Electrically-driven separation systems and methods for use in oil recovery.

Electrochemical desalination for oil recovery

Disclosed are methods to predict the occurrence of polarization and the design and operation of electrochemical systems to maintain a current density below the limiting current density and avoid instability.

Methods and systems for polarization control

Systems and methods for the desalination of seawater or brackish water for the purpose of obtaining potable water. Systems may include a combination of electrodialysis and electrodeionization modules. The system configuration and process controls may achieve low energy consumption and stable operation.

Electrodesalination system and method

Electrochemical separation devices are configured for lower energy consumption. Techniques for reducing shadow effect may involve providing distance between a spacer screen and an adjacent ion-selective membrane. A spacer having a screen that is thin relative to a surrounding frame may be used. Mild pressure may also be applied to a compartment to promote distance between a spacer screen and an adjacent ion-selective membrane.
