The need for quicklime has led to increased utilization of used oil as a substitute for fuel in its combustion process. Mahaka Lime Factory produces SO2 and NOX, which are emitted through the chimney and proportional to lime burning. Therefore, it is necessary to monitor the distribution of the emission concentration in the ambient air. One of the methods used to facilitate the monitoring process to ensure it is kept below the quality standard is dispersion modeling. This is an analytical model processed with the help of AERMOD software and the Gaussian equation. The SO2 concentrations of 0.001 mg/m3 and 0.001 mg/m3, as well as NOX of 0.027 mg/m3 and 0.044 mg/m3 obtained from the calculation, were below the applicable quality standard. Furthermore, emission concentrations directly observed were more significant than the Gaussian modeling results due to the presence of other pollutants around the factory. In conclusion, the dispersion modeling using AERMOD software showed that the largest and lowest distribution of emission concentrations are in the cliff area around the emission source and on the ground surface close to the chimney. |
