In post-combustion CO2 capture, organic amine absorbents are prone to degradation, forming heat-stable salts (HSS) that impair absorption performance and accelerate equipment corrosion. Electrodialysis (ED), operating under ambient conditions with high HSS removal efficiency, has emerged as a promising technology for amine recovery. This review systematically summarizes recent advances in ED for amine solvent recovery, covering the configurations of different ED systems and the mechanisms by which key process parameters (voltage, current density, initial HSS concentration, CO2 loading, etc.) affect removal efficiency, amine loss, and energy consumption. It highlights process optimization strategies such as multi-stage membrane stacks and ED coupling with resins or bipolar membranes, and compares industrial performance data across different applications. Finally, challenges related to membrane stability, energy consumption, and cost control are discussed, with perspectives on future development directions for ED-based amine recovery in carbon capture systems.
