Estimating gaseous pollutants in the air near Daura Refinery, Daura Power Plant and South of Baghdad Power Plant by calculating the fuel discharge

Abstract

This study addresses estimation of emission rates and concentrations of SO2, CO and NO2 gases emitted from Daura Refinery (DR), Daura Power Plant (DPP) and South of Baghdad Power Plant (SBPP) by calculating the fuel discharge. The estimations were made by using the Gaussian plume model of dispersion at distances within 10 km from the pollution source for January, April, July and October 2017 under two stability conditions, slightly stable and moderately unstable. The effect of wind speed and direction as well as the ambient temperature of the surrounding air on the dispersion and transmission of air pollutants were also investigated. It was found that the unstable conditions are better for dispersing out atmospheric pollutants. The results showed that Zafarania District was the most affected by pollutants emitted from DR and BSPP while Daura District was more affected by DPP due to the prevailing wind direction. It was also found that an increase in wind speed leads to a decrease in the concentration of pollutants. The concentration of pollutants is inversely proportional to the height of the chimney, the speed of the gas leaving the chimney, while it is directly proportional to the diameter of the chimney. DPP has higher emission rates than DR and SBPP while at the surface level, the pollutants concentrations emitted from DR are greater than those emitted from DPP and SBPP.

“…However, research on transportation habits suggests that this trend towards suburbanisation has led to an unexpected increase in car ownership, a decrease in public transportation usage, longer commute times, and greater distances travelled. All these factors contribute to the rise in emissions, primarily of VOCs (volatile organic compounds), NO x , CO, PM (particulate matter), and minor components responsible for photochemical smog [1,2]. In highly developed countries belonging to the OECD (Organisation for Economic Cooperation and Development), motor vehicles are the primary cause of environmental pollution, releasing over 15,000 chemical compounds [3][4][5].…”
