| Abstract Scope |
Polycyclic aromatic hydrocarbons (PAHs) are naturally present in raw materials used to produced prebaked anodes for electrolysis of aluminum. Green anodes are baked to about 1200 °C over two – three weeks where organic hydrocarbon volatiles contribute to the carbonization process. Off-gases contain volatile and semi-volatile organic components, which are further treated to reduce environmental emissions by techniques such as regenerative thermal oxidizers and dry or wet scrubbers. Still, prebaked anode production contributes to a noticeable part of the reported PAH emissions in Norway. Samples of condensed matter have been collected from an off-gas treatment facility and the aromatic content have been characterized by various methods to investigate the presence of different categories of aromatic hydrocarbons and their properties to increase understanding of the processes occurring in the treatment facility. |
