What’s New?


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

Mercury in sample gas is pre-concentrated onto (pat’d) 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

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

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



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


NH3 + HCl → NH4CL

NON-COMPLIANT OPACITY PROCESS MONITOR

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.
