Performance of Non-Halogenated Activated Carbon for Mercury Compliance

摘要

With the introduction of the first national standards for mercury pollution from power plants in December of 2011, many facilities will turn to activated carbon injection to meet the EPA Mercury and Air Toxics Standards (MATS) requirements. Activated carbon injection is a mature technology that is widely available and proven for achieving mercury removal greater than 90%. In anticipation of the need, Carbonxt has developed powdered activated carbons for mercury removal from coal-fired power plant flue gas. The products stand apart from most available mercury control sorbents in that they are non-halogenated. The Carbonxt products have been tested extensively at the Mercury Research Center under various conditions. The testing includes a span of injection location/particulate control configurations, injection rates, and concentrations of SO_3 (inherent and injected for flue-gas conditioning). This presentation reviews the mercury control performance and operational impacts of these recent test events.
