  • Process for production and use of deactivated gaseous atomic nitrogen for post combustion gas nitric oxide emissions control
    Patent number: 5547651
    Abstract: A process for nitric oxide (NO.sub.x) emissions reduction and post combustion gases at power plants and industrial boilers. The process deactivates nitrogen gaseous atoms which react with the nitric oxide to form N.sub.2 +O(.sup.3 P). The process reduces the NO which is nitric oxide. The oxygen atom by itself reacts with carbon monoxide (CO) to become carbon dioxide (CO.sub.2). The N.sub.2 nitrogen atom simply becomes part of air. Therefore, the process reduces not only the nitric oxide, but also carbon monoxide.
