Carbon Footprint for Mercury Capture from Coal-Fired Boiler Flue Gas

Power production from coal combustion is one of two major anthropogenic sources mercury emission to the atmosphere. The aim this study analysis carbon footprint removal technologies through sorbents injection related 1 kg flue gases. Two sorbents, i.e., powdered activated and coke dust, were analysed. assessment included both direct indirect emissions various energy material needs life cycle including mining transport, production, transport power plants, into results show that at average concentration in processed gasses accounting 28.0 µg Hg/Nm3, gases required 14.925 Mg 33.594 respectively. However, whole for amounted 89.548 CO2-e·kg?1 Hg, whereas dust value was around three times lower 24.452 Hg. Considering relatively low price its impact on GHG emissions, it can be found as a promising alternative commercial carbon.
