Summary: | ISC-AERMOD dispersion model was used to predict air dispersion plumes
from an diesel power plant complex. Emissions of NO2 and SO2 from
stacks (5 numbers) and a waste oil incinerator were studied to evaluate
the pollutant dispersion patterns and the risk of nearby population.
Emission source strengths from the individual point sources were also
evaluated to determine the sources of significant attribution. Results
demonstrated the dispersions of pollutants were influenced by the
dominant easterly wind direction with the cumulative maximum ground
level concentrations of 589.86 μg/m3 (1 h TWA NO2) and 479.26
μg/m3 (1 h TWA SO2). Model performance evaluation by comparing the
predicted concentrations with observed values at ten locations for the
individual air pollutants using rigorous statistical procedures were
found to be in good agreement. Among all the emission sources within
the facility complex, SESB-Power (diesel power plant) had been singled
out as a significant source of emission that contributed > 85% of
the total pollutants emitted. |
