摘要

燃烧后CO_2捕集过程中，有机胺吸收剂易降解生成中性降解产物及热稳定盐（heatstable salt

HSS）。电渗析（electrodialysis

ED）技术作为一种常温常压下高效脱除HSS的方法，在胺回收领域具有广阔的应用前景。系统综述了电渗析用于有机胺回收的研究进展，包括不同电渗析装置的构型特点、关键工艺参数（电压、电流密度、初始HSS浓度、CO_2负荷等）对脱除效率、胺损失与能耗的影响机制。重点总结了多段膜堆、电渗析与树脂或双极膜耦合等工艺优化策略，并对不同应用场景下电渗析装置的工业运行性能进行了比较分析。最后，针对膜材料稳定性、能耗与成本控制等挑战，提出了未来电渗析在CO_2捕集胺回收领域的发展方向。

Abstract

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.
