Abstract A technique for reducing and removing mercury in industrial gases, such as a flue gas, produced by the combustion of fossil fuels, such as coal, adds hydrogen sulfide and/or sulfide ions from a supply system to the flue gas as it passes through a scrubber. The scrubber may be either a wet or dry scrubber for flue gas desulfurization systems.
