中国の石炭火力に併設された産業用CCS施設で、MEA単独系とAMP等混合溶剤系のアミン排出をリアルタイム測定した。総アミン排出は2.3〜30.4ppmで、単独系はNH3やアルデヒド等の分解物が多く、混合系はAMPが支配的で時間変動が大きい。排出挙動は実験室・パイロット規模と異なり、運転条件に依存するスケール特有のメカニズムを示す。大規模CCS展開下の排出監視・管理に示唆を与える。
English
Real-time measurements at an industrial coal-fired amine-based carbon capture facility in China compared a single-MEA system with a blended-solvent (AMP/DGA/MDEA) system. Total amine emissions ranged 2.3–30.4 ppm; the single-MEA system emitted more degradation products (NH3, C1–3 aldehydes), while the blended system was dominated by AMP with strong temporal variability. Emission behavior differed from lab and pilot studies, revealing scale-dependent mechanisms and informing monitoring under large-scale CCS deployment.

日本のGX文脈において
日本でもJERAや大手電力がアミン吸収法CCSの実証を進めており、実機スケールでのアミン排出特性は環境影響評価・地域合意形成の論点となる。GX推進におけるCCS社会実装の環境モニタリング設計に示唆を与える。
In the global GX context
As CCUS scales under net-zero pathways and transition finance, real-world emissions data from industrial capture facilities are essential for environmental safeguards and MRV frameworks. This study fills a gap between lab/pilot data and industrial-scale amine slip, relevant to CCS deployment standards and permitting debates globally.

📄 Abstract（原文）
Abstract Postcombustion carbon capture using amine-based solvents is a key technology for CO2 mitigation from flue gas. However, amine slip during operation may lead to the emissions of solvents and their products into the atmosphere, raising environmental and health concerns. Despite increasing deployment of large-scale facilities, emission characteristics under real industrial conditions remain scarce. This study conducted real-time measurements of the flue gas at an industrial coal-fired carbon capture facility in China, covering both a single monoethanolamine (MEA) system and a blended-solvent system containing 2-amino-2-methyl-1-propanol (AMP), diglycolamine, and N-methyldiethanolamine. Total amine emissions, representing gas-phase amines together with the aerosol-associated fraction that volatilized during heated sampling, ranged from 2.3 to 30.4 ppm. The single-MEA system produced higher concentrations of degradation products including NH3, C1–3 aldehydes, and low-molecular-weight amines. In the blended system, strong temporal variability was dominated by AMP, while degradation products were partially decoupled from parent amines. Emission behaviors differ between the single-MEA and blended-solvent systems, with emissions decreasing in the single-MEA system with lean solvent temperature and inlet CO2 concentration, and increasing in the blended-solvent system with wash water temperature and CO2 loading. These characteristics differ from those reported in laboratory and pilot-scale systems, reflecting scale-dependent emission mechanisms governed by coupled operating conditions and providing insights into emission monitoring and management under future large-scale carbon capture deployment.
