عنوان انگلیسی Air Emission Factors and Emission Rates in Asphalt Roofing Manufacturing
چکیده انگلیسی مقاله This study was focused on measuring air pollutants emission from factories producing the asphalt related products in Delijan Industrial Estate, which is the main center of asphalt related products in Iran. Emissions of four factories were analyzed for air pollutants using a stack analyzer, Testo 360, Testo Co., and Germany. The average concentration of all measured stacks for PM, THC, CO, NOx, SO2, and CO2 was 698.0, 195.4, 109.3,and 30.7, 15.1 mg/m3 and 5.17%, respectively. Estimation of the emission rate for the studied factories with total annual production of 46,500 tons of shingles and rolling asphalt revealed the annual emissions of 32.9, 8.9,5.0, 1.4, 1.1, and 4,423.4 tons/yr for PM, THC, CO, NOx, SO2, and CO2 respectively. It was also shown 435.4,118.2, 66.7, 189.4, 14.1, and 58,503.1 tons/yr for those pollutants by all factories in Delijan Industrial Estate with annual production of 615,000 tons. The emission factors for the above-mentioned pollutants were 708.1,192.2, 108.4, 30.8, 22.9, and 95,127 g/ton respectively. Comparing the results with national standard showed that, the PM emission concentration was 2 times greater than Iranian emission standard (250 mg/m3) and its emission factor exceeded the USEPA emission factor. The rest of pollutants concentrations and emission factors were in the range of both standards. In conclusion, all studied factories need to reduce their particle emission using appropriate air cleaners.
