本論文は、アミン系溶媒を用いたCCSを米国の石炭・天然ガス火力発電所に導入した場合の大気汚染とCO2排出への影響を評価。石炭火力では排ガス前処理による健康便益が大きい一方、天然ガス火力ではアンモニア対策なしにMEA溶媒を用いると健康被害が4倍に増加する可能性を示した。
English
This paper evaluates air pollution and CO2 emission impacts of amine-based CCS retrofits at US coal and NGCC plants. Health benefits are substantial for coal plants with flue gas pretreatment, but using monoethanolamine without NH3 controls at NGCC plants could increase health burdens fourfold, underscoring the importance of solvent choice and emission controls.

📄 Abstract（原文）
Abstract Postcombustion carbon capture and storage (CCS) can reduce CO 2 emissions from coal and natural gas combined cycle (NGCC) power plants. Integrating CCS affects other air pollutant emissions as well. Flue gas must be pretreated to avoid undesirable reactions between pollutants and solvents, whereas amine-based solvents can degrade, leading to NH 3 emissions. Here we explore the air pollution and CO 2 emissions impacts of national-scale postcombustion CCS adoption at coal and NGCC plants using monoethanolamine and a mixture of 2-amino-2-methyl-1 propanol and piperazine (CESAR1) as representative solvents. If CCS retrofits are only viable on newer facilities, 97% of NGCC plant emissions are addressable versus 27% of coal plant emissions. Potential human health benefits of CCS retrofits are concentrated at coal plants, where the net benefits of added flue gas pretreatment are substantial, regardless of solvent. NGCC plants, however, require NH 3 emissions controls and/or modern solvents, as using monoethanolamine without NH 3 emissions controls could increase net human health burdens fourfold. Thus, the human health impacts from adopting postcombustion CCS using amine-based solvents depend on solvent choice, fuel type, existing flue gas concentration and NH 3 emission controls. Careful consideration of such factors can maximize the climate and health benefits of postcombustion CCS deployment.
