Mercury Removal-Ash Beneficiation (Patent Pending) The emission of mercury compounds from all sources, including coal-fired power plants, has drawn national and international attention due to the fact that certain forms of mercury have deleterious effects on wildlife and can be toxic to humans. Activated carbon injection (ACI) is by far the most effective and widely accepted technology to remove mercury from the flue gas of power plants. However, the implementation of ACI ahead of the primary electrostatic precipitator (ESP) or baghouse will inevitably increase the mercury concentration and carbon content in coal ash and is expected to affect the value of the ash. We Energies conducted a study to develop and demonstrate a technology to liberate and recapture the mercury adsorbed onto activated carbon and fly ash, and provide high quality fly ash for reuse in concrete applications or recycle sorbent used in mercury removal (62). A bench scale study was done to select an optimum combination of temperature and retention time to maximize mercury (Hg) recovery. Fly ash samples taken from Presque Isle Power Plant (PIPP) were used in the experiments. The total Hg concentration in the sample was determined by cold-vapor generation atomic fluorescence spectroscopy (AFS). Samples were treated in a muffle furnace in an inert atmosphere at different temperatures ranging from 371ºC to 538ºC for retention times of one to five minutes. A nitrogen atmosphere was maintained to keep the carbon from igniting. The percent of Hg liberated from the ash samples was determined by measuring the total Hg left in the ash after thermal treatment. PIPP fly ash Units 5 & 6 was derived from western bituminous coal and colleted using a precipitator. The original total Hg concentration in the sample was 0.42 ppm. The results indicated that both temperature and retention time are important parameters in the thermal desorption process. At temperatures lower than 482ºC, the maximum Hg removal was 40% even with prolonged thermal treatment. More Hg can be removed with higher temperature and longer treatment. At 538ºC, 90% of the Hg was liberated from the fly ash within four minutes. Figure 9-6 shows the rate of Hg removal from PIPP fly ash in the muffle furnace using different combinations of temperature and retention time. Based upon the test results obtained from the bench scale study, a test program was designed to generate experimental data from a pilot apparatus The pilot test apparatus is comprised of seven main components: a coneshaped hopper, air slide, baghouse, burner, collector underneath the air slide, Hg condenser, and wet scrubber. During each fly ash processing run, samples were fed into the air slide through the cone-shaped hopper. The speed of sample going through the system was controlled by a rotary feeder.
