  • Oxidation of NOx's with chlorine dioxide in combination with a thermal NOx removal process
    Publication number: 20040131523
    Abstract: A process for reducing NOx concentrations in waste gas streams by contacting the waste gas stream with a reducing agent selected from ammonia and urea and then oxidizing the lower NOx's present in the waste gas streams to higher oxides with chlorine dioxide.
    Type: Application
    Filed: May 1, 2003
    Publication date: July 8, 2004
    Applicant: ExxonMobil Research and Engineering Company
    Inventors: Theresa J. Takacs, Robert G. Balmer, Boyd E. Hurst, William J. McLaughlin, David G. Knight, John D. Cunic, Henry Shaw, Chen-Lu Yang, Pin Gu
  • Selective non-catalytic reduction of NOx
    Publication number: 20040022708
    Abstract: A reducing agent and a readily-oxidizable gas are injected into a NOx-containing process stream to reduce the concentration of the NOx-containing process stream by a predetermined amount.
    Type: Application
    Filed: May 1, 2003
    Publication date: February 5, 2004
    Applicant: ExxonMobil Research and Engineering Company

  • Process for reducing NOx in waste gas streams using sodium chlorite
    Publication number: 20040005263
    Abstract: A process for reducing NOx concentrations in waste gas streams. More particularly, the present invention relates to contacting a NOx-containing waste gas stream with an effective amount of sodium chlorite under conditions such that at least a fraction of the oxidizable NOx species present in the waste gas stream is oxidized to higher nitrogen oxides.
