Greater understanding of the causes and nature of dispersion of atmospheric emissions from a modern integrated steelworks is essential if reduction in the effects of industrial pollution are to be made. Relationships have been established and quantified between process conditions and resultant atmospheric emissions from major steelworks emission sources. These relationships will allow emission rates to be predicted, potentially on a real time basis, based on the prevailing process conditions. Meteorological conditions are the most important factor affecting steelworks emissions dispersion. The interaction of prevailing wind with local terrain and surface roughness changes has the effect of changing the location of maximum ground level concentrations and their magnitude. The coupling of real time emissions data with real time meteorological data via an atmospheric dispersion model makes it possible to predict the contribution of crossboundary steelwork emissions to local air quality on an hourly basis. |
