Impact of Cement Factories Stacks Diameter and Distribution on the Dispertion of Released Pullutants
The great development witnessed by the world right now accompanied by a large industrial progress to keep pace with the requirements of civilization. This leads to a large consumption of raw materials to be manufactured as materials necessary for the life of contemporary abstraction and oil refining and production of electric power and cement plants and food plants. Pollutants released from cement industry are various, such as sulphur oxides (SOx), nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2), particulate matter (PM) and others. Therefore, all organizations of environmental impact assessment (EIA) tries to predict the risk on the environment and human life before implementation this industry. This paper is to introducing and building model using AERMOD package to study the effect of stack diameter considering maximum hourly Prediction of SO2 NO2 and PM10 concentrations at different receptor points emitted from preconstruction plants with different numbers of stacks depending on the fixed stacks height 120m and exist velocity 20m/sec. the study was carried out for 14 * 14 km area. Based on the optimum diameter, the effect of stacks distributions on pollution dispersion was studied. The study showed that the diameter 3.5m is the optimum, and non significantly effect for stacks distribution. The research results are irrespective of background emissions reading caused by other industries and human activities.
