Abstract
One embodiment of the present invention relates to a process for treating a flue gas stream () from a coal-fired boiler to reduce the amount of mercury contained therein. The process includes subjecting the flue gas stream () to a first wet scrubbing process for reducing the concentration of sulfur oxides therein and thereby producing a water-saturated flue gas stream () and subjecting the water-saturated flue gas stream to a second wet scrubbing process having an aqueous acidic solution comprising hydrogen peroxide to produce a flue gas having a reduced mercury content.
