Babcock & Wilcox Power Generation Group, Inc. (B&W PGG ) researchers said they successfully captured carbon dioxide (CO2) emissions from a pilot-scale, coal-fired boiler using advanced solvents and a proprietary CO2-capture process developed at the company's research center in Barberton, Ohio.
B&W PGG has conducted its first demonstration on flue gas from a coal-fired boiler at the company's Regenerable Solvent Absorption Technology (RSATTM) Pilot Plant. Researchers were able to continuously remove more than 90 percent of the CO2 from the Small Boiler Simulator II's flue gas stream using a fully integrated RSAT process. B&W PGG researchers are now evaluating proprietary solvents and characterizing their performance at this scale.
The RSAT process uses a liquid solvent in an absorber vessel to remove CO2 from a plant's flue gas stream. The CO2 can then be removed from the solvent and prepared for long-term storage or other uses, such as enhanced oil recovery, while the solvent is recycled and reused.
Pilot-scale testing of solvents began at the B&W Research Center in June 2009 and will continue throughout 2010.
B&W PGG is an operating unit of The Babcock & Wilcox Company.
