Research Triangle Institute (RTI) is developing and testing, at large pilot scale, a non-aqueous solvent (NAS; i.e., water-lean solvent) carbon dioxide (CO2) capture process to confirm the potential to reduce the parasitic energy penalty associated with the capture of CO2 from flue gas; demonstrate the long-term process operational reliability at static and dynamic conditions; and verify the solvent degradation rate, emissions, solvent loss, and corrosion characteristics of the solvent at engineering scale.
