Abstract:

   Errors during the inventory of pollutant emissions occur due to failure to fulfill the requirement that the concentration of pollutants and the volume flow rate should be reduced to normal conditions. The effect of  water vapor content in the gas-air mixture on  result of the calculation of  emission efficiency is taken into account in very rare cases. The emission efficiency calculated without regard to humidity and temperature of the gas-air mixture can be significantly overestimated. Also  correctly established geometric parameters of sources of pollutant emissions have incontestable effect, their incorrect values can lead to considerable mistakes during estimation of pollutant emissions. Incorrectly calculated parameters of pollutant emissions can lead to incorrect estimation of ground level concentrations and determination of maximum permissible emission standards, which in turn can lead to unjustified costs for plants to carry out atmosphere-protective activities.

Keywords: emission efficiency, humidity of gas-air mixture, geometric parameters of pollution sources.
