Abstract
In the last decades, the propagation of chemical compounds in the atmosphere, coming mainly from human activities, has attracted attention. Faced with this, there is a compilation of emission factors for industrial sources. This is called "AP-42" - Compilation of Emission Factors of Atmospheric Pollutants. This work has developed a computer program that estimates the emission rates of the main compounds of a thermoelectric plant from the combustion of coal and the second part of the program carries out the propagation, dispersion and chemical reactions in the atmosphere. In this work the simplified chemical mechanism using only the chemistry of the Nitrogen gases (NOx) is compared to a mechanism containing the chemistry of Nitrogen gases and the volatile organic compounds ("VOC"). Also shown is the solution method of the System of Coupled Ordinary Equations for the set of chemical reactions presented. The numerical results are presented for the concentrations of the gases Nitric Acid (HNO3), Nitrogen Dioxide (NO2), Nitric Oxide (NO) and Ozone (O3).
