Predicting ambient concentrations of NO2 in a gas refinery located in South Pars Gas Complex
Jafarigol, F.; Atabi, F.; Moattar, F. & Nouri, J.
Abstract
In this study, AERMOD dispersion model has
been applied for predicting the values of ambient concentrations
of NO2 emissions due to the stacks of fourth gas
refinery located in South Pars Gas Complex in Asaluyeh,
Iran. First, the values of NO2 emissions from the stacks and
the amounts of ambient concentrations of NO2 in nine
monitoring stations have been measured in four seasons in
2013. Then, dispersion of NO2 emissions has been predicted
by using AERMOD model in the region with the
domain area of 10 9 10 km2, in average times of 1 h.
Finally, the simulated and observed values of ambient NO2
concentrations in the nine receptors have been compared.
Comparison of 1-h concentrations of the observed and
predicted results with the international ambient standard
levels shows that NO2 concentrations are higher than the
standard value. The results show that AERMOD model can
be used effectively for predicting the amounts of pollutants’
concentrations in the study area.
