Pollutants in Emissions to Air – What’s in the Smoke?
Speaking of industrial emissions to air, it is often a matter of emissions resulting from combustion processes. The main components of the emissions are nitrogen and some excess oxygen originating from the incoming air being fed to the combustion process, as well as water and carbon dioxide (CO2) being the primary results of the combustion reactions. The concentrations are at percentage levels. ...
