本研究は、新規のAMP–DA2MP–MEA三溶媒アミン混合液のCO2吸収性能を実験的に評価した。ベンチスケールの吸収塔を用いて、初期吸収効率、物質移動係数、吸収熱、密度、粘度を測定し、従来のMEA溶液と比較した。その結果、混合液は吸収塔高さを41～58%削減でき、物質移動係数も65.9～118.9%向上した。吸収熱は最大28.8%高いが、CO2回収の高性能化が期待される。
English
This study experimentally evaluated the CO2 absorption performance of a novel AMP–DA2MP–MEA tri-solvent amine blend. Using a bench-scale absorption column, initial absorption efficiency, mass transfer coefficient, absorption heat, density, and viscosity were measured and compared with conventional MEA. The blend reduced absorber height by 41–58% and increased mass transfer coefficient by 65.9–118.9%. Although absorption heat was up to 28.8% higher, the blend shows promise for advanced CO2 capture.

📄 Abstract（原文）
This study investigated the initial CO2 absorption efficiency, initial average overall absorption mass transfer coefficient, absorption heat, heat of vaporization, density, and viscosity of the novel aqueous AMP–1,5-diamino-2-methylpentane (DA2MP)–MEA tri-solvent amine blend solution using a bench-scale absorption column process plant. The concentration of AMP was kept constant at 2 mol·L−1, while the DA2MP concentration ranged from 1 to 2 mol·L−1 and MEA concentration from 2 to 3 mol·L−1, while the total tri-solvent amine blend concentration was kept at 6 mol·L−1. Results showed that the AMP–DA2MP–MEA blend possessed some of the lowest densities but higher viscosities than the other studied amine systems. Results revealed that the AMP–DA2MP–MEA blend has a lower absorber column height (18% to 58%) to achieve initial 90% CO2 absorption efficiency compared to other investigated amine solutions. Notably, the AMP–DA2MP–MEA blends achieved the greatest reduction in absorber height (41–58%) relative to the benchmark MEA solution. The AMP–DA2MP–MEA blend also possesses a higher initial absorber mass transfer coefficient compared with the benchmark MEA solution (65.9% to 118.9%), the AMP–DA2MP blend (6.6% to 40.6%), and the AMP–PZ–MEA blend (44.8% to 91%). The AMP–DA2MP–MEA blend has higher heat of vaporization (up to 9.8%) and absorption heat (up to 28.8%) compared with the other amine systems. These findings indicate that the AMP–DA2MP–MEA tri-solvent blend is a strong candidate for advanced CO2 capture applications and requires further investigation.
