Fabrication of a Full-Scale Sorbent Activation Process for Mercury Control

Chemical engineers from the Illinois State Geological Survey (ISGS) worked with engineers from Apogee Scientific, Inc., EPRI, and Maxwell Consultant and Engineering to design a full-scale sorbent activation process (SAP) unit. The SAP unit will be used for on-site production of activated carbon from Illinois coal at Ameren's Meredosia power plant during September through December 2008. The Engineering design data were obtained from the Applied Research Laboratory at the ISGS using a bench-scale SAP unit. ISGS engineers are currently providing technical assistance to Heat Transfer Specialists, Pekin, Illinois, to fabricate the SAP unit. A meeting is planned for May 22, 2008, at Meredosia to discuss the planned full-scale mercury control tests. SAP is a state-of-the-art, patented technology developed at the ISGS. This one-of-a-kind technology is expected to reduce the cost of mercury control removal from coal power plants by more than 50%.
