Crude oil is extracted from underground reservoirs and transported via pipeline, tanker, or rail to a refining facility. Heated crude oil is introduced into a tall fractionating column, where it vaporizes and rises through trays or packing.

Fluid Catalytic Cracking (FCC) uses a hot, powdered catalyst to vaporize heavy feedstocks in a reactor, producing a high-octane gasoline blendstock and olefins for plastics. Light, sweet crude commands a premium because it contains fewer impurities, whereas heavy, sour crude requires more intensive processing to remove sulfur and other contaminants.
The result is distinct streams: overhead gases, naphtha, kerosene, diesel, and vacuum gas oil. Cracking processes break long-chain molecules into shorter, more valuable hydrocarbons.

Without refining, the energy and petrochemical sectors that power global economies would grind to a halt, making it a cornerstone of industrial civilization. The quality of the feedstock varies dramatically depending on its geological origin.
