Coal-Fired Carbon Dioxide Emissions Seen As More Complicated
Posted on: Friday, 16 September 2005, 21:00 CDT
Sep. 16--While capturing and reusing carbon dioxide from fertilizer plants is believed to improve both oil production and the environment, a far greater benefit would be felt if emissions could be recycled from coal-fired power plants, researches say.
Emissions from fertilizer plants are nearly pure carbon dioxide that can be dumped directly into pipelines, but coal-fired power plant emissions also contain nitrous oxides, sulfur oxides and other noxious chemicals that must be separated before the carbon dioxide can be transported.
"Separating the carbon dioxide from coal plants is technically feasible, but it's currently cost-prohibitive," Oklahoma Energy Secretary David Fleischaker said. "If we can conquer or solve that problem, it would pave the way for utilizing our huge coal supply and reducing significantly the worry we have about environmental damage related to coal."
Making such technology more affordable is one of the goals of the Southwest Regional Partnership on Carbon Sequestration -- a group of researchers, power plant operators and other industry players throughout the region who investigate various options for how best to minimize carbon dioxide emissions.
Oklahoma Gas and Electric Co., the state's largest electric utility and the state's largest user of coal, is a member of the carbon partnership.
"We have been involved for more than a year in trying to find methods of separating and capturing carbon dioxide and other emissions for projects including oil production," OG&E spokeswoman Sondra Longcrier said. "We continue to work toward that goal."
