Progress on Mercury Removal Continues According to the Presenters on October 25

 

A second Hot Topic session in the afternoon focused on mercury control technologies. Steve Derenne of We Energies spent the morning observing the performance of the Presque Isle TOXECON system. Then on the way back to Milwaukee he stopped to admire the fall colors and give a presentation via cell phone to some 40 participants. The system is able to remove 90 percent or more of the mercury with relatively few problems. There is some dust generation when the pin mixer starts wetting the disposed carbon, but this is momentary. UCC is working on a solution including possibly using foam on startup.

 

Luke Wilkinson of Indigo Technologies stayed up late in the night in Australia to give his presentation only to remember that it was at 1:00 p.m. rather than 9:00 a.m., so he got a few hours sleep before he described the latest successes with the Indigo Agglomerator.  Testing at the Watson plant has shown that injection of activated carbon leads to the 25 ton per year additional stack emissions which can trigger NSR. The use of the agglomerator avoids this problem and actually aids in the mercury removal.

 

Sid Nelson of Sorbent Technologies affirmed the success of brominated carbons for high mercury removal. The concrete friendly version allows the flyash to be sold. A new plant is up and running and another is underway.

 

Sharon Sjostrom of ADA-ES provided up-to-date data on the latest testing of various sorbents. ADA has a large number of systems under design. They have progressed on the project to build a carbon manufacturing facility to the point where they are purchasing equipment.

 

Rob Nebergall of Norit provided an update on the carbon supply sources and capacity. He indicated that research is continuing on a number of fronts including brominated and concrete friendly carbons.

 

There was a brief discussion of the ability of the HCl pre-scrubber to achieve efficiency as high as 99.7 percent. An extensive analysis of this technology is found in the FGD Decision Tree at
