TDA Research, Inc. is advancing their sorbent-based post-combustion carbon dioxide (CO2) capture process by designing and building a pilot-scale unit and testing it with a 0.5-MWe slipstream of flue gas at the National Carbon Capture Center (NCCC). TDA’s process is based on an alkalized alumina adsorbent that uses low-pressure steam for desorption and operates at near atmospheric pressure, reducing the cost of CO2 capture compared to commercially available amine-based and other solid sorbent-based systems. Previous bench-scale testing of the process using real coal-derived flue gas showed that TDA’s sorbent can achieve greater than 90 percent CO2 capture with stable CO2 loading. In this project, TDA’s sorbent-based process will be tested at NCCC under realistic conditions for continuous long-term operation to evaluate the technical and economic feasibility of the technology for further scale up. Parametric testing will be conducted for 1.5 months to determine the optimum operating conditions and steady-state testing will be performed for a minimum of 2 months. Scale-up production of the sorbent will also be performed. A detailed techno-economic analysis based on integration with a nominal 550-MWe power plant will be completed based on pilot-scale test results.
Predecessor Project: DE-NT0005497
TDA Research’s novel sorbent-based post-combustion CO2 capture technology combines a low-cost adsorbent, low-regeneration energy requirements, and a well-optimized and integrated process that reduces capital and operating costs and increases system efficiency. Small pilot-scale testing validates the economic viability of the technology and promotes future scale-up of the process. Improving the economics of CO2 capture, utilization, and storage enables environmentally responsible energy production from abundant domestic coal.
