Advances in electrodialysis technologies for amine reclaiming in post-combustion carbon dioxide capture
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
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.
