ATLANTA An innovative mercury control technology being tested by Southern Company, the Electric Power Research Institute (EPRI) and eight other project partners, has won a R&D 100 Award. The technology, developed by ADA-Environmental Solutions (ADA-ES), is part of a Department of Energy (DOE) field-testing project to assess the long-term performance and reliability of activated carbon injection in removing mercury from the flue gas of coal-fired power plants.
The R&D 100 award, presented by R&D Magazine, recognizes the top 100 most technologically significant products of the year. Southern Company is testing the advanced mercury control technology at its E.C. Gaston electric generation plant, which is owned and operated by the companys Alabama Power subsidiary.
As part of the process, activated carbon and potentially other materials, known as sorbents, are injected upstream of an existing baghouse system designed to collect flyash. These sorbents adsorb the mercury, which could result in substantial emissions reduction. The process of injecting sorbents, such as activated carbon, for mercury control before a baghouse but after an electrostatic precipitator is an EPRI-patented process called TOXECONTM.
This award recognizes significant technological efforts being made to reduce mercury emissions, said Charles Goodman, senior vice president of research and environmental affairs for Southern Company. Were proud that our efforts to advance the technology are being recognized. We believe it will prove beneficial as the industry seeks cost-effective, efficient ways to control mercury emissions.
Plant Gaston was the site chosen by DOE for the nations first full-scale mercury control testing in 2000. The initial work on the technology was completed in 2001, with an average mercury reduction of 80 percent achieved. Last year, Plant Gaston was selected by the DOE to continue testing the mercury control technology. Second-phase testing began in April of this year.
Winning this award is a tribute to the diligent efforts and expertise of the ADA-ES engineering staff and its partners, said Dr. Michael Durham, President of ADA-ES. It recognizes the success in advancing the technology from pilot-scale to the extremely challenging large-scale power-plant application.
Southern Company and Alabama Power are working with ADA-ES, EPRI, Alleghany Energy, Arch Coal Inc. (ACI), Duke Energy, FirstEnergy, Hamon Research-Cottrell, Ontario Power Generation and TVA. DOE funds 55 percent of the $2.1 million project cost, with Alabama Power and the other participating companies co-funding the remaining 45 percent.
