CO DISPERSION SIMULATION OF HIGH BURNERS FROM PROCESSED UNITS AT THE NATIONAL IRANIAN SOUTH OILFIELDS COMPANY BY SCREEN 3
Introduction: Dispersion of pollutants from burners and stacks has been always one of the most important environmental concerns in some industries such as oil due to the personnel exposure to pollutant sources. All combustible burners, release hazardous pollutants in environment. The target pollutant in this study is carbon monoxide derived from combustion, so the perpouse is finding the distance from burner which the risk for inhalation of this pollutant is high due to the highest concentration of this pollutant at this distance.
Materials and methods: In this study, 4 pollution sources at the National Iranian South Oilfields Company were selected, then the exhaust gases, temperature, wind velocity, and the other parameters were measured by measuring instruments in order to carry out by Screen 3 for dispersion of CO.
Results: The highest concentration of CO ( 27.04 μg / m3 ) at difference of 226 m from station 3 were determined in the stability class C. The exhaust gas velocity of burner was assumed as the most critical mode, 10 m / s, considering the exhaust gas temperature from burner was 1000 ° C.
Conclusions: Results showed that the burners of this unit are safe and in compliance with the standards in terms of CO emission.
