Studies were carried out on the iron sintering process to investigate: the effects of sinter mix composition on the emissions of toxic organic compounds such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs), heavy metals and oxides of nitrogen (NOx.); conditions whereby revert materials can continue to be recycled through the sinter plant; and, the use of sinter mix additives and selective catalytic reduction with ammonia for the minimisation of NOx emissions. The work was carried out by a coordinated programme of work involving Corus UK Limited, BFI, Aceralia and CENIM. Corus UK Ltd and BFI studied the influence of sinter mix composition on emissions of PAHs, PCBs and PCDD/Fs by means of sinter pot experiments and measurements on production scale sinter plants. Aceralia and CENIM investigated the influence of revert materials on the formation of NOx and the emissions of heavy metals and alkali chlorides. Aceralia, CENIM, INCAR and the Instituto de Catalasis y Petroleoquimica (ICP) examined methods for the minimisation of NOx emissions by the use of sinter mix additives and selective catalytic reduction. Overall the work highlighted the important role of alkali chlorides in the formation of organochlorine compounds and emissions of fine particulates and heavy metals in the sintering process. A novel catalyst was developed for the selective catalytic reduction of NOx at temperatures down to 210°C, but the use of sinter mix additives did not significantly reduce the formation of NOx.
