ABSTRACT:
Industrialization is highly desirable for the sustenance of a nation’s economy and the enhancement of the citizenry’s well being. However the negative impact precipitated by introduction of its unwanted by – products into ecological system may be catastrophic if allowed to build up and uncontrolled. Urban Air pollution due to activities of process industries is one of the main problems faced by the industrial area of the world. Experimental analysis was carried out on gas flare to determine the extent of air pollution by the petroleum refinery industry on the concentrations of NO, CO, SO2 and total hydrocarbon. Attempt at the modeling pollutant concentration from the flare point using visual basic is hereby presented. The model equation was used to simulate the concentration of pollutants at distance of 20, 40, 60, and 80, 100, to 1000 away from the flare point. The result of the simulation of model developed from the modified principle of gaseous dispersion by Gaussian showed a good agreement with the experimental results with average correction coefficient of 0.99. Results obtained reveled that the concentration of pollutants are unacceptable compare to the Federal Environmental protection Agency set limit. The dispersion pattern of pollutants showed that the extent of spreading is dependent on nearness to the source of flare, wind speed, temperature etc.
