1 February 2010-- Researchers with Babcock & Wilcox Power Generation Group have began capturing carbon dioxide (CO2) from a pilot-scale, coal-fired boiler at the company’s research center in Ohio.
Researchers said they were able to remove 90 percent of CO2 from flue gas at a coal-fired boiler at the Regenerable Solvent Absorption Technology (RSAT) pilot plant. The RSAT process uses a liquid solvent in an absorber vessel to remove CO2 from the flue gas stream. The gas can then be removed from the liquid and prepared for long-term storage or other uses, such as enhanced oil recovery, while the solvent is recycled and reused.
Testing is expected to continue throughout 2010.
