4:08 describe how the industrial process of fractional distillation separates crude oil into fractions

  • Crude oil is separated by fractional distillation.
  • Crude oil is heated and the oil evaporates.
  • The gas goes into the fractional distillation tower. As the gas rises the temperature falls.
  • Fractions with higher boiling points condense and are collected nearer the bottom of the tower.
