📄 Abstract（原文）
Post-combustion carbon capture remains an essential option for reducing industrial greenhouse gas emissions; however, conventional solvent systems continue to face limitations related to operational stability and environmental sustainability. This study examines sodium carboxymethyl starch (Na-CMS), a water-soluble polymeric solvent, as a non-reactive platform for CO2 capture and process optimization. Despite growing interest in polymer-based absorbents, their performance in absorber-stripper configurations under realistic operating conditions remains insufficiently understood. To address this gap, a steady-state absorber-regeneration configuration was developed in Aspen Plus to evaluate CO2 absorption using Na-CMS in a tray column system. Key process and economic parameters were evaluated through a scenario-based techno-economic framework, with system performance assessed using Net Present Value (NPV), Levelized Cost of Carbon Capture (LCOCC), Return on Investment (ROI), and Payback Period (PBP). Three representative cases were analyzed to identify economic thresholds and feasibility limits. An overall CO2 capture efficiency of 98% was attained with Na-CMS. The optimized operating region was identified at an absorber temperature of 30 °C, a moderate operating pressure of 10 bars, and a solvent circulation rate of 26 kmol.h-1. Under these conditions, simulated CO2 removal exceeded typical polymeric-solvent efficiency and delivered predictable trade-offs between capture fraction and energy penalty. Sensitivity analysis showed that energy duty, capture rate, and carbon price most strongly influence project economics. Na-CMS emerges as a tunable platform for further materials and process refinement; experimental validation and targeted material modification are recommended to reduce regeneration duty and improve commercial prospects.
