Abstract

The sintering operation in integrated steelworks is one of the main sources for the production of polychlorinated dibenzo-p-dioxins, polychlorinated- dibenzo-furans, NOx and SOx. In the present study, the operating conditions, through which a reduction in emissions can be achieved, were defined through numerical analysis. The following process parameters were evaluated: gas temperature, quantities of chlorine and copper and additions of hydrated lime, sulphur and urea. Using the optimisation software modeFRONTIER (ESTECO), a virtual surface that can reproduce the actual process of sintering was created. Additionally, with the application of filtering to postsintering gas, such as electrostatic precipitator and wetfine scrubber, it was possible to obtain a reduction in emission values within the limits of international protocol Aarhus.
