Question

Which process is used to obtain petrol, kerosene and diesel from crude oil?

• A. Evaporation
• B. Crystallization
• C. Filtration
• D. Fractional distillation

Answer 1

The correct option is D

Fractional distillation

Fractional distillation is a process by which components in a chemical mixture are separated into different parts (called fractions) according to their different boiling points. Fractional distillation is used to purify chemicals and also to separate mixtures to obtain their components. The chemical and petroleum industry rely on fractional distillation. So, obtaining petrol, kerosene and diesel from crude oil can be done by this process.
