A technique for reducing and removing mercury in industrial gases, such as a flue gas (16), produced by the combustion of fossil fuels, such as coal (24), adds hydrogen sulfide and/or sulfide ions from a supply system (50) to the flue gas (16) as it passes through a scrubber (30). The scrubber may b...

Beschreibung
Zusammenfassung:	A technique for reducing and removing mercury in industrial gases, such as a flue gas (16), produced by the combustion of fossil fuels, such as coal (24), adds hydrogen sulfide and/or sulfide ions from a supply system (50) to the flue gas (16) as it passes through a scrubber (30). The scrubber may be either a wet or dry scrubber for flue gas desulfurization systems.
