Question

What is the use of fractional
column in the process of fractional distillation

Answer 1

A fractionating column or fractional column is an essential item used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on the differences in volatilities.

Explanation:

During the fractional distillation of crude oil:

• heated crude oil enters a tall fractionating column , which is hot at the bottom and gets cooler towards the top.

• vapours from the oil rise through the column.

• vapours condense when they become cool enough.

• liquids are led out of the column at different heights.

Answer 2

Explanation:

Fractional column is there to separate the components which are being produced during fractional distillation.
