Salt content (measured as sodium chloride) in electrically desalted crude oil comes down to a level of about __________________ ptb (pounds per thousand barrel) ?
Correct answer: B. 3
- A. 0.03
- B. 3
- C. 35
- D. 70
Explanation
Electrostatic desalting removes most brine and reduces residual salt in crude oil to roughly 3 pounds per thousand barrels. The values 35 and 70 ptb represent much higher, inadequately desalted levels.
