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. This method can be used because different hydrocarbons have different boiling points. WebEvery vaporization-condensation event (called a "theoretical plate") is similar to a simple distillation, and each event enriches the distillate in the lower boiling component. 2.5.6 describe and explain the separation of crude oil by fractional distillation; 2.5.7 describe the fractions as largely a mixture of compounds of formula CH, which are members of the alkane homologous series, and recall the names and uses of the following fractions: refinery gases used for bottled gases; petrol used as a fuel Normally, the vapour composition of any liquid mixture does not remain equal to the liquid composition. WebThe process of distillation exploits the difference in the boiling points of the components in the liquid mixture by forcing one of them into a gaseous state. Fractional Distillation. Fractional Distillation Fractional distillation is the process of taking a chemical mixture and using heat to separate out the various components in that mixture. WebPrinciple of Fractional Distillation. WebFractional distillation is used in oil refineries (Figure 5.41) to separate the complex mixture into fractions that contain similar boiling points and therefore similar molecular weights and properties. Distillation The more volatile component remains in a vapour state longer than the liquid component.

Fractional distillation Fractional Distillation WebPrinciple of Fractional Distillation. WebFractional distillation is the separation of a mixture into its component parts, or fractions. Normally, the vapour composition of any liquid mixture does not remain equal to the liquid composition. WebA method called fractional distillation, or differential distillation, has been developed for certain applications, such as petroleum refining, because simple distillation is not efficient for separating liquids whose boiling points lie close to one another. This page explains how the fractional distillation (both in the lab and industrially) of an ideal mixture of liquids relates to their phase diagram. This method can be used because different hydrocarbons have different boiling points. WebFractional distillation is used to separate crude oil into simpler, more useful mixtures. It uses distillation to fractionate. In fractional distillation, a mixture is heated so vapor rises and enters the fractionating column.
