Performance of Amine-based Post-combustion CO2 Capture:Comparison of MEA and EDA

This study investigates the CO₂ capture performance of various amine-based solvents, focusing on ethylenediamine (EDA) as a potential alternative to the widely used monoethanolamine (MEA) in post-combustion CO₂ capture. Experiments were conducted to evaluate CO₂ capture capacities and removal efficiencies under different conditions, including solvent concentrations and feed flow rates, in both batch and continuous absorption-regeneration processes. The results show that EDA demonstrates significantly higher CO₂ capture capacity and removal efficiency compared to MEA, with reduced energy consumption due to lower regeneration temperature. These findings suggest that EDA is a promising candidate for improving the efficiency and cost-effectiveness of CO₂ capture in carbon capture and storage (CCS) technology.
