Crude Oil Fractions & Their Uses

The video explains how fractional distillation separates hydrocarbons into fractions based on boiling points. It covers the uses of various fractions like refinery gas, petrol, naphtha, kerosene, diesel, and residue fractions such as fuel oil and bitumen. The importance of crude oil in everyday life, including its role in fueling vehicles, flights, and producing plastics, is highlighted.
