Fractions of crude petroleum can be obtained by using _.
Correct answer: B. Fractional distillation
- A. Destructive distillation
- B. Fractional distillation
- C. Vacuum distillation
- D. Distillation
Explanation
Crude oil is separated by fractional distillation. Crude oil is heated to vaporize the different hydrocarbons in a tank that is cool at the top and hot at the bottom. The vapors then rise, and the different hydrocarbons condense at their specific boiling points, allowing them to be separated.
