During electrical desalting of crude oil, the electrical conductivity of a mixture of crude oil and water (which ranges between 3 to 8% water) ________________ with increase in the amount of water?
Correct answer: D. Increases
- A. Decreases
- B. Decreases linearly
- C. Remains unchanged
- D. Increases
Explanation
Water introduces dissolved ionic salts into the crude-water mixture and creates a more conductive continuous pathway, so conductivity rises as water content increases over this range. The crude oil itself is a poor electrical conductor.
