to separate crude oil into more useful things like petrol, LPG, naphtha etc
Fractional distillation is used to separe the components of a liquid.
Distillation is used frequently.
The key difference between fractional and simple distillation is that fractional distillation is used when the components in the mixture have closer boiling points, while simple distillation is used when the components in the mixture have a large difference in their boiling points
Distillation is used to extract ethanol.
Whether it is better to use fractional or simple distillation depends on the liquids being separated and on the boiling points of the liquids. When there is a great difference between the boiling points of the liquids, simple distillation may be a better option. Likewise, if there is a small difference in boiling points, then fractional distillation is used.
fractional distillation
Fractional distillation is used to obtain diesel fuel, kerosene, gasoline and many others useful products.
Electrolysis is a process, fractional distillation another.
After fractional distillation petrol is not a mixture.
fractional distillation is usually use to separate the constituents of crude oil, into petroleum, jet fuel, asphalt, kerosene, and others. Most oil based products are separated by fractional distillation.
Fractional Distillation from petroleum
Simple distillation is used to separate liquids with significantly different boiling points, while fractional distillation is used for liquids with closer boiling points. Vacuum distillation is used at lower pressures to lower the boiling points of substances.
