Different materials boil at different temperatures (generally and very roughly speaking, for similar molecules the lighter they are the lower the temperature at which they boil). By raising the temperature enough to boil the lighter components of a mixture but not enough to boil the heavier ones, the mixture can be separated into two "fractions", one of which is rich in lighter molecules and one which is rich in the heavier molecules.
In practice, this is generally done in "fractionating columns", where the temperature gradually decreases as you go up the column. The very lightest molecules will make it all the way to the top; slightly heavier ones will condense back into liquid a little further down, and so on. By taking out the liquid at different heights, you can separate the crude oil into many different fractions with different properties (petroleum ether, gasoline, kerosene, paraffins, etc.).
Because the boiling points are different.
The boiling points of crude oil are very different.
fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points.
Typically they are separated in a fractional distillation tower.
The separation is possible by distillation.
Fractional distillation.
The various hydrocarbons present in petroleum have different boiling points. as the number of carbon atoms in a hydrogen increases,it's boiling point also increases.This property is used to separate the different components of petroleum by fractional distillation.The components with different boiling points are known as fractions, and the process of separating the fractions by fractional distillation is known as refining.

fractional distillation
Because they evaporate at different rates, each has a different boiling point.
Typically they are separated in a fractional distillation tower.
The main differences in distillation columns fractions are the separation of a mixture. It is component parts or factions that separate chemical compounds.
both of these are liquid hydrocarbons so have the same chemical properties therefore can not beseparated by chemical means by physical means their separation is not possible by filtration because both are miscible so only method to separate them is fractional distillation because they have different boiling points.
First of all you have to bend down and suck it :). I Hope It Helped. TROLL.
