Summary •A unique sorbent material, carbon polymer composite material (CPC), has been developed for flue gas mercury and other contaminates removal •The CPC material is deployed in a stationary sorbent bed applications, and the sorbent bed does not require a frequent regeneration process •Field demonstration tests have shown that the CPC bed is effective for Hg/SOx removal (in coal-fired power plant after a wet scrubber) for long-term (4-5 months without requiring frequent regeneration or maintenance processes) •We will perform a preliminary engineering economic analysis is to assess the feasibility of retrofitting the CPC to the existing power plant and cost, and conduct a medium scale field demonstration this year, and a full-scale field demonstration afterward W.L.

John Darrow, Associate at W. L. Gore & Associates, Inc., discussed expanded polytetra-fluoroethylene (ePTFE) based products that could provide solutions to new compliance challenges for PM, dioxin/furan (D/F) and mercury. There was a summary of the potential for ePTFE membrane filter bags for PM control, REMDIA catalytic filtration systems for D/F control and a new carbon polymer composite material for mercury control. The composite material was of great interest to the participants who asked about pressure drop (low), efficiency (70-90 percent in addition to the scrubber removal) and elemental mercury removal (high). Testing is taking place at the Southern Yates station with EPRI also involved. This technology could be used as a second step if the initial attempt to remove mercury in the scrubber falls short. Since this device follows the scrubber it is better suited for a plant with a scrubber. Activated carbon would be injected ahead of the scrubber and would have the effect of reducing the amount removed in the scrubber. Therefore large amounts of carbon would be required to gain small efficiency increases.

Utility MACT – Impact and Compliance Strategy Webinar - Hot Topic Hour February 17, 2011
The Utility MACT is moving forward and the proposal is being reviewed by OMB. It will require substantial investments over the next few years. This coincides with investments by industrial boiler owners and cement plants, so the available resources may be strained. Presentations on Thursday covered the regulations, the analysis required and the control technology.

John Darrow, Energy Market Specialist at W.L. Gore & Associates, Inc., described the characteristics of ePTFE membrane filter media and compared them to other media available. He said that 35 EGUs were now using this material. However, because of higher material cost, it was not necessarily the best solution for every power plant. He described a four-step process to go through to determine what the best media would be for a specific power plant to achieve the objective – “Getting the Lowest Annualized Cost w/o Emissions Problems.”

Fabric Selection for Coal-fired Boilers Webinar - Hot Topic Hour October 28, 2010
A large group of attendees heard five very good presentations related to the selection of the best filter media to meet the various coming regulations for PM2.5. Attendees agreed that the fundamental filtration capability of the vast majority of fabrics available today, as measured by laboratory tests, far exceeds any existing or expected emission control requirement and the performance of many is below the minimum detectable limit of the test methods. Several presenters pointed out that while the results of these evaluations can be a good guide for filter efficiency and pressure drop, the actual performance of filter material will rarely achieve the levels seen in these tests. This is because the actual performance is dependent on many factors related to the specific site conditions. This causes a concern in the industry that regulators will assume that lab test results are indicative of actual performance and expect the same performance at every installation. Dr. McKenna indicated that because filter media performance was so good, future enforcement will most likely be focused on plant baghouse O&M. He also stated that it will be important to demonstrate what aspects of O&M plans are practical and valuable, so that regulators do not make these plans an operational nightmare.
