Linde LLC (Linde) and partners will design, build, and operate a 1 megawatt electric (MWe) equivalent pilot plant at a PC plant host site to further refine a post-combustion capture solvent technology developed by Linde and BASF incorporating BASF’s novel amine-based process along with Linde’s process and engineering innovations. This technology offers significant benefits compared to other solvent-based processes as it aims to reduce the regeneration energy requirements using novel solvents that are stable under coal-fired power plant feed gas conditions. BASF has developed the desired solvent based on the evaluation of a large number of candidates. Linde has evaluated a number of options for capital cost reduction in large engineered systems for solvent-based post-combustion capture technology. A techno-economic assessment will be performed for a conceptual 550 MWe coal-fired power plant incorporating the amine-based post-combustion CO2 capture technology in development. Results from previous bench-scale and small pilot testing will be analyzed and design optimization studies will be performed to select the slipstream pilot plant design basis. The basic design will be completed with sufficiently detailed engineering to accurately estimate the cost of the slipstream pilot implementation. The techno-economic analysis and the slipstream pilot plant cost estimates will be used to confirm project feasibility and progression to the next stage. Based on completed detailed engineering studies and design development for the system, the pilot plant will be constructed, installed, and commissioned to operate on a slipstream of coalfired flue gas. The National Carbon Capture Center (NCCC) in Wilsonville, Alabama, will be the host site for the slipstream pilot plant. Parametric testing will be conducted to confirm that the pilot plant meets the performance targets and to obtain appropriate design information. A detailed data analysis will be performed to assess and develop the design basis for scale-up. The pilot plant will be operated continuously under stable conditions to confirm the solvent stability and key material compatibility. The long-term test results will be used to update the techno-economic study and develop a commercialization plan for this technology.
Program Background and Project Benefits
The mission of the U.S. Department of Energy/National Energy Technology Laboratory (DOE/NETL) Existing Plants, Emissions, & Capture (EPEC) Research & Development (R&D) Program is to develop innovative environmental control technologies to enable full use of the nation’s vast coal reserves, while at the same time allowing the current fleet of coal-fired power plants to comply with existing and emerging environmental regulations. The EPEC R&D Program portfolio of post- and oxy-combustion carbon dioxide (CO2) emissions control technologies and CO2 compression is focused on advancing technological options for the existing fleet of coal-fired power plants in the event of carbon constraints. Pulverized coal (PC) plants burn coal in air to produce steam and comprise 99 percent of all coal-fired power plants in the United States. CO2 is exhausted in the flue gas at atmospheric pressure and a concentration of 10 to 15 percent by volume. Post-combustion separation and capture of CO2 is a challenging application due to the low pressure and dilute concentration of CO2 in the waste stream, trace impurities in the flue gas that affect removal processes, and the parasitic energy cost associated with the capture and compression of CO2. Chemical solvents can be used to capture CO2 from flue gas by absorbing it into a liquid carrier. Research has been ongoing to identify new, next generation solvents. Slipstream testing and validation of promising solvents along with innovative post-combustion capture processes can make significant progress toward increasing the energy efficiency and consequently reducing the cost of CO2 recovery from coal-fired power plants. Establishing the capability of this novel, post-combustion CO2 capture technology at the pilot plant scale can provide the first steps toward commercialization and achieve significant reductions in the cost of electricity (COE) of large-scale power plants, thereby working toward the achievement of the DOE goal of 90 percent CO2 capture with less than 35 percent increase in COE. Project Goal
The overall goal of the project is to conduct a pilot plant test of the Linde-BASF post-combustion capture technology— incorporating BASF’s novel amine-based process —on a slipstream of flue gas at a coal-fired power plant host site to confirm that it can meet DOE performance targets. Objectives
The project objectives are to (1) demonstrate the benefits of the novel, amine-based, post-combustion CO2 capture process technology by performing a techno-economic analysis on a 550 MWe coal-fired power plant incorporating CO2 capture; (2) design, build, and operate a 1 MWe equivalent slipstream pilot plant to treat flue gas from a coal-fired power plant; and (3) perform parametric and long-duration tests and complete data analysis and an updated techno-economic analysis to demonstrate that the technology meets performance and cost targets.
