| The most promising mercury control technology for coal-fired power plants employs activated carbon to adsorb mercury; however, after implementation the high-carbon content of the collected fly ash makes it unusable for concrete applications. In response to this, Ceramatec has successfully demonstrated that by chemically treating the contaminated fly ash, it can still be used as a potential cement/binder for concrete applications. This treatement process physically encapsulates the mercury and activated carbon within the material matrix. Consequently, the treated fly ash does not interfere with the functionality of added air entraining agents in the ocncrete mix. Therefore, our treatment process allows coal-fired power plants to continue to sell their fly ash to ready-mix concrete manufacturers despite the addition of the activated carbon as a Hg-control technology. |
