What is the removal rate at each stage of electrodialysis?
It’s hard to say. Crude oil electrodialysis is influenced by multiple factors: 1. The density difference between oil and water; 2. Temperature; 3. The quality and quantity of water used for desalination; 4. The degree of mixing of the oil-water feed mixture; 5. The residence time in the desalination tank; 6. The strength of the electric field used for desalination; 7. The type of demulsifier and its effectiveness; 8. The composition of salts in the crude oil; 9. The viscosity of the crude oil at the desalination temperature. It is recommended that the person in question conduct simulation tests for crude oil desalination and screen different demulsifiers, while also optimizing the process – as there is no fixed solution to such problems.
Level 3: 90%-95%, Level 2: 70%-85%, Level 1: 60%-75%
