The study was conducted on a lignite burning thermal power plant which combines five power units totalling 775 MW with a yearly consumption of about 4 million tons of lignite. A mass balance for mercury and 39 trace and major elements was estimated in two units under different operational conditions. Among other trace elements the distribution of volatile As, Br and Se were also followed, showing that Se and Br are enriched along with Hg in the FGD products.

The aim of the study was to evaluate the behavior of mercury in the cement clinker production process. It was shown that the process comprises many mercury cycles which are strongly dependent on the operating conditions and technological specifics. Cycling of mercury causes a significant enrichment of mercury inside the process. The quantities of Hg(t), Hg(g) and Hg2+(g) emitted were higher when operating with the raw mills off (direct mode). It was seen that the efficiency of Hg removal was strongly related to the dust removal efficiency.

A method using radiotracer 197-Hg of high specific activity was developed and validated. The method alows to study mercury oxidation and reduction in aqueous media, as well as partiotioning of Hg(II) between aqueous and solid particles. This is very usefull toll to study mercury behaviour in wet FGD in laboratory scale experiments.
