research and development efforts to optimize mercury capture in wet flue gas desulfurization (FGD) systems and characterize the fate of mercury in the resultant by-products. Coal characteristics, combustion conditions, and air pollution control devices upstream of a power plant FGD system have an impact on the types and concentration of flue gas mercury at(More)
Based on results of field testing conducted by the U.S. Department of Energy's National Energy Technology Laboratory (DOE/NETL), this article provides preliminary costs for mercury control via conventional activated carbon injection (ACI), brominated ACI, and conventional ACI coupled with the application of a sorbent enhancement additive (SEA) to coal prior(More)
INTRODUCTION Coal-fired power plants utilize significant quantities of both coal and water for generating electrical energy. For example, a 500 MW power plant burns approximately 250 tons per hour of coal while using over 12 million gallons per hour of water for cooling and other process requirements a. The United States Geological Survey (USGS) estimates(More)
Simulations were carried out to analyze a promising new antimicrobial treatment strategy for targeting antibiotic-resistant bacteria called the \beta-lactamase-dependent prodrug delivery system. In this system, the antibacterial drugs are delivered as inactive precursors that only become activated after contact with an enzyme characteristic of many species(More)
: The four-area project was undertaken to further assess the impact of badger removal on the control of tuberculosis in cattle herds in Ireland. It was conducted between 1997 and 2002 in matched removal and reference areas in four counties, namely Cork, Donegal, Kilkenny and Monaghan, representing a wide range of Irish farming environments. In the removal(More)
(DOE/NETL) is conducting a comprehensive research, development, and demonstration (RD&D) program directed at advancing the performance and economics of mercury control technologies for coal-fired power plants. The program also includes evaluating the fate of mercury in coal by-products and studying the transport and transformation of mercury in power plant(More)
The U.S. Environmental Protection Agency (EPA) performed an Information Collection Request (ICR) in 1999 to gather additional information on the control and emission of mercury from coal-fired power plants. The ICR data indicates that a significant, but highly variable, amount of mercury removal can occur across a power plant's conventional air pollution(More)
