In carbon capture systems, solvents like CESAR1 absorb CO\u2082 from industrial exhaust before it reaches the atmosphere. But over time, exposure to heat, oxygen, and other gases or contaminants<\/strong> can cause the solvent to degrade \u2014 producing unwanted by-products, reducing performance, and potentially creating environmental risks.<\/p>\n

To ensure carbon capture is not only effective but also safe and sustainable, we need to understand:<\/p>\n

    \n
  • Which degradation products form.<\/strong><\/li>\n
  • How quickly the solvent breaks down.<\/strong><\/li>\n
  • How to manage these changes in real-world industrial conditions.<\/strong><\/li>\n<\/ul>\n

    This study is a crucial step in answering those questions.<\/p>\n

    The team exposed CESAR1 to two types of stress conditions:<\/span>\u00a0<\/span><\/p>\n

      \n
    1. Oxidative degradation<\/span><\/b> \u2013 simulating exposure to oxygen <\/span>in the<\/span> flue gas<\/span>\u00a0<\/span><\/li>\n
    2. Thermal degradation<\/span><\/b> \u2013 simulating high-temperature environments <\/span>encountered during<\/span> solvent regeneration or reclaiming<\/span> <\/span><\/li>\n<\/ol>\n

      They used advanced chemical analysis to identify and quantify what compounds formed under each condition.\u00a0<\/span><\/p>\n

        \n
      • A total of 48 degradation compounds<\/strong> were identified and measured in CESAR1.<\/li>\n
      • 15 of these compounds had not been previously reported<\/strong> in CESAR1 research.<\/li>\n
      • The solvent degraded faster as a blend<\/strong> than its two components (AMP and PZ) do individually \u2014 meaning chemical interactions in the blend accelerate breakdown.<\/li>\n
      • Harmful by-products such as nitrosamines and nitramines<\/strong> were found to form even in the absence of nitrogen oxides (NOx).<\/li>\n
      • Volatile compounds<\/strong> like ammonia, formaldehyde, and acetaldehyde were also detected \u2014 these can escape into the air or contaminate the captured CO\u2082 if not properly controlled.<\/li>\n
      • The study confirmed that the most abundant nitrogen-containing degradation products<\/strong> in CESAR1 have now been identified.<\/li>\n<\/ul>\n

        This research directly supports the goals of the AURORA project by helping to:<\/p>\n

          \n
        • Develop more targeted and efficient monitoring and control strategies<\/strong> for CO\u2082 capture plants.<\/li>\n
        • Improve solvent maintenance plans<\/strong>, such as when and how to reclaim the solvent.<\/li>\n
        • Guide environmental safety protocols<\/strong> to manage emissions and waste.<\/li>\n
        • Ensure CO\u2082 product quality<\/strong>, especially when reuse or storage is planned.<\/li>\n<\/ul>\n

          Understanding solvent degradation is essential to making CESAR1 \u2014 and carbon capture more broadly \u2014 safe, cost-effective, and ready for full-scale deployment<\/strong>.<\/p>\n

            This study provides essential knowledge about how the CESAR1 solvent degrades under realistic CO\u2082 capture conditions. By identifying key degradation products and their formation pathways, the research lays the groundwork for improved solvent monitoring, safer operation, and more efficient long-term use of CESAR1 in industrial settings. These insights bring the AURORA project one step closer to enabling the large-scale deployment of carbon capture technologies across Europe.<\/p>\n
