Abstract

Sintering is a fundamental process for ironmaking operations, it represents one of the main sources of production of PCDD (polychlorinated dibenzo-p-dioxins), PCDF (polychlorinated -dibenzo-furans), NOx and SOx. In the present study the optimal operating conditions, through which a reduction of dangerous emissions can be achieved, are underlined through numerical analysis. By employing a multi-objective optimization tool, a deep analyses capable of representing the process behavior 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 analysis allowing the definition of the optimal conditions for the minimization of the pollutants. Although the resultant optimal combination of input parameters able to reduce the dangerous emissions from the plant, it was largely examined 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 with an high to with an high level of productivity and efficiency of the plant.
