Abstract
The present invention provides a method for the oxidation of Hgin coal fired flue gas to form Hgwhich is absorbed by the scrubber solution in wet-FGD or SDA, or adsorbed by the fly ash and subsequently removed from the flue stack with ESP and FF, and/or any other means as are known in the art for SO, NOand particulate removals. The addition of a second flue gas stream having a halogen and fly ash therein simultaneously with said hydrogen halogen or interhalogens into a coal fired flue gas further increases the oxidation of Hgto Hg.
