“…Efforts are increasing worldwide to significantly decrease GHG emissions as of 2050 in compliance with the Paris Agreement on Climate Change, which requires transformational measures (Sundaramoorthy et al 2023 ; UNFCCC 2023 ). Specifically, regarding global warming, the importance of substantial GHG emission mitigation for decades to come has been highlighted, namely, to reach or approach near-zero levels by the close of the century, ensuring a temperature increase less than 2 °C relative to pre-industrial levels, particularly in an effort to constrain it to 1.5 °C by 2050 (Bompard et al 2018 ; Hou et al 2023 ; IPCC 2023 ; Rockström et al 2017 ; Steffen et al 2015 ; Succar et al 2023 ). From 2017, the global mean temperature rise amounted to almost 1 °C and is estimated to reach the 1.5-°C indication as of 2040 in the case of these trends.…”

Solvent-based CO2 capture is a commonly employed post-combustion technique in processes involving absorber-stripper columns. This study focused on computer simulations with equilibrium- and rate-based modeling of CO2 capture using the amine solvents 2-amino-2-methyl-1-propanol (AMP), diethanolamine (DEA), and methyl diethanolamine (MDEA) and thermodynamic methods involving electrolyte NRTL models. The objective of this study was to understand the impacts of rate-based modeling, the type of amine, and thermodynamic methods on carbon capture. Within this study, the amine-based CO2 capture process from coal-power plant flue gas was studied using Aspen Plus modeling. Simulations were also conducted to determine the impact of thermodynamics and kinetics on the CO2 capture performance of the system. The results were analyzed on the basis of captured CO2 according to the solvents and models. The equilibrium approach was mostly invalid because of the oversimplified ideal stage assumptions through the column. The lowest carbon capture capacity was obtained with MDEA, while DEA yielded the best results. A sensitivity analysis with rate-based modeling showed the significant impact of the inlet CO2 composition. The amine-based CO2 capture process simulation included solution chemistry, electrolyte thermodynamics, rigorous transport property modeling, reaction kinetics, and rate-based multistage simulation, which could be applicable to different solvent systems.
