The Linde Group and BASF have successfully completed a joint pilot project to improve the capture of carbon dioxide (CO2) from flue gas at a coal fired power plant at the National Carbon Capture Centre (NCCC) in Wilsonville, Alabama.

By pooling their technologies, the industrial gas giant and the world’s leading chemical company captured more than 30 tonnes of CO2 per day at a capture rate of more than 90% in the Wilsonville project. In addition, the purity of the captured CO2 was more than 99.9%.

The technology used during the scheme combined Linde’s CO2 capture process and engineering with BASF’s advanced aqueous amine-based solvent and process technology. Operating at the NCCC facility for more than 1,200 hours, the pilot plant withstood higher regeneration pressure of 3.4 bar absolute.

The result should prove that CO2 capture is economically feasible, substantially reducing emissions and their negative impact on climate

Dr. Andreas Northemann, Vice-President of BASF’s OASE Gas Treating Excellence, explained the advantages of his company’s technology, “The amine-based OASE blue technology offers significant benefits for CO2 capture as it aims to reduce the regeneration energy requirements using novel solvents. Long-term pilot testing demonstrated the solvents’ performance and stability.”

Dr. Christian Bruch, Member of the Executive Board of the German corporation, signified, “The result should prove that CO2 capture is economically feasible, substantially reducing emissions and their negative impact on climate.”

Based on this positive achievement, the Tier One player and BASF will begin larger-scale testing and will explore potential commercial opportunities.

“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,” Northemann confirmed.

 

Under a cooperative agreement with the US Department of Energy’s (DOE) National Energy Technology Laboratory (NETL), the project has been operating the pilot plant at the site since January 2015.
