Fractional Distillation

The video explains how fractional distillation separates crude oil into useful fractions. Crude oil, a mixture of hydrocarbons, is heated and vaporized. The vapor enters a fractionating column with a heat gradient, where different hydrocarbons condense at various levels based on their boiling points. Short-chain hydrocarbons with lower boiling points condense at the top, while long-chain hydrocarbons with higher boiling points condense at the bottom. The separated fractions have various uses, such as fuels and raw materials for chemicals and plastics.
