  • Publication number: 20140341795
    Abstract: Method and apparatus for producing molten purified crystalline silicon from low-grade siliceous fluorspar ore, sulfur trioxide gas, and a metallic iodide salt. Method involves: (1) initially reacting silicon dioxide-bearing fluorspar ore and sulfur trioxide gas in sulfuric acid to create silicon tetrafluoride gas and fluorogypsum; (2) reacting the product gas with a heated iodide salt to form a fluoride salt and silicon tetraiodide; (3) isolating silicon tetraiodide from impurities and purifying it by washing steps and distillation in a series of distillation columns; (4) heating the silicon tetraiodide to its decomposition temperature in a silicon crystal casting machine, producing pure molten silicon metal ready for crystallization; and pure iodine gas, extracted as liquid in a cold-wall chamber. The system is batch process-based, with continuous elements. The system operates largely at atmospheric pressure, requiring limited inert gas purges during batch changes.

  • Patent number: 8871174
    Abstract: Elemental fluorine is used as etching agent for the manufacture of electronic devices, especially semiconductor devices, micro-electromechanical devices, thin film transistors, flat panel displays and solar panels, and as chamber cleaning agent mainly for plasma-enhanced vapor deposition (PECVD) apparatus. For this purpose, fluorine often is produced on-site. The invention provides a process wherein the contamination of the elemental fluorine with gaseous impurities, such as air or moisture, is prevented by producing it on site and delivering it to the point of use under a pressure higher than ambient pressure.

  • Patent number: 8268269
    Abstract: As population density increases, the transportation of hazardous chemicals, including acids and disinfectants, lead to an increased incidence of spills while the consequences of spills become more serious. While solutions of halide acids, hypohalites and halites are safer disinfectants for transportation, handling, storage and use than traditional gaseous chlorine, the manufacturing cost of these disinfectants has here-to-fore limited their use. Economical processes are presented for the manufacture of O2, halogen oxides, halide acids, hypohalites, and halates; as well as polynucleate metal compounds, metal hydroxides and calcium sulfate hydrate (gypsum). The instant invention presents methods and processes that incorporate the use of sulfur. This is while environmental regulators, such as the US EPA, require an increased removal of sulfur from hydrocarbon fuels, thereby creating an abundance of sulfur, such that the refining industry is in need of a way to dispose of said abundance of sulfur.

    Abstract: A system for supplying chlorine to and recovering chlorine from a polysilicon plant may include a brine treatment system, at least one membrane cell, a chlorine drying system, a chlorine compression system, a hydrogen drying system, a hydrogen compression system, a hydrogen chloride synthesis/desorption system, a hydrogen chloride liquefaction system, a liquefied hydrogen chloride storage system, a hydrogen chloride vaporizer, and a waste conversion and filtration system. These systems may be operatively joined to generate hydrogen chloride gas for delivery to the polysilicon plant. A method for supplying chlorine to the polysilicon plant may include generating hydrogen gas and chlorine gas from recovered and raw salt, converting at least a portion of the hydrogen gas and at least a portion of the chlorine gas to hydrogen chloride, passing the hydrogen chloride through a cryogenic column, vaporizing the hydrogen chloride, and providing the vaporized hydrogen chloride to the polysilicon plant.

  • Publication number: 20090042720
    Abstract: The present invention relates to a process for preparing an activating support for metallocene complexes in the polymerisation of olefins comprising the steps of: I) providing a support prepared consisting in particles formed from at least one porous mineral oxide; II) optionally fixing the rate of silanols on the surface of the support; III) functionalising the support with a solution containing a fluorinated functionalising agent; IV) heating the functionalised and fluorinated support of step c) under an inert gas and then under oxygen; V) retrieving an active fluorinated support. That activating support is used to activate a metallocene catalyst component for the polymerisation of olefins.

  • Publication number: 20080241040
    Abstract: Crystalline scintillator materials comprising nano-scale particles of metal halides are provided. The nano-scale particles are less than 100 nm in size. Methods are provided for preparing the particles. In these methods, ionic liquids are used in place of water to allow precipitation of the final product. In one method, the metal precursors and halide salts are dissolved in separate ionic liquids to form solutions, which are then combined to form the nano-crystalline end product. In the other methods, micro-emulsions are formed using ionic liquids to control particle size.

  • Publication number: 20080210444
    Abstract: Methods of reducing smoke levels in smoke-affected areas, reducing the level of toxic compounds produced by fires, fire suppression, and increasing flame retardancy. In particular, methods according to the present invention comprise dispersing nanocrystalline particles in the areas affected by smoke for sorption of smoke particulates and toxic compounds produced from a fire. The nanocrystalline particles are also effective for use in methods of fire suppression and flame retardancy.

  • Publication number: 20080152579
    Abstract: The invention is a method of producing stable chlorous acid for use as a cleaning agent and biocidal composition. The method passes a salt of an oxy-chloro acid over a resin to allow for an ion exchange that produced the oxy-chloro acid. The invention allows for the production of a stable chlorous acid that can be used as a biocidal agent and a cleaning agent without the effect on many surfaces or membranes as normal oxy-chloro compositions.
