Control of Mercury Emissions from Coal-fired Electric

boilers. This results in current emissions of 48 tons of mercury. 1. There are two broad approaches to mercury control: (1) activated carbon injection (ACI), and (2) multipollutant control, in which Hg capture is enhanced in existing/new SO2, NOx, and PM control devices. Relative to these two approaches, this paper describes currently available
