Modélisation de l’atténuation au sol de la concentration des émissions d’une centrale thermique diesel

Abstract

A ground level diesel power plant pollutants mitigation model

A three steps environmental mitigation model is investigated as a way of controlling the emission rates of a 44 MW diesel electric power plant located in downtown Ouagadougou. First of all, an environmental audit finds it necessary to rehabilitate the plant in order to improve its performances. To be effective however, the upper limit of the plant fuel consumption should not exceed 229 g/kWh. Finally, dispersion diagrams are obtained from a simplified dispersion-advection submodel, capable of predicting the plant stack high for which, the ground level pollutant concentrations must compley with the ambient air quality standards. Thus, the results of this model may be utilized to control and regulate air pollution.
