Mercury Research Laboratory

Mercury Research Laboratory
The Mercury Research Laboratory (MRL) specializes in bench-scale systems studying mercury, SOx/NOx, catalysts, sorbents, and related work. Two bench-scale systems capable of simulating flue gas conditions such as temperature, particulate loadings, air-to-cloth ratios, and various gas concentrations (e.g., SO2, O2, CO, CO2) are used.

Laboratory Facilities

Major equipment and instrumentation include the following:

  • Mobile sampling trailer for mercury field testing
  • PS Analytical Sir Galahad mercury analyzer
  • Tekran mercury analyzer
  • BIOS gas flow calibrator
  • Gilibrator gas flow calibrators
  • Porter mass flow controllers
  • Bench-scale test cells
  • TSI tri-jet aerosol generator
  • TSI aerodynamic particle sizers
  • TSI condensation particle counters
  • Leeman PS200 automated mercury analyzer
  • DMA 80 coal and ash mercury analyzer
