Which process is used to separate crude oil into different fractions based on boiling points?
Correct answer: C. Fractional distillation
- A. Cracking
- B. Reforming
- C. Fractional distillation
- D. Polymerization
Explanation
Fractional distillation is the primary process in oil refineries. It separates crude oil into useful fractions like gasoline and diesel by heating it and allowing components to vaporize and condense at different temperatures in a tall fractionating column.
