Apart from being the principal contributors to acid rain, sulphuric and nitric acids undergo atmospheric transformation leading -or contributing- to the formation of PM10 in urban areas. It is relatively easy to remove SO2 from flue gases by absorption in water and reacting with alkali.
Air (N2+O2) is the source of NO at temperatures even at 1700 C and for a few milliseconds as in internal combustion engines -main polluters- where peak temperatures are in the range of 2200 C. Large coal fired heaters with preheating can reach peak temperatures of 1900 C with combustion times from 2 to 4 seconds !
NO is the principal nitrogen oxide present in flues. NO has a very low solubility in water. Unlike sulphur oxides that quickly react with water to form acids, NO must first be oxidized to NO2. So, wet limestone scrubbers are not efficient in the removal of NO.
NO and NO2 also play a significant role in the formation of unwanted ozone in the atmosphere.
