the process of fractional distillation of petroleum
The petrol crude is a mixture of many different types of hydrocarbons mixed together. The process of fractional distillation is used to separate these different ingredients of petroleum crude during the manufacture of petrol and other fuels derived from petroleum crude.he refining is done by separating all the different fuels and chemicals by fractional distillation in an oil refinery. Fractional distillation involves heating the crude petroleum, so that at different temperatures the different fuels and chemicals will vaporise and be collected in a pure state.
