Modélisation de La dispersion atmosphérique de quelques polluants

The development of industries in Morocco has led to the multiplication and diversification of air pollutants.The dispersion of the pollutants discharged by the weather favors. In this context, this work is devoted to modeling and simulation of the effects of these weather conditions, which are the temperature, the speed and the wind direction ,on the dispersion of pollutants from chimney sulfuric workshop of OCP Jorf-Lasfar ie SO2, SO3. Advanced numerical simulation tool was used with a method of analysis to study the effects of weather conditions on the atmospheric dispersion, followed by a critical study results that permits to deduce that the most disperse pollutants is SO2.
