The University of North Dakota Energy and Environmental Research Center (EERC), in partnership with the North Dakota Industrial Commission, ALLETE Clean Energy, Minnkota Power Cooperative, Mitsubishi Heavy Industries (MHI), and Burns & McDonnell, will perform a pre-front-end engineering and design (pre-FEED) analysis and cost estimate for retrofitting MHI’s Kansai Mitsubishi Carbon Dioxide Recovery (KM-CDR™) amine-based post-combustion carbon dioxide (CO₂) capture process with an existing coal-fired generating unit. The commercially available KM-CDR process uses an advanced amine solvent, KS-1™, that exhibits less solvent degradation, a lower solvent circulation rate, higher working capacity, and reduced steam consumption for regeneration compared to monoethanolamine (MEA). The solvent technology has shown reliable, cost-effective operation at bench and pilot scale (up to 25 MWe), routinely achieving 90 percent CO₂ removal, and also operates at commercial scale, capturing approximately 1.6 million tonnes of CO₂ per year from a 240-MWe sub-bituminous coal-derived flue gas stream at the W.A. Parish Plant in Thompsons, Texas, through a U.S. Department of Energy (DOE)-funded project with Petra Nova Parish Holdings, LLC. Through these development efforts, several improvements to the process have been implemented, including a novel flue gas quencher and absorber design for lower capital costs and ease of construction and an amine wash section for minimizing aerosol emissions from treated flue gas. This project will address challenges associated with a full-scale system, such as the use of lignite coal, effects from cold climate, treating higher quantities of flue gas, and application of heat integration. The team will design a fully integrated KM-CDR system for installation at Minnkota’s Milton R. Young Station Unit 2 (MRY2) near Center, North Dakota; perform testing with EERC’s slipstream baghouse installed at MRY2 to evaluate aerosol emissions; evaluate the KS-1 solvent on lignite coal-derived flue gas to refine critical design parameters; complete a techno-economic assessment in accordance with DOE’s bituminous baseline study; and complete a pre-FEED analysis and cost estimate of the system at MRY2.
