本研究は、450MWのNGCC発電所を対象に、アミン吸収法、膜分離法、ハイブリッドシステムを排ガス再循環（EGR）と組み合わせたCO2回収構成の技術経済評価を実施した。選択的EGRとアミン吸収の統合が最も優れ、エネルギー損失を単独吸収より30%以上削減し、LCOE約72 USD/MWh、CO2回避コスト約39 USD/tCO2を達成した。CCSUの実現可能性向上に寄与する。
English
This study conducts a techno-economic assessment of CO2 capture configurations (amine absorption, membrane, hybrid) integrated with exhaust gas recirculation (EGR) for a 450 MW NGCC plant. Selective EGR with amine absorption achieves the best performance, reducing energy penalty by over 30% compared to standalone absorption, with LCOE of ~72 USD/MWh and CO2 avoidance cost of ~39 USD/tCO2, highlighting a promising strategy for CCSU feasibility.

📄 Abstract（原文）
Post-combustion amine absorption is the most mature CO2 capture technology, while membrane separation is a promising alternative due to its modularity and operational simplicity. Process intensification through exhaust gas recirculation (EGR) has also gained attention for increasing flue gas CO2 concentration and reducing capture energy demand. However, comprehensive techno-economic comparisons of absorption, membrane, and hybrid systems under EGR-integrated NGCC conditions remain limited. This study presents a techno-economic assessment of multiple CO2 capture configurations for a 450 MW NGCC power plant. Process simulations were performed using Aspen Plus and Aspen Custom Modeler to evaluate absorption, membrane, and hybrid systems integrated with conventional and selective EGR. The analysis considers full steam cycle integration and compares energy consumption, net plant efficiency, levelized cost of electricity (LCOE), and CO2 avoidance cost. The results show that EGR significantly improves carbon capture performance. Among all cases, selective EGR combined with amine absorption delivers the best performance, reducing the energy penalty by more than 30% compared with standalone absorption and by over 70% relative to membrane separation. This configuration achieves an LCOE of approximately 72 USD/MWh and a CO2 avoidance cost of about 39 USD/tCO2, outperforming the selective EGR–membrane system (77 USD/MWh and 51 USD/tCO2). These findings demonstrate that integrating selective EGR with amine absorption is a highly promising strategy for improving the technical and economic feasibility of CCSU in NGCC power plants.
