The University of Texas at Austin is developing technologies to safeguard amine-based carbon dioxide (CO2) capture processes from solvent loss by oxidation. The project team is evaluating strategies to minimize amine oxidation in advanced second- and third-generation solvents caused by two of the most significant impurities: oxygen and nitrogen dioxide (NO2). These effective technologies will reduce the cost and environmental risk of solvent-based carbon capture systems by addressing the effects of flue gas impurities on solvent loss and will make significant progress toward achieving $30/tonne of CO2 captured by 2030.
