What is a refinery?

A refinery is an industrial facility where raw materials—most commonly crude oil—are processed and transformed into useful products like gasoline, diesel, jet fuel, and other petrochemicals. The refining process involves separating, purifying, and converting the raw materials through various physical and chemical methods. Refineries play a crucial role in the global energy supply chain, ensuring that crude oil and other feedstocks are converted into market-ready fuels and products. Workers in refineries typically specialize in areas like operations, maintenance, safety, and quality control to ensure efficient and safe production.
