Linde LLC is designing, constructing, and testing a pilot-scale (1 MWe), post-combustion carbon dioxide (CO2) capture plant using a novel amine-based solvent.  Today, solvent based technologies are the leading option for post-combustion CO2 capture from large coal-fired power plants, as they have been applied in other applications on a large scale. However, a number of challenges exist in the use of traditionally available solvent-based technologies, including the need for very large-scale implementation, significant parasitic energy losses, and solvent stability and degradation issues.  This project's solvent-based process aims to reduce regeneration energy requirements by using novel solvents that are stable under the coal-fired power plant feed gas conditions.

The 1 MWe pilot plant unit will be tested at the National Carbon Capture Center (NCCC) using a flue-gas slipstream from the coal-fired power facility located in Wilsonville, Alabama.  Following the pilot tests, data analysis will be performed to confirm that the technology meets key performance targets and that plant operation is stable during long-duration operation.  The data from the pilot plant will be used to update a preliminary techno-economic analysis for a 550-MWe coal-fired power plant with carbon capture, and to confirm the benefits of the post-combustion CO2 capture technology.
