Bench-scale investigation of various multi-pollutant control strategies with simulated coal combustion flue gas is the main research focus in the Emissions Control Lab.
Coal flue gas composition is accurately represented by metering, mixing and preheating various constituents. A bench-scale wet scrubber vessel can be connected along the flue gas path to investigate:
- Removal of oxidized mercury (Hg2+) and sulfur dioxide (SO2) by wet scrubbers
- Re-emission of elemental mercury (Hg0) from wet scrubbers
- Selenium speciation and control in wet scrubbers
- Wet scrubber additives for multi-pollutant removal
- Fundamental gas-liquid scrubbing concepts
A gas-solid catalytic reactor can also be operated with the simulated flue gas over a wide range of temperatures and space velocities. Specific applications of this system include:
- Catalytic oxidation of elemental mercury (Hg0)
- Catalytic reduction of nitrogen oxides (NOx) and ammonia (NH3)
- Catalyst deactivation and regeneration studies
Catalyst pellet samples for laboratory and slipstream field tests are prepared using a Mix-Muller and extrusion system.
