Emission Estimation of Air Pollutants and Its Control Techniques at Cement Manufacturing Factory in Chandrapur District of Maharashtra State.

Abstract

Cement industry is one of the most causative anthropogenic sources involved in air pollution and the typical gaseous emission to air from it include nitrogen oxides (NOx), sulfur dioxide (SO2), carbon oxides (CO and CO2), particulate matter and some trace quantities of volatile organic compounds. This study has determined the sources of air pollutants with availing field survey at a cement manufacturing factory (CMF) in Chandrapur city. ‘Emission factor’ method from Emission Estimation Techniques (EETs) manual for cement manufacturing accredited by EPA, Australia has been adopted to estimate the annual emission of air pollutants by weight. At CMF the emission of air pollutants has been found approximately 385.767 metric ton/year which indicates 0.297 kg per ton of cement production. It has been observed that the emission of air pollutants from sampled CMF is comparatively lower than other CMF as the clinker and other additives are being imported here. But to ensure a complete healthy environment at CMF the necessary strategies have been suggested in this study for reducing the gap between standard level and current situation and to enhance the improvement of air quality management at CMF.
