Wilsonville, Ala., June 7, 2011 — Researchers at the National Carbon Capture Center have successfully commissioned a new test center for evaluating improved technologies for capturing carbon dioxide from coal-based power plant flue gas.
The new center, the Post-Combustion Carbon Capture Center (PC4), is a part of the larger NCCC — a national testing and evaluation center established by the U.S. Department of Energy and operated and managed by Southern Co.
The highly flexible PC4 test center was established to test carbon capture under a wide range of operating conditions using flue gas from an actual pulverized coal power plant.
During initial testing at PC4, which began in March, a pilot solvent test unit was successfully operated on flue gas from a large coal-fired power plant using a carbon capture solvent called monoethanolamine, a baseline reference solvent.
NCCC researchers are determining baseline carbon capture performance of the new test center in anticipation of future tests. So far, capture efficiency of the pilot solvent test unit consistently exceeded the expected 90 percent capture for which the post-combustion unit was designed and is now in steady operations capturing about ten tons per day of carbon dioxide, with a total of about 420 tons captured to date.
Other carbon capture solvents from technology developers worldwide will be tested at the PC4 and compared with the MEA baseline data. To date, the NCCC has entered into testing agreements with Aker Clean Carbon AS and Babcock & Wilcox Power Generation Group, Inc., for evaluation of advanced CO2 capture processes at PC4. Both companies plan to conduct testing of their respective technologies at the NCCC later this year.
ACC of Norway has 18 years of experience in the carbon capture field in Europe. The company plans to test a process for capturing carbon from power plant flue gas that will utilize advanced amine solvents. Process advancements developed by ACC are expected to both reduce cost and improve environmental performance over conventional technology.
B&W will also conduct research at the NCCC to further develop commercially viable methods of reducing carbon emissions from coal-fired power plants. The company will test its Regenerable Solvent Absorption Technology process and OptiCap advanced solvent.
