Sorbent Traps vs. Mercury CEMS Webinar - Hot Topic Hour May 8, 2014
The Hot Topic Hour yesterday included an extensive and friendly debate over the results of sorbent traps and mercury CEMS. The differences of opinion were about gaseous mercury measurement.

Jim provided the following comparison between CEMS and Sorbent Traps - Method 30B includes HgP, which results in overestimation of gaseous Hg that may be significant at MATS Hg levels but not enough to impact RATA pass or fail Differences in HgT up to about 0.50µg/Nm3 (typically less, but sometimes more) may be explained by HgP when controlling Hg with ACI and/or Br. Will vary somewhat by coal Hg levels, PM emissions, ACI injection, etc. Bromine “interference” should not be a concern except possibly under extremely high furnace Br injection rates and is not a concern for brominated activated carbon.

Measuring Ammonia Slip from Post Combustion NOx Reduction Systems
In many facilities there may be room for process improvement that could reduce operating costs or provide revenue enhancement opportunities. Operating SNCR or SCR technology closer to its limit offers these benefits but increases the risk of high ammonia slip. The risk could be abated with the use of ammonia monitoring technology. But, except for gas-fired plants, continuous ammonia slip monitoring technologies have not been available at a practical price to facilitate these cost-saving or revenue enhancing improvements. Conditions that exist in high dust, high temperature, high NOx and/or high SO2 environments make most analyzer methods of continuously measuring ammonia unsuitable for application to coal plants. An overview of the technologies available for measuring ammonia in the high dust region downstream of a Nox reduction system and the status of their development is provided.

Constellation Energy installed SNCR systems at the CP Crane Station, units 1 and 2. These SNCR systems use continuous ammonia slip analyzers that work on the principle of tunable diode laser (TDL) spectroscopy and provide continuous, real-time indication of ammonia slip in the duct. These analyzers facilitated optimization of the SNCR system to avoid high ammonia slip transients that are the principal contributors to downstream problems normally associated with ammonia slip.
