Conversion of elemental mercury to the oxidized form in a fabric filter baghouse
- Advanced Technology Systems, Inc., Monroeville, PA (United States)
The US Department of Energy`s Federal Energy Technology Center (DOE-FETC) has in the last several years funded efforts on identifying a sampling and analytical method to differentiate and quantify the chemical forms of mercury emitted from coal-fired electric utility boilers. DOE-FETC requested Advanced Technology Systems, Inc. (ATS) to develop new methodologies for determining the chemical species of mercury in coal flue gas, either by the modification of existing ones or by the introduction of novel methods. Through the efforts of ATS and others, this goal was attained and demonstrated by the final validation of the Ontario-Hydro Method. Also, in these mercury method comparison studies performed by ATS, conversion of elemental mercury to oxidized mercury in a fabric filter baghouse was observed. Investigation of this type of phenomenon was a step beyond mercury species measurement in that this had an impact on the design of mercury control devices for coal-fired power plants which must be mercury species-specific. Moreover, long and short term transport and deposition into the ecosystem with the resulting human and animal toxicity are the ultimate concerns and are all dependent upon the mercury species involved. Results will be reported from a five day study in which mercury species were measured and identified utilizing the Ontario-Hydro Method at the outlet of a baghouse accepting natural gas flue gas spiked with various mercury species.
