It is usually carried out to separate two volatile liquids having nearly same( not equal ) boiling points. The liquid with lower boiling point is collected as the condensate. The liquid with higher boiling point remains behind in the distillation flask. Carried out in petroleum industry to separate components of raw oil. Also used in separation of organic liquids.
Argon (and the other noble gases) is separated by fractional distillation of liquid air.
Fractional distillation is used to separe the components of a liquid.
Electrolysis is a process, fractional distillation another.
After fractional distillation petrol is not a mixture.
You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process
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.
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
Crude oil is separated into its components through a process called fractional distillation. In this process, crude oil is heated to high temperatures in a distillation tower, causing it to vaporize. The vapor is then cooled and condensed back into liquid form at different levels in the tower, allowing for the separation of components based on their boiling points.
Fractional distillation is applied when many components exist an the differences between boiling points are under 25 oC.
fractional distillation
Fractional distillation is a separation method based on the differences between boiling poins of components.
