At the coking plant, there are many manufacturing processes which generate air pollutants and impact on the environment, including coke quenching. Inventory of emission of coke production process make significant contribution to air pollution control and environmental management. In this studying, concentrations of pollutants being CO, SO2, NOx in coke quenching process were determined. Samples of gaseous pollutants in the flue were collected using a stack sampler of APEC XC572-V and following USEPA methods 6, 7, 10. Based on monitoring and the process information, total emissions and emission factors of these pollutants for this process were determined. Based on burning fuel, the emission factors of CO, SO2, and NO2 in the experiment were 0.029 mg/kg; 0.012 mg/kg; and 0.004 mg/kg, respectively. Alternatively, based on coke product, the emission factors of CO, SO2, and N02 in the experiment were 0.035 mg/kg; 0.015 mg/kg; and 0.005 mg/kg, correspondingly. The results obtained from the research can be used for industrial emission inventories and air quality management in Viet Nam.
