April 15, 2010 Subject: Meeting with Representatives of GEA Bischoff Location: U.S. Environmental Protection Agency, Research Triangle Park, NC Date: April 15, 2010 Participants:GEA Bischoff Charles Leivo, President and CEO, GEA Bischoff, Inc. Nathan Blanton, Sales Engineer, GEA Bischoff, Inc. Andreas Palinski, Senior Sales &Process Engineer, GEA Bischoff, GmbH US Environmental Protection Agency Keith Barnett, Sector Policies and Programs Division (SPPD) Susan Fairchild, SPPD Nick Hutson. Office of Research and Development Frank Pronciotta, EPA Office of Research and Development RTI International Mike Laney Representatives of GEA Bischoff presented anoverview of GEA Bischoff and the types of emissions control work their company performs, including their work with cement manufacturing plants. Recent scrubber installations include a Lafarge cement plant in Dunbar, GB and one at Lehigh in Mason City, Iowa. Designs and issues inthe application of scrubbers for the control of HCl, SO2and mercury were discussed. In addition to the cement industry, Bischoff provides emissions control solutions for the glass, catalytic cracking,iron and steel, and energy recovery industries. Information on their control technologies is attached. Other comments from the meeting: • GEA has installed 7 wet scrubbers in the cement industry. The most recent installation uses EPA dust and raw mill dust as the reagent (Dunbar, Scotland). • Recently installed a low dust SCR system after an ESP/Bag Filter – Waldorf Cement – it begins operation next year.
