AI Technical Summary
During electrodialysis, the diffusion loss of organic amine compounds caused by the concentration difference of the solution on both sides of the membrane results in the inability to effectively recover the organic amine compounds, affecting their reuse and causing equipment corrosion.
A combined system of four-compartment and two-compartment electrochemical reactive membrane stacks is adopted. Through specific compartment arrangement and membrane type, the concentration gradient diffusion of organic amine compounds is restricted, and the recovery rate of organic amine compounds is improved through neutralization reaction and purification process.
It effectively reduces the loss of organic amine compounds, improves the recovery rate of organic amine compounds, extends the life of ion exchange membranes, and reduces the risk of equipment corrosion.
