Removal of Hg0 in wet FGD by catalytic oxidation with air - A contribution to the development of a process chemical model

- Modification of FGD chemistry prevents reduction of Hg(II) and enables oxidation of Hg(0) thus retaining mercury in solution.
- Mercury in FGD can be oxidized by catalytic reactions with transition elements.
- Presence of ligands can stabilize oxidized mercury in FGD system.
- Chemical model developed can be used for the predictions of reactions.
