MODELING ATMOSPHERIC EMISSIONS DURING OLIVE HUSK DRYING AND STUDY OF METEOROLOGICAL FACTORS EFFECT IN THE VICINITY OF URBAN AREAS

Abstract

In this work, we present field measurement data and modeling of air pollutant during one season at an urban area in Sousse, east Tunisia. We analyzed the average pollutant emission and we used our data to evaluate a dispersion model. The impact of various meteorological factors on pollutants concentrations has been studied. The model predicts that the concentrations of CO and CO2 in an urban area can reach 50 mg.m-3 and 185 mg.m-3 respectively. The height of the chimney, the wind velocity, the fuel nature, the air excess and the combustion temperature have an influence on the concentrations of pollutants and their dispersion.
