Abstract
A system and method is provided for the removal of mercury from flue gas. Effective removal of mercury is obtained by oxidation of elemental mercury, with highly reactive halogen species derived from dissociation of halogen compounds at moderate temperatures brought into contact with the flue gas with or without the addition of carbon.
