•     How is the best way to store , inject and distribute the carbon

•     Where should the carbon be injected

•     If both an alkaline reagent and AC are injected  where are both injected.

•     If a precipitator rather than baghouse is in place, how much more carbon will be needed?

•     Should I inject bromine with the coal and then use non impregnated AC

•     Will activated carbon recirculating  in a wet FGD allow mercury separation from gypsum and wastewater.
