TIC Measurement Method for CO2 in Amine Solutions

This application note presents a technical report on the TIC (Total Inorganic Carbon) measurement method using the multi N/C 2300 analyzer for monitoring CO2 concentrations in amine scrubbing solutions. The report outlines the necessity for accurate CO2 absorption monitoring in aqueous amine solutions, which are critical for reducing CO2 emissions from fossil fuel combustion. It details the methodology employed for TIC determination, including sample preparation, measurement processes, and calibration standards. The document compares TIC analysis with traditional titration methods, highlighting the advantages of TIC in terms of accuracy and reduced manual effort. Results demonstrate that the TIC method achieves low standard deviations and high reproducibility, making it suitable for routine monitoring in carbon capture applications. The report concludes with acknowledgments of contributions from Sulzer Chemtech AG and emphasizes the operational benefits of using the multi N/C analyzers for CO2 monitoring in industrial applications.
