Modeling of Sulfur Dioxide Gas Dispersion in Steel Industry

One of the problems raised in the steel industry is various pollutants produced by chemical interactions during steel production. Toxic emission modeling used to analyze the effect of pollutants on the environment. In this study mathematical modeling of air pollutants and carbon dioxide emission modeling was performed using software. Mass emission, specifications of exhausted smoke and chimney, meteorological data of topographic situation have been used as the main input of software. According to results the pollutants disperse more as the atmospheric stability decreases; as the wind speed is low the emission zone increases in different months of the year and in the same climate conditions due to lower mixing. Also the results showed that temperature and humidity has less effect than wind in pollutant dispersion. The highest pollutants were related to November and the lowest pollutants were related to December, January and June respectively.
