| About one-third of the fly ash generated from the combustion of coal in power plants is being used as an additive in concrete, which is the biggest market for fly ash. However, more and more power plants are being retrofitted with the activated carbon injection (ACI) system to comply with the new federal and state mercury regulation. When conventional carbon-based mercury sorbents are used, the ash can no longer be sold for its highest-value use, as a replacement for cement in concretes. A novel carbon-based mercury sorbent, C-PACTM, has been developed by Sorbent Technologies that allows fly ash to continue to be used in concrete applications. Following the first full-scale month-long test in Midwest Generation's Crawford station, C-PACTM was recently tested in another full-scale coal-fired power plant, Midwest Generation's Will County Station. Updated mercury removal and concrete test results from these two trials are presented in this paper. |
