NO2NOx

NO2NOx is a scientific term referring to the measurement and control of nitrogen oxides in industrial emissions. Nitrogen oxides, collectively known as NOx, are a group of gases that include nitric oxide (NO) and nitrogen dioxide (NO2). These compounds are formed during high-temperature combustion processes, such as those found in power plants, industrial boilers, and vehicle engines. NOx emissions contribute to air pollution, leading to the formation of smog, acid rain, and respiratory problems.

The term NO2NOx specifically highlights the importance of measuring both NO and NO2 in exhaust streams. While both are nitrogen oxides, their chemical behavior and environmental impacts can differ. Accurate measurement is crucial for effective emission control strategies. Various technologies are employed to reduce NOx emissions, including selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR). These processes involve injecting a reducing agent, such as ammonia or urea, into the flue gas to convert NOx into harmless nitrogen gas and water.

Monitoring NO2NOx levels helps industries comply with environmental regulations and assess the performance of their pollution control equipment. Continuous emission monitoring systems (CEMS) are commonly used to track these emissions in real-time. The ultimate goal of NO2NOx management is to minimize the release of harmful nitrogen oxides into the atmosphere, thereby improving air quality and protecting public health and the environment.
