Abstract
A method of removing mercury from flue gas containing mercury and particulate solids emanating from a fossil-fuel energy conversion plant and passing through a flue gas duct. The method includes (a) contacting the mercury in the flue gas with a solution containing at least one chloride-containing salt dissolved in a solvent by injecting the solution into the flue gas duct at an injection location, in order to oxidize mercury into HgCl, (b) heating the solution prior to or after step (a) to at least about 300° C., and (c) removing oxidized mercury from the flue gas with a device for removing particulate solids from the flue gas.
