Visbreaking__________________?
Correct answer: B. Produces fuel oil of lower viscosity
- A. Uses natural gas as feed
- B. Produces fuel oil of lower viscosity
- C. Is carried out at atmospheric pressure
- D. Produces gasoline only
Explanation
Visbreaking is a mild thermal cracking treatment of heavy petroleum fractions that reduces the viscosity of the resulting residual fuel oil. It does not use natural gas as feed, operate necessarily at atmospheric pressure, or produce gasoline only.
