B&W PGG has conducted its first demonstration on flue gas from a coal-fired boiler at the company’s Regenerable Solvent Absorption Technology (RSAT) pilot plant. The company claims that its researchers were able to remove more than 90% of the CO2 from the small boiler simulator II’s flue gas stream using a fully integrated RSAT process. The 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 oil recovery, while the solvent is recycled and reused.
Richard Killion, president and chief operating officer of B&W PGG, said: “This is a major milestone in B&W PGG’s research and development of carbon-capture technologies for fossil-fuel fired power plants.
“These tests reinforce our belief that the RSAT process offers substantial promise as an economical and efficient post-combustion CO2-capture technology and that B&W PGG is a leader in this important field.”
Pilot-scale testing of solvents began at the B&W research center in June 2009, and will continue throughout 2010.
