Simulation of the atmospheric dispersion of gaseous effluents emitted by acement kiln

This work was conducted in order to study the atmospheric dispersion of gas eous effluents emitted by a cement kiln that uses coal as its source of fue l. The pollutants. analyzed were gaseous compounds (carbon monoxide, sulfur dioxide, and nitrogen oxides) and particulate matter. The simulation of at mospheric dispersion was made possible through the ISC-ST2 software develop ed by the US Environmental Protection Agency. The required experimental dat a were: the attributes of the stacks (the number of stacks, their location, height and internal diameter), meteorological data, volumetric flow rate a nd temperature of gaseous effluents, as well as the concentration of gaseou s compounds and particulate matter, the location and elevation of the recep tors and the location of the buildings within the industrial complex. The 2 4-h and annual concentrations of each pollutant were evaluated and these va lues were compared to current environmental standards. A study was also com pleted regarding the sensitivity of the parameters of the atmospheric dispe rsion model.
