Detailed explanation-1: -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.
Detailed explanation-2: -Fractional distillation is used to separate crude oil into simpler, more useful fractions. A fraction of crude oil is a group of hydrocarbon molecules of similar size with similar boiling points . Their similar boiling points mean that they can be separated by fractional distillation.
Detailed explanation-3: -In a fractional distillation, a mixture of liquids is boiled and the resulting vapors travel up a glass tube called a “fractionating column” and separate. The fractionating column is placed between the flask containing the mixture and the “Y” adaptor and improves the separation between the liquids being distilled.
