The process of petroleum refining involves a series of steps aimed at converting crude oil into useful products such as gasoline, diesel, kerosene, lubricants, and petrochemicals. Refining begins with the physical and chemical separation of hydrocarbons based on their boiling points, chemical composition, and molecular structures. The first step in petroleum refining is crude oil distillation, also known as atmospheric distillation. In this process, crude oil is heated in a furnace to a high temperature, typically between 350°C to 400°C, and then fed into a distillation column.
