hydrocarbons
Most of the compounds in crude oil are hydrocarbons. This means that they only contain hydrogen and carbon atoms, joined together by chemical bonds. There are different types of hydrocarbon, but most of the ones in crude oil are alkanes

Boiling point and state at room temperature
Hydrocarbons have different boiling points, and can be either solid, liquid or gas at room temperature: Small hydrocarbons with only a few carbon atoms have low boiling points and are gases. Hydrocarbons with between five and 12 carbon atoms are usua

The alkanes are a family of hydrocarbons that share the same general formula. This is: CnH2n+2 The general formula means that the number of hydrogen atoms in an alkane is double the number of carbon atoms, plus two. For example, methane is CH4 and et

Distillation
Distillation is a process that can be used to separate a pure liquid from a mixture of liquids. It works when the liquids have different boiling points. Distillation is commonly used to separate ethanol (the alcohol in alcoholic drinks) from water.Th

Fractional distillation
Fractional distillation differs from distillation only in that it separates a mixture into a number of different parts, called fractions. A tall column is fitted above the mixture, with several condensers coming off at different heights. The column i
