Methods of treating mercury contaminated gas comprising: introducing a hydrogen halide selected from HBr and HI into a mercury contaminated gas stream containing a quantity of particulate matter at an introduction rate sufficient to create a concentration of at least 0.1 ppmvd; wherein greater than 50% of all particulate matter in the mercury contaminated gas stream is a native particulate matter; contacting a quantity of active bromine with the native particulate matter; creating a doped particulate matter; coating a filtration media with the doped particulate matter; and passing a portion of the mercury contaminated gas stream through the doped particulate matter on the filtration media and other related methods are disclosed herein.

Devices and methods for reacting carbon dioxide with ammonia to produce an ammonium bicarbonate containing product are disclosed. Further disclosed are methods and devices pertaining to the handling of ammonia, ammonium bicarbonate products, and waste products associated with that production.

Beneficial use of carbon

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.
