BASF recently announced it has completed a joint pilot project with The Linde Group to improve capture of carbon dioxide (CO2) from flue gas at a coal fired power plant at the National Carbon Capture Center (NCCC). The NCCC is a U.S. Department of Energy (DOE) research facility managed and operated by Southern Co. in Wilsonville, Ala.
The technology used during the pilot project reportedly integrates BASF’s advanced aqueous amine-based solvent and process technology. Testing confirmed the main performance targets set for the facility. Specifically, it captured more than 90% CO2 from the flue gas, while the purity of the CO2 was more than 99.9%. The design capacity of the operation was up to 1.5 Megawatt-electric (MWe) and required less than 2.8 gigajoules of regeneration steam per metric ton of CO2. The NCCC includes a post-combustion carbon capture facility that reportedly allows testing and integration of advanced technologies using actual coal-derived flue gas from an 880-MW pulverized coal unit at Alabama Power’s Plant in Gaston. The pilot plant has operated at the facility for more than 1,200 hours at a higher regeneration pressure of 3.4 bar absolute, thereby reportedly demonstrating a cost advantage over other amine-based technologies.
“The amine-based OASE blue technology offers significant benefits for CO2 capture as it aims to reduce the regeneration energy requirements using novel solvents,” said Andreas Northemann, Ph.D., vice president of BASF’s OASE Gas Treating Excellence. “Long-term pilot testing demonstrated the solvents’ performance and stability. BASF’s almost 50 years of experience in industrial gas treating, combined with the expertise of Linde in large-scale engineering, procurement and construction, will lead us to the commercial scale-up of OASE blue technology.”
