Procedures of Optimisation of Postcombustion Reactions Leading to Abatement of Dioxin Emissions

High temperature incineration and similar thermal processes lead to the formation of « dioxins » in trace amounts. The optimisation of the (post-) combustion process might reduce the level of emissions not only of PCDD/Fs but also of other incomplete combustion products harmful for the environment. The objective is to destroy, by total oxidation, the dioxins and the byproducts resulting from their destruction if we want to avoid the reformation of dioxins by catalytic or de Novo reactions in the cooling section of the industrial units (heat exchangers, filters...). In this paper, we study the influence of the postcombustion parameters on dioxins abatement by a simulation approach using the detailed mechanism of dibenzofuran oxidation
