  • Mercury Control Demonstrations

    C1.1 | Halogens and Sulfur in Coals and their Influence on Co-benefit Mercury Capture Bernhard Vosteen | President, Vosteen Consulting Gmbh Not only the range of the coal mercury content itself, but also the range of the native halogen and sulfur contents in coal are of great influence on co-benefit mercury capture, wet and dry. The ...

  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

  • EVALUATION OF STRATEGIES FOR MERCURY MACT COMPLIANCE

    On December 15, 2003, the United States Environmental Protection Agency (U.S. EPA) proposed a rule with two alternatives to permanently reduce mercury (Hg) emissions from power plants. Under one alternative, which is the focus of this paper, the utilities would install controls known as Maximum Achievable Control Technologies (MACT) under section 112 of the Clean Air Act (CAA). The proposed rule ...

  • EPA mercury rules: Keeping the lights on while removing toxics from our air

    Next week the U.S. Environmental Protection Agency is expected to finalize new rules to reduce mercury and other toxic air emissions that will affect dozens of antiquated power plants currently operating without pollution controls. These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will new EPA ...

  • Mercury and other trace elements in Ohio River fish collected near coal‐fired power plants: Interspecific patterns and consideration of consumption risks

    Many coal‐fired electric generating facilities in the US are discharging higher loads of Hg, Se, and other chemicals to receiving streams due to the installation of flue gas desulfurization (FGD) air pollution control units. There are regulatory concerns about the potential increased uptake of these bioaccumulative trace elements into food webs. We evaluated the concentrations of As, THg, ...

  • Global solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Modest Growth for Air Pollution Control Market

    The Clean Air Act amendments of 1990 created a wave of optimism in the air pollution control (APC) business. The subsequent decade, however, resulted in backwash of disappointment for APC companies as the market for stationary source equipment declined from 1-4% per year from 1993-1998. Growth returned to the APC market, however, with 1999 and 2000 characterized as 'good' years by the Institute ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...
