Reclaiming of degraded MEA solutions by electrodialysis: Results of ED pilot campaign at post-combustion CO2 capture pilot plant

- Reclaiming of degraded MEA solvent with electrodialysis was studied on the pilot level.
- ED reclaiming provides quite uniform removal of HSS anions from loaded lean MEA.
- Long-term stability of ion-exchange membranes in the presence of amine-based solvents was shown.
