Fluepac - Model ST -Powdered Activated Carbon

• Large number of high energy adsorption pores
• Good transport pore structure
• Completely devolatilized bituminous coal-based material

• High adsorption capacity for many pollutants.
• Effluent mercury levels can be reduced by over 95%.
• Rapid adsorption kinetics lead to low required contact times.
• Product has a high ignition temperature which permits use over a wide temperature range.
• Safe bulk storage.

FLUEPAC-ST has been proven to be particularly effective in applications where there are elevated S03 levels in the flue gas (such as coal-fired boilers burning high sulfur coals). In the presence of S03, mercury is much more difficult to remove with standard activated carbons like FLUEPAC-MC Plus. The performance improvement that can be expected by using FLUEPAC-ST is illustrated in figures 1 and 2. The data used to generate these figures was taken from two different utilities in the eastern U.S. As shown, the FLUEPAC-ST product greatly reduces the amount of carbon needed to achieve efficiencies above 70%.

FLUEPAC-ST is injected directly into the flue gas stream and easily removed by existing particulate control devices. FLUEPAC-ST can be landfilled with the ash as a non-hazardous material.
