Mercury

• 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.

Principles 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

Tunable 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

Tunable 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

20
Tunable 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

Interaction Between NH3 and HCl

• Detached Plume
• Phenomenon which occurs from the formation of
  ammonia salts due to the cooling of NH3 and HCl

NON-COMPLIANT OPACITY PROCESS MONITOR
37
CEMTEK 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.
