Flue Gas Chemistry

Studies of flue gas chemistry for reducing emissions of pollutants have led to the development of several technologies capable of removing nitrogen oxides, sulfur dioxide, and mercury from power plant emissions.

• PhoSNOX: Yellow Phosphorous for Flue Gas Scrubbing
  (U.S. patent 5,164,167)
• Clamping Down on Mercury Emissions
  (U.S. patent pending)
• Catalysts for Direct Reduction of SO₂ to Elemental Sulfur
  (U.S. patent 5,494,879 and 6,297,189 B1)
