The Clean Air Act Amendments of 1990 listed 189 substances as hazardous air pollutants, of which 37 substances have been detected in power plant emissions. Of the 37 hazardous air pollutants, 11 are trace metal species. Mercury is trace metal species of greatest concern because of perceived risks from its environmental release and because it is present mainly in the vapor form and is not captured effectively by existing particulate removal systems. Carbon-based processes (both direct injection and fixed-bed) have been developed for control of mercury emission from municipal- and hazardous-waste incinerators. Existing data from the incinerators provide some insight on mercury control, but these data cannot be used directly for coal-fired utilities because mercury concentration, species, and process conditions differ greatly. This paper describes the results of phase I of a program to develop a sorbent for the removal of mercury from flue gas.
