AB  - Nitrogen oxides (NOX) and sulfur oxides (SOX) are criteria air pollutants, 
      emitted in large quantities from fossil-fueled electric power plants. Emissions 
      of SOX are currently being reduced significantly in many places by wet scrubbing 
      of the exhaust or flue gases, but most of the NOX in the flue gases is NO, which 
      is so insoluble that it is virtually impossible to scrub. Consequently, NOX 
      control is mostly achieved by using combustion modifications to limit the 
      formation of NOX, or by using chemical reduction techniques to reduce NOX to N2. 
      Low NOX burners are relatively inexpensive but can only achieve about 50% 
      reduction in NOX emissions; selective catalytic reduction (SCR) can achieve high 
      reductions but is very expensive. The removal of NOX in wet scrubbers could be 
      greatly enhanced by gas-phase oxidation of the NO to NO2, HNO2, and HNO3 (the 
      acid gases are much more soluble in water than NO). This oxidation is 
      accomplished by injecting liquid hydrogen peroxide into the flue gas; the H2O2 
      vaporizes and dissociates into hydroxyl radicals. The active OH radicals then 
      oxidize the NO and NO2. This NOX control technique might prove economically 
      feasible at power plants with existing SO2 scrubbers. The higher chemical costs 
      for H2O2 would be balanced by the investment cost savings, compared with an 
      alternative such as SCR. The oxidation of NOX by using hydrogen peroxide has been 
      demonstrated in a laboratory quartz tube reactor. NO conversions of 97% and 75% 
      were achieved at hydrogen peroxide/NO mole ratios of 2.6 and 1.6, respectively. 
      The reactor conditions (500  degrees C, a pressure of one atmosphere, and 0.7 seconds 
      residence time) are representative of flue gas conditions for a variety of 
      combustion sources. The oxidized NOX species were removed by caustic water 
      scrubbing.
