Air pollution may be defined as the presence of contaminations in the air by any physical, chemical, or biological agent that modifies the natural characteristic of the atmosphere.
Thermal oxidizer helps in destroying hazardous and toxic air pollutants as well as volatile organic compounds at a high temperature and releases them into the atmosphere. It destructs all major impurities which are present in the environment with the help of high temperatures and mediates the air pollution in chemical plants.
Therefore, the processing unit which is used for controlling air pollution in chemical plants is a Thermal oxidizer.
