What is the best way to construct a complete chemical-feed system for use in a power plant—piecing together equipment acquired from a hodgepodge of suppliers or creating a system with components sourced from
A new system to remove dissolved (ionic) mercury, along with other contaminants, from power plant wastewater is being developed. It is free of the drawbacks of using a traditional stannous chloride reagent
Many combined cycle power plants have established a pH guideline between 9.6 and 10.0 to minimize corrosion in heat recovery steam generators and condensers. Neutralizing amines are used to achieve these pH
In a move widely applauded by the power industry, the Environmental Protection Agency (EPA) and Department of the Army proposed a new definition of “waters of the U.S.” (WOTUS) that could exempt groundwater and ditches from regulation under the Clean Water Act (CWA). The measures follow other recent significant regulatory actions by the agency. On […]
