Which of the following methods is used for the separation of different components of petroleum?
Which of the following methods is used for the separation of different components of petroleum?
The correct option is C Fractional distillation
The explanation for the correct option:
Different separation techniques are present depending upon the property of the substance to be separated.
(C) Fractional distillation: It is used to separate the components present in petroleum, where the components separate according to the boiling point.
The component which is having lowest boiling point distils over first followed by the next and so on.
The explanation for the incorrect option:
(A) Sublimation: It is a technique which involves the direct conversion of a substance from a solid state to the gaseous state.
The mixture of sublimable and non sublimable substances can be separated using sublimation, where the sublimable substance undergoes state change from a solid state to a gaseous state.
(B) Simple distillation: It is used to separate the miscible liquids having a boiling point difference greather than .
(D) Chromatography: It is used to separate the components present in a substance depending upon the solubility of components in the solvent. When the solvent moves through the stationary phase, components separate into different heights depending on the solubility.
Thus, option (C) i.e.., Fractional distillation is correct, where the components of petroleum are separated using it.
