27 April 2006 -- Powerspan Corp. and Ameren Corp. subsidiary AmerenUE today announced plans to pilot test a new mercury removal process at AmerenUE's Rush Island Power Plant in Jefferson County, Mo. The technology, called Photochemical Oxidation, or PCO, uses ultra-violet light to oxidize and remove mercury from coal-fired power plants. Pilot testing at the Rush Island plant is scheduled for late 2006.
The primary objective of the PCO pilot test program is to demonstrate the oxidation of elemental mercury in a coal flue gas stream using ultra-violet light and the subsequent capture of the mercury in various particle collection devices, including wet and dry electrostatic precipitators and fabric filters. In addition to the field testing, preliminary cost estimates for full-scale commercial applications will be developed.
"If successfully demonstrated, PCO represents a straight-forward, cost-effective approach to controlling mercury emissions from power plants, particularly those that burn lower rank coals," said Powerspan chairman and CEO Frank Alix. He added, "We look forward to working with AmerenUE, which has distinguished itself as a leader in using innovative technologies for reducing other power plant emissions."
"Ameren prides itself on being an industry leader in seeking innovative ways to reduce emissions from coal-fired power plants," said Ameren Chief Operating Officer Tom Voss. "This project allows us to continue that tradition while helping to develop technologies that will play a part in meeting the new requirements for mercury emissions."
Grant funding for the project is provided by the U.S. Environmental Protection Agency, Region VII, through the Missouri Department of Natural Resources' Air Pollution Control Program. Additional funding is provided by AmerenUE and Powerspan.
