Abstract:
1. A method of reducing an amount of mercury discharged to an environment in a flue gas generated by combustion of a fuel source, said method comprising: contacting said flue gas with a moist pulverous material upstream of a particle separator, wherein said moist pulverous material facilitates the removal of acid gases from said flue gas; mixing powdered activated carbon (PAC) in an amount between about 0.5 lb/MMacf and 10 lbs/MMacf with said flue gas upstream of said particle separator, wherein said PAC interacts with at least a portion of mercury containing compounds in said flue gas; and separating said mercury containing compounds from said flue gas containing said moist pulverous material and PAC, thereby reducing an amount of mercury in said flue gas.
