Analysis of Air Pollutant Emission and Control System in Cement Industries around Ariyalur District

This research work presents data of the ambient air quality status of Ariyalur district of Tamilnadu, India. The air quality was assessed based on new national ambient air quality standard. The selected parameters were PM2.5, PM10, SO2, NO2. The average value of PM10 was found beyond the permissible limit at near power plant and near coal mill. The outcome of the study has been presented in the form of air quality index. AQI was found moderate for PM10 and PM2.5, SO2 & NO2, were observed in good range. Excess of PM10 is control in water spray system, road cleaning vehicles, choosing cleaner fuel system and consider alternative fuels such as gas instead of coal by reduced the coal. Adopted the electrostatic precipitator in coal mill. Modern ESP are designed to have high collection efficiencies of all types of fly ash, some are marketed as applicable to worldwide coal firing, collection efficiencies are now up to 99.81 %.
