The purpose of a refinery is to separate and purify these different components. Most refinery products can be grouped into three classes: Light distillates (liquefied petroleum gas, naphtha, and gasoline), middle distillates (kerosene and diesel), and heavy distillates (fuel oil, lubricating oil, waxes, and tar).

Refiners process crude oil after extraction to separate it into usable components. The first step in distillation heats oil in a column until it evaporates at a specific temperature. As the vapor rises, it cools and condenses at various temperatures, dividing into fractions such as gasoline, diesel, and kerosene.
