energy efficiency of the gasification process can be increased by removing all or a significant portion of the water from the soot mixture before recycling the soot.

  • Publication number: 20030044332
    Abstract: A fluid contactor is taught for mixing and reacting of fluids. Mixing is enhanced by providing a suitable residence time and suitable surface area contact by forming eddy flow within the fluid and thereby the formation of vortexes. Such a contactor does not require the use of mechanical mixers. The contact chamber of the present invention can enhance chemical modification by use of chemical modifiers such as ultraviolet lamps, by allowing the positioning of such modifiers adjacent the vortexes.

  • Publication number: 20030012713
    Abstract: The invention relates to a device for the transfer between a solid matter and a liquid, comprising an outer drum (1) and a perforated inner drum (2), means (4-5) for commonly rotating the drums (1 and 2), and means (18) situated inside the inner drum (2) for moving the solid matter (10). In between the two drums (1 and 2), a number of troughs (21) are formed which, during the rotation of the drums (1 and 2), bring up liquid (8) and pour it out higher up through the inner drum (2). Along the front rim of each trough (21), the drum (2) is provided with a drain opening (23), opposite to which means (24;26) are provided for preventing, when the drain opening (23), during the rotation of the drums (1-2), is at the bottom, the penetration of solid matter (10) through said opening.

  • Patent number: 6468489
    Abstract: The apparatus comprises a NOX reducing unit, a duct to receive a flue gas stream from said NOX and reducing unit, and an activation source associated with the duct. In use, the activation source applies energy to the flue gas stream to facilitate the removal of contaminants from the flue gas stream. Further, the method comprises providing an activation source is downstream of a NOX reducing unit. The activation source is then activated to facilitate the removal of contaminants from the flue gas stream.

  • Patent number: 6399032
    Abstract: The plant for continuously regenerating foundry sand comprises a combustion chamber, in which a combustible gas is added to the sand, and a cooling chamber, in which the sand coming from the combustion chamber is cooled, both chambers being provided with systems for maintain the sand in a fluidized state. The chambers are also in direct communication with one another in the manner of communicating vessels in such a way that, during normal operation in equilibrium, the free surface of the sand may be at the same level in the two chambers.

  • Patent number: 6375903
    Abstract: The synthesis of arrays of DNA probes sequences, polypeptides, and the like is carried out using a patterning process on an active surface of a substrate. An image is projected onto the active surface of the substrate utilizing an image former that includes a light source that provides light to a micromirror device comprising an array of electronically addressable micromirrors, each of which can be selectively tilted between one of at least two positions. Projection optics receives the light reflected from the micromirrors along an optical axis and precisely images the micromirrors onto the active surface of the substrate, which may be used to activate the surface of the substrate. The first level of bases may then be applied to the substrate, followed by development steps, and subsequent exposure of the substrate utilizing a different pattern of micromirrors, with further repeats until the elements of a two dimensional array on the substrate surface have an appropriate base bound thereto.

  • Publication number: 20020025462
    Abstract: A metal hydride is supplied into a reactor while being converted into fine particles. By injecting water from an injector, the metal hydride is hydrolyzed to generate hydrogen. The water supplied to the reactor is water generated by a fuel cell. This allows omission or a size reduction of a water tank for the hydrolysis, and therefore allows a size reduction of the system as a whole. It is possible to adopt a construction in which waste heat from the fuel cell is supplied to pyrolyze the metal hydride, a construction in which heat generated by the hydrolysis is used to pyrolyze another metal hydride, etc.

  • Patent number: 6346221
    Abstract: A waste tire processing apparatus (10) reacts waste tires (26) with a molten reactant metal (19) to recover primarily carbon and stainless steel. The apparatus (10) includes a tire positioning arrangement (20) for positioning the waste tires (26) in the molten reactant metal (19) for a reaction period. After the reaction period, the tire positioning arrangement (20) removes from the molten metal non-reacted solids remaining after the reaction. The non-reacted solids comprise primarily stainless-steel included in the waste tires. As the waste tires (26) are reacted in the molten reactant metal (19), a gas recovery arrangement (14) collects process gases released from the molten metal. The gas recovery arrangement (14) recovers primarily carbon, metal salts, hydrogen, and nitrogen.
