The kinetics of the Formation and Propagation in the Atmosphere of the Secondary Gas Emissions of Metallurgical Enterprises

Abstract

There was considered spatial physicochemical model of secondary gas substances of gas emissions, which allows two parallel processes: the wind carrying of the primary substance and its transformation into a secondary substance. The proposed model allows us to predict the spread in the lower atmosphere layers of the secondary gas emissions of anthropogenic origin, in particular, secondary emissions of continuous running metallurgical complexes. There was presented the solution of spatial model of the source in an analytical of chemical kinetics method. As a result become available an analytical function of the distribution of secondary substances taking into account its formation, wind transport and “destruction” of secondary substances in the atmosphere. To confirm the adequacy of kinetic model there were compared calculation results obtained by numerical and analytical method for the same conditions of the task. Both proposed models give the same results, and which of them can be used to build the fields concentration of substances of secondary emissions in the outer zone of influence of large industrial enterprises.
