摘要
The aim of present research is to study the dispersion of air pollutants using the air quality model, AERMOD and to predict the impact of pollutants (PM<sub>10</sub>, NO<sub>2</sub> and CO) at the receptor level released from Gas Based Power Plant (GBPP). The net-concentrations including monitored data plus predicted values of PM<sub>10</sub>, NO<sub>2</sub> and CO would be increased from base value 75 to 77.61 μg/m<sup>3</sup> with an increase of 3.48%, 22 to 26.66 μg/m<sup>3</sup> with an increase of 21.18% and 428 to 538.37 μg/m<sup>3</sup> with an increase of 25.79% respectively. The study of hill effect showed that it had profound impact upon the dispersion of pollutants and the ratio (with hill and without hill) of each pollutant was 3.89 for PM<sub>10</sub> (24 hr), 2.40 for NO<sub>2</sub> (24 hr) and 13.98 for CO (1 hr). The natural gas based plant not only decreases the pollution level but also reduces the hospital treatment cost and protects the public health. The modeling results suggest that the GBPP could be a clean technology as replacement of coal power plants located in the city which pollute the environment considerably in spite of control measures installed.
