The paper presents two aspects concerned with the mercury air emission inventory from coal-fired public power and energy plants: an uncertainty analysis, using Monte Carlo simulation (Journal of the American Statistical Association, 44(247), 335-341 1949) and the monthly distributions applying the Denton-Cholette approach (Dagum & Cholette 2006). The analysis determines uncertainty about the estimates mercury air emission from 1990 to 2012 including the development of air pollution control (APC) technologies in the Polish public power and energy sector, also the monthly distributions in comparison with previously obtained results (Hławiczka 2008). The uncertainty of mercury (Hg) content in fuel is 31.6% for hard coal and 42.4% for brown coal. The confidence interval for the estimated emission changed from [kg] (16, 082.2; 16, 242.2) in 1990 to (10, 525.9; 10, 671.1) in 2012. However, the Denton-Cholette approach overestimates the emissions for the warmer periods of the year, but it could, however, in our view, be applied to attain the monthly distributions.

Sulfur, lead, and mercury characteristics in South Africa coals and emissions from the coal-fired power plants

et al. 2022

View full text Add to dashboard Cite

Coal-fired power plants (CFPPs) are the dominant source of electricity in South Africa due to natural abundance of coal in the country. However, emission of SO2, Pb, and Hg has raised serious environmental and public health concerns. Hence, to reduce emissions and utilize coal efficiently, estimating emission trend, understanding the forms of elemental occurrence in coals, and affinities to minerals, organic matter, and pyrite, are essential. Therefore, this paper aimed to assess the forms of elemental occurrence of sulfur, and Pb and Hg affinities to ash and sulfur, in the coals via statistical correlation and their isotopic compositions. This study also estimated SO2, Pb, and Hg emissions from 1971 to 2018 from the CFPPs on levels of activity and emission factors. Based on the results, South Africa coals mostly comprise equivalent fractions of organic and pyritic sulfur. The Pb were correlated with ash (R 2 = 0.393), which is an indication of the presence of bound clay mineral. However, the highest Pb 208 /Pb 206 and the lowest Pb 208 /Pb 206 in South Africa coals which contain high inertinite (organic matter) and low sulfur, reveal organically associated Pb.Similarly, clay minerals associated Hg appeared based on its relationship with ash (R 2 = 0.450), and the remaining could be an organic matter related. As an organic matter associated element least cleanability and readily oxidizing nature, burning South Africa coals containing a substantial quantity of organic sulfur and organically bound Pb and Hg without washing will obviously result to higher emissions. The estimated for SO2,
