A general analysis of chemical equilibria in a system consisting of the gaseous nitrogen monoxide, nitrogen dioxide, carbon dioxide, oxygen and of the solid sodium carbonate is carried out with respect to the equilibrium partial pressures of nitrogen oxides. The pertaining equations are derived for three regions of existence of the above system. The results are represented graphically and discussed from the point of view of removing the nitrogen oxides from the waste gases.
