Removes Mercury

The mechanisms by which an activated carbon removes mercury from flue gas are complex. The large surface area and pore volume of enviraPAC Hgâ„¢ provides sites for mercury atoms to be held to the carbon, but the low concentration of mercury in the flue gas (5-20 micrograms per meter cubed), the short exposure time of the carbon, and the presence of compounds such as SO3 which compete with mercury for sorption require proprietary modifications to increase the force of attraction between the carbon and mercury. EnviraPAC Hgâ„¢ can be modified with proprietary impregnation, to best suit the needs of a particular coal burning installation. EnviraPAC HGâ„¢ selects feedstock based on physical structure and ash composition best suited for specific mercury capture and then utilizes proprietary methods of impregnation adding compounds which then selectively bind mercury over other competing molecules.
