A conversion process for the removal of mercuric-based compounds from a primary flue gas stream:
- providing a source of flue gas containing mercury and mercuric-based compounds,
- providing a mercury absorbing media comprising a fabric containment layer, and a mercury absorbent,
- providing a source of NO2 into the flue gas stream upstream of the mercury absorbing media,
- passing the mercury containing flue gas through the mercury absorbing media, thereby producing mercuric oxide,
- processing the flue gas to remove the mercuric oxide and other components.
