Abstract

The industrial and technological development of the last century has led to increasing energy consumption, which has led to an increasing increase in the discharge of gaseous pollutants into the atmosphere. In these discharges, nitrogen oxides account for a large part of the environmental pollutants and are there fore directly or indirectly responsible for certain diseases when their concentration in the air is high. In this work, we propose to numerically simulate the evolution of the density of NO$_x$ nitrogen oxides present in the gas mixture N$_2$/O$_2$/H$_2$O/CO$_2$ which is subjected to different values of the reduced electric field: 100 to 200 Td (1Td = 10$^{-17}$ V.cm$^2$ ). We are particularly interested in the NO, NO$_2$ and NO$_3$ species that are the main components of nitrogen oxides. The simulation runs from 10$^{-9}$ to 10$^{-3}$ s. The model takes into account twenty species reacting with each other following two hundred chemical reactions. The results obtained clearly show the effectiveness of the reduced electric field in the destruction of nitrogen oxides.
