本研究では、AMP、PZ、DETAからなる三元混合アミン溶媒のCO2吸収・再生性能を実験的に評価した。結果、従来のMEAと比較して、平衡CO2負荷量33～61%向上、再生エネルギー53～58%削減を達成。さらに、AMP-DETA二元系よりも再生エネルギーが26～30%低く、組成調整による柔軟な運転が可能であることを示した。
English
This study experimentally evaluates a tri-solvent amine blend (AMP-PZ-DETA) for post-combustion CO2 capture. Compared to benchmark MEA, it achieves 33-61% higher equilibrium CO2 loading and 54-58% lower regeneration energy. The system also shows 26-30% lower energy than AMP-DETA blend, with operational flexibility through composition adjustment.

📄 Abstract（原文）
This study evaluates the equilibrium CO 2 loading, CO 2 absorption capacity, cyclic capacity, initial CO₂ desorption rate, heat of absorption, heat of vaporization, and overall regeneration energy of a tri-solvent amine blend system comprising 2-amino-2-methyl-1-propanol (AMP), piperazine (PZ), and diethylenetriamine (DETA). The AMP concentration was fixed at 2 mol/L, while PZ and DETA concentrations each were varied between 0.5 and 1.5 mol/L, maintaining a total amine concentration of 4 mol/L (37–40 wt%). Experimental results demonstrate that the AMP–PZ–DETA tri-solvent blend system exhibits significantly higher equilibrium CO 2 loading (33.3–60.8%), CO 2 absorption capacity (3.8–26.9%), cyclic capacity (18.5–66.2%), initial CO₂ desorption rates (117–137%), while reducing regeneration energy by 53.8–57.8% relative to the benchmark monoethanolamine (MEA) solution, and lower regeneration energy (26.2–30.1%,) than the AMP–DETA bi-solvent blend. Furthermore, both the heat of absorption and heat of vaporization for the tri-solvent system were found to be lower than those of the AMP–DETA blend and MEA. The AMP–PZ–DETA tri-solvent blends also exhibited relative regeneration energy comparable to, and in several cases lower than, that of the optimal concentrations reported for recently investigated tri-solvent amine blend systems. Overall, the results indicate that the AMP–PZ–DETA system offers improved CO 2 absorption and regeneration characteristics, while the variation in tri-solvent blend composition highlights its operational flexibility in maintaining low energy requirements without compromising the CO 2 absorption and cyclic capacities for post-combustion CO₂ capture applications.
