Emissions of polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs) and polycyclic aromatic hydrocarbons (PAHs) from a cement kiln using a continuous monitoring system

Resumen de la comunicación presentada en PIC2015 – the 14th International Congress on Combustion By-Products and Their Health Effects, Umeå, Sweden, 14-17 June 2015.

The aim of the present study was to assess the emission of di2erent persistent organic pollutants from a cement plant over a period of one year, under normal operating conditions. In this way, a Dioxin Monitoring System (a long-term sampling device manufactured by Monitoring Systems) was installed in the clinker kiln stack of the cement plant, located in the vicinity of the University of Alicante. The factory has a production capacity of 150 t/h of clinker and uses petroleum coke as primary fuel, but also alternative fuels such as SRF (solid recovered fuel), ASR (automotive shredder residue), sewage sludge, waste tires, and meat and bone meal wastes, with an enerKy substitution level of about 40 %. The study consisted of a total of 13 samples, namely: • Ten samples collected in 3Q4 week periods, for the determination of brominated dioxins and furans (PBDD/Fs). • Three samples collected during one-week periods, for the determination of polycyclic aromatic hydrocarbons (PAHs).
