3Mercury
- Regulations, where do we stand?
- Since vacating the Clean Air Mercury Rule (CAMR),
the implementation of mercury monitoring has
primarily fallen on the state and local
regulators. - The EPA often uses Consent Decrees to mandate
mercury monitoring. - The cement industry is currently under review by
the EPA to slash mercury emissions.

9Principles of Operation
Tekran Instruments
- Mercury in sample gas is pre-concentrated onto
(patd) pure gold cartridge - Adsorbed mercury is thermally desorbed
- Detected by atomic fluorescence detector
- Two cartridges are used to alternately sample and
desorb allowing continuous operation - No gaps in data stream

17Tunable Diode Lasers
What are Tunable Diode Lasers?
- Small crystals of Ga, As, Sb, P
- Similar to those used in telecommunications, CD
players, and laser printers - Emits laser radiation when an electric current is
applied - Laser center wavelength depends on composition of
crystal - Wavelength can be changed over a narrow range by
changing current, or over a wider range by
changing laser operating temperature - Permits scanning over entire absorption feature

19Tunable Diode Lasers
Practical Applications for the TDL
- SCR/SNCR Ammonia Slip Monitoring
- Compliance
- Single Point Monitor
- Internal Audit Cell
- Daily span checks meet regulatory requirements
- Process Control/Feedback
- Multi-point arrays with single analyzer
- Multiplexed signal allows for multiple monitoring
points in dust laden processes - Useful for SCR tuning and monitoring catalyst bed
degradation over time
20Tunable Diode Lasers
Practical Applications for the TDL
- HCl Monitoring
- Waste-to-Energy Applications
- Plastics in fuel stock form HCl during combustion
process - Wood-fired Boiler Applications
- Logs transported to lumber mill Cogen and Power
plant facilities can absorb salt (NaCl) when in
contact with salt water during transport and form
HCl during combustion process

NON-COMPLIANT OPACITY PROCESS MONITOR
37CEMTEK Instruments Model 6000 6010
- Many Plants have multiple Boiler configurations
feeding into a main stack. Individual Boiler
outlets allows for the determination of any
emissions violation at the source. - Multi-Unit applications can utilize non compliant
opacity monitors to detect individual excursions
seen as an overall increase with the Stack
Monitor. Accurate measurement of individual
boiler opacity may avoid any excursion over the
permitted limit imposed on the plant since
detection at the onset of incomplete combustion.
Energy reduction measures are incrementally
reduced as the opacity stays below a preset
threshold.
