In this Small Business Innovation Research/Small Business Technology Transfer (SBIR/STTR) Phase I project, TDA Research, Inc. (TDA), in collaboration with Membrane Technology Research Corporation (MTR) and the University of California–Irvine are developing a low cost, high capacity sorbent that will integrate into a hybrid membrane-sorbent post-combustion carbon capture system to remove carbon dioxide (CO2) from coal-fired power plant flue gas. The system will integrate a membrane module and a sorbent capture system in a two-step CO2 separation process. The project will focus on system integration and process design, building on previous research conducted separately on MTR’s two-stage membrane CO2 capture process and TDA’s sorbent CO2 capture process.

The research team will conduct a preliminary process simulation to identify the optimum conditions for the membrane-sorbent hybrid carbon capture system that will ensure the highest power plant efficiency. Bench-scale experimentation will be conducted to verify the performance of the components under relevant operating conditions. The sorbent formulation will be optimized for the hybrid system, and testing will include an assessment of the effect of flue gas contaminants on the sorbent. The best-performing sorbents will undergo long-term durability testing with a minimum of 5,000 consecutive adsorption/regeneration cycle tests run under simulated operating conditions. The research team will conduct a preliminary design of the hybrid CO2 capture system—including all supporting equipment—based on performance data, and complete a technical and economic assessment of the hybrid CO2 capture technology based on DOE guidelines. Successful development of the membrane-sorbent hybrid post-combustion carbon capture system will provide a cost-effective way to control CO2 emissions from existing coal-fired power plants.
