Calgon Launches Products to Control Mercury Emissions
The new line, which includes the Fluepac MC+ Ultra, Fluepac MC Maxx and Fluepac ST, can reduce carbon injection rates by 50 to 70 percent below that of standard products, while exceeding the mercury removal requirements recently established by the EPA’s Mercury and Air Toxics Standards, Calgon says.
By replacing the standard halogenated and non-halogenated products, the Fluepac products result in lower activated carbon injection rates, thereby lowering the overall treatment costs associated with achieving mercury emission objectives. Additional savings result from fewer carbon deliveries, less wear on systems and a decrease in the injection system size.
Fluepac ST – the most versatile and advanced of the products, according to Calgon – can reduce the negative impact of sulfur trioxide on standard carbon performance. The product can deliver 90 percent mercury capture in SO3 concentrations up to 15 parts per million at injection rates less than 10 pounds per million actual cubic feet of flue gas, Calgon says.
The EPA issued requirements to control mercury and other toxic air emissions from coal- and oil-fired power plants in December 2011.
