Components of crude petroleum can be separated by :
Components of crude petroleum can be separated by :
Open in App
Solution
The correct option is C fractional distillation
Correct answer (d) fractional distillation
- Fractional distillation: separation of a mixture into its parts where components have very small difference in boiling points.
- Crude petroleum is a mixture of many different components that have varied boiling points between the range of 25℃ or more.
Explanation for incorrect options :
- Distillation is used to separate components of a solution having a larger difference in their boiling points.
- In evaporation only the solid component of the mixture is obtained while the liquid component escapes in vapour form.
- Filtration is used to separate when the impurities are insoluble in nature and in crude oil all components are soluble in nature.
