Survey of pollutant emissions from stack of Saman cement factory of Kermanshah city from year 2011 to 2012

Toxic gases and hazardous particulates that release into environment from cement factories have considered as the environmental problems. This study aimed to determine the level of air pollutants from the stacks and the ambient air of the Kermanshah Saman cement factory and its comparison with existing standards. This is a Descriptive - analytical study. The assessed parameters include the suspended particles CO, NO2, NO and SO2 from pre-heater, crusher, and electro filter have performed according to the method of Perkinz air pollution control. Results showed that amount of suspended particulates was lower than the industry emissions standard, which has been approved as a national standard for crusher (200 mg per cubic meter) electro-filter (150 mg per cubic meter). However, the amount of gases emission was more than standard. This study revealed that the controlling devices have good ability in particles control. Although the exhaust gases seemingly different from the standard, but the difference is not significant.However further controls are recommended for control of gases pollutants.
