Part 3 of Abating Hazardous Air Pollutants: NOx
What is NOx? The term NOx refers to the family of air polluting chemical compounds, Nitrogen Oxides. NOx represents seven different compounds although only one, Nitrogen Dioxide, is regulated by the EPA. Nitrogen Dioxide (NO2) is carefully monitored by the EPA as not only an air pollutant but also for its reaction with the ozone and the creation of acid rain. NO2 is reddish-brown gas with a bitter odor similar to that of Chlorine. NO2 is also commonly referred to as Nitrogen Oxide and Deutoxide of Nitrogen and is highly reactive.
NO2 is an intermediate in the manufacturing nitric acid. Nitric acid is a nitrating agent in the manufacturing of chemical explosives, as a flour bleaching agent, as an inhibitor for acrylates and an oxidizer in rocket fuel. It was used in the Titan rockets which launched Project Gemini, in numerous unmanned space probes and remains in use for space travel in the maneuvering thrusters of the Space Shuttle. [Read more…]
