Mitsubishi Heavy Industries America has successfully completed construction in the US of what it deems the world's largest post-combustion CO2 capture and compression system, using technology it previously successfully deployed in projects for capturing emissions from both natural gas and oil combustion.
The system is based on MHI's proprietary KM CDR process and high-performance KS-1 amine solvent which was jointly developed by MHI and Kansai Electric Power, the company said in a statement. It captures CO2 from a 240 MW equivalent coal exhaust slipstream from unit 8 at NRG Energy W. A. Parish coal-fired generating station in Thompsons, Texas, and is rated at 4,776 metric tons per day of CO2 captured.
MHIA, together with MHI, licensed and provided the KM CDR process and KS-1 solvent and delivered overall system design services, engineering, procurement for major system equipment, operator training, and commissioning support.
The CO2 capture and compression system at the W.A. Parish coal-fired generating station is part of the Petra Nova Carbon Capture Project which is jointly promoted by NRG and JX Nippon Oil & Gas Exploration Corporation. Captured CO2 will be transported through an 81-mile pipeline and used for enhanced oil recovery at the West Ranch Oilfield, located on the Gulf Coast of Texas.
