Pljevlja lignite carbon emission characteristics

ABSTRACT
The anthropogenic emission of greenhouse gases (GHG) especially carbon-dioxide has to be limited and reduced due to their impact on global warming and climate change. Combustion of fossil fuels in the energy sector has a dominant share in total GHG emissions. In order to reduce GHG emission, European Union (EU) established a scheme for GHG allowance trading within the community, and the implementation of the EU emission trading scheme (ETS), which is a key to GHG reduction in a cost-effective way. An important part of ETS is prescribed methodology for monitoring, reporting, and verification of the emission of GHG including characterization of the local fuels combusted by the energy sector. This paper presents lignite characteristics from open-pit mine Borovica-Pljevlja, which has highest coal production in Montenegro (>1.2Mt/year), including evaluation of its carbon emission factor (CEF) based on the laboratory analysis of 72 coal samples. Testing of the samples included proximate and ultimate analysis, as well as, net calorific value (NCV) determination. In accordance with the obtained results, linear correlations between NCV and combustible matter content, carbon content and combustible matter content, hydrogen content and combustible matter content, carbon content and NCV, were established. Finally, the nonlinear analytical correlation between CEF and NCV for Pljevlja lignite was proposed, as a base for the precise calculation of carbon dioxide emission evaluation.
