Technology Could Deliver 90% Hg Reduction from Coal: Reducing mercury emissions at coal-fired power plants by 90% has been considered the holy grail of mercury control. A new technique promises to get us there-at a price

摘要

For at least a decade, the electric utility industry has argued that reducing airborne mercury emissions from coal-fired power plants to the 90% level that environmentalists and many regulators have advocated is technically impossible. That may be about to change, according to presentations in the "Hg Technologies" sessions at the ELECTRIC POWER conference in Chicago this May. Much greater mercury capture than the 30% to 50% now available may be on the horizon for both eastern bituminous and Powder River Basin coal.
