| In the United States approximately 30% of total anthropogenic mercury emissions come from coal burning utilities. Under the Clean Air Mercury Rule, mercury emissions from utilities will be reduced through a market-based cap and trade system. Sorbent addition can enhance the removal of mercury from the flue gas, and inorganic sorbents are compatible with fly ash reuse applications. A titanium dioxide sorbent has been developed to capture mercury in coal combustor exhausts and increase the amount of mercury recovered in fly ash. The determination of the fate of mercury in combustion processes with sorbent addition has important implications for the management of fly ash disposal and reuse. The partitioning of mercury between the gas and particulate phases and the speciation of mercury in both phases was evaluated in laboratory and pilot-scale experiments. A sequential extraction process was developed and used to investigate the speciation of mercury in fly ash. |
