  • Patent number: 8576397
    Abstract: The invention relates to a method for determining a gas concentration in a flowing gas mixture, wherein the flowing gas mixture includes solids having a defined size distribution, wherein by way of an optical spectrometer the concentration of a gas is measured in the flowing gas mixture, which includes a measurement beam of the optical spectrometer being conducted during the measurement through a measurement channel having walls made of a gas-permeable material. The invention also relates to a device for carrying out such a method.
    Type: Grant
    Filed: February 17, 2012
    Date of Patent: November 5, 2013
    Assignee: Wacker Chemie AG
    Inventors: Markus Kerschhacker, Johann Huber, Markus Niemetz, Christoph Maurer

  • Patent number: 7803342
    Abstract: Highly pure pyrogenic silica is produced in an integrated polycrystalline silicon production plant by separating offgas from polycrystalline silicon production into a high boiler fraction, vaporizing this fraction into a pyrogenic silica burner and reacting with air and/or oxygen and hydrogen to form pyrogenic silica.
