The sintering operation in integrated steelworks is one of the main sources for the production of polychlorinated dibenzo-p-dioxins, polychlorinated-dibenzo-furans, NO x and SO x . 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.

“…A key issue arises when decision support embeds tools for process optimisation: although flowsheeting modelling is well-suited [22,23], most of these approaches make use of a separate software system that links different plant models and runs several optimisation steps within the simulation framework itself. Moreover, often the built-in optimisers in the process modelling environment allow only single-objective optimisation, whereas several objective functions need to be combined in an optimal operation of process industries.…”

Sintering is a process for ironmaking operations; it represents one of the main sources of production emissions of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzo-furans, NO x and SO x . In the present study, the operating conditions through which a reduction of dangerous emissions can be achieved are defined through numerical analysis. By employing a multiobjective optimisation tool, a deep analysis capable of representing the process behaviour leading to the optimal operating conditions was developed. Through such analysis, a broad range of processing parameters affecting the development of PCDD/Fs in the sintering process has been evaluated. The first aim was the possible reduction of dangerous emissions through numerical and experimental analyses allowing the definition of the optimal conditions for the minimisation of pollutants. Although the resultant optimal combination of input parameters able to reduce the dangerous emissions from the plant was determined, it was largely examined on the impact of the chosen input parameters on the sinter productivity. In such a way, it was possible to reduce the emissions close to the legal limits and with a high level of productivity and efficiency of the plant.
