本研究では、モノエタノールアミン（MEA）を用いた燃焼後炭素回収プロセスに対して、不確実性を考慮したロバスト最適化手法（PyROS）を適用。90%から99%以上のCO2回収率を達成し、最大98%までの回収率で、名目上の最適解と比較してわずかなコスト増加でリスク回避的な設計が可能であることを示した。これにより、過剰設計による不必要なコスト負担を回避できる。
English
This work applies robust optimization (PyROS) to design a monoethanolamine-based post-combustion carbon capture process under uncertainty. It achieves risk-averse designs for CO2 capture rates from 90% to over 99%, with solutions up to 98% only marginally more expensive than nominal optimal. The results demonstrate that robust optimization can avoid unnecessary cost burdens from ad hoc overdesign.

📄 Abstract（原文）
High Resolution Image Download MS PowerPoint Slide The development and widespread commercial deployment of carbon capture and storage technologies will be instrumental in expanding affordable energy production and increasing the availability of CO 2 as a feedstock for several industrial applications. This development can be accelerated by applying computational model-based process optimization methodologies that explicitly account for the impact of parametric uncertainties to obtain solutions that exhibit minimal technical risk. Robust optimization (RO) is one such prominent methodology. In this work, we present a successful application of the nonlinear two-stage RO solver PyROS to a detailed rate-based, equation-oriented model for the economical design and operation of a monoethanolamine scrubbing process for postcombustion carbon capture under uncertainty in the thermodynamic property submodel parameters. Our application enables us to successfully obtain risk-averse model solutions for CO 2 capture targets ranging from 90% to over 99%, with solutions for capture targets of up to 98% only marginally more expensive than their nominally optimal counterparts. Thus, our results demonstrate that employing RO and the PyROS solver can help us obtain risk-averse carbon capture process designs without inherently unnecessary cost burdens that are often associated with ad hoc overdesign approaches.
