Configurations
Regulated Emission Source Configuration (Utility, Industrial, Cement)
The Tekran® 3300 Hg-CEM was designed as an integrated system for mercury emission monitoring of regulated point sources. The primary components are housed in an instrument rack, typically located in a controlled environment at ground level. A heated line extends to Model 3342 Probe (M&C SP2600, non-inertial) located at the stack sampling point. The Tekran® Model 3305 CEM Controller provides continuous operation, periodic calibrations and data reporting. The Tekran® 3310 (Elemental) and 3315 (Ionic) Mercury Calibrators provide the required NIST traceable calibration gases. The Tekran® 2537S detector, based on pure gold pre-concentration and cold vapor atomic fluorescence, combined with the 3320 Sample Conditioner, is the proven performance leader for today’s low-level (<1 ug/m3) flue gas mercury monitoring.
Pilot Plant Research Configuration
Many Tekran® 3300 systems have been deployed for research purposes. In fact, the US EPA purchased 3 complete Tekran® 3300 systems for their mercury flue gas research work. Many such systems are being used for mercury control technology development or evaluation. Depending on the research needs and goals, the Tekran® 3300 can be customized. An example of a research configuration used on a pilot plant is shown, with probe, heated line, sample conditioner, detector, elemental calibrator, oxidized Hg calibrator and PC controller.
Bench-Scale Mercury Abatement Technology Configuration
The Tekran® R&D team has developed a number of custom configurations for mercury abatement research companies. In order to develop mercury control technology, high quality measurements are required at the bench scale using simulated flue gas. For research studies the 3320 Local-Diluter option provides a scaled down version of our full Hg-CEM system. Using the Local-Diluter option, the 3320 can directly accept particle free process gas stream and provide continuous high frequency total and speciated mercury results. In the example configuration shown, The Tekran® 3310 Elemental Hg Calibrator and 3315 Oxidized Hg Calibrator provides a known input of mercury upstream to test the installed abatement technology.
