Novel Solid Materials and Processes for CO2 Capture from Cogeneration Flue Gas

点击翻译按钮获取中文摘要

A significant (>90%) source of CO2 emissions in the energy sector is power and steam production from the efficient use of combined heat and power (cogeneration) from natural gas. Current technologies for large-scale CO2 capture from cogeneration flue gas are unattractive due to the relatively low (4-6 %) concentration of CO2, leading to high operating and capital costs. The unique composition of cogeneration flue gas requires innovative materials and process development strategies. The underlying goal of this partnership with Canadian Natural Resources Limited (CNRL), Suncor Energy, InnoTech Alberta, and Fluor Canada Ltd. is the development and de-risking of an adsorption-based technology to capture CO2 from cogeneration flue gas. Through this alliance, some of the largest energy companies in Canada will collaborate to develop technology solutions to reduce their CO2 emissions. Three classes of solid sorbents will be developed by combining experimentation and molecular simulations while addressing process intensification and scale-up challenges. Thus far, no comprehensive study on the development of CO2 adsorption processes from cogeneration flue gas has considered the effects of impurities, scale-up, and process optimization. This research will generate fundamental knowledge from synthesizing novel materials and bench-scale studies to utilize the best sorbents for a long-term, pilot-scale unit. The innovative technologies developed from this study will be readily transferable for commercialization, thereby facilitating environmentally friendly energy production. The study's outcome contributes to the decarbonization of the energy sector and is well-aligned with Canada's vision of net-zero emissions by 2050. The creation of transformative know-how will make the CO2 capture process economically feasible. The research will help train 18 highly qualified personnel (HQP), including 3 PDFs, 4 PhDs, 3 MScs, and 8 Undergraduates, with expertise in GHG control technologies in Canada's natural resource and energy sectors.
