Typical Nonthermal Plasma Diagram

Oxides of nitrogen and sulfur have been linked to a broad range of air pollution problems including acid rain and the atmospheric production of photochemical ozone. Efforts to control NOx emissions have lagged because of the generally low discharge concentrations of nitrogen oxides in combustion exhaust and because nitric oxide (NO), the major constituent in combustion-produced NOx is difficult to remove due to its low reactivity.

Electrical discharge techniques are emerging as successful methods for converting gaseous pollutants, such as NOx into inert or treatable species. Chemical reactions are initiated by the interaction of molecules with energetic electrons or photons. These electrons and photons can be produced in any number of ways, including the use of lasers and electrical discharges. Non-thermal plasma methods are particularly useful in pollution control where concentrations at the parts per million level are involved.
