In post-combustion CO_2 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

CO_2 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.
