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. Within the column, the crude oil vaporizes, and its components rise and condense at different levels according to their boiling points. Light fractions such as gases and naphtha are collected at the top, while heavier fractions like diesel, lubricating oils, and residue settle at the bottom. This step separates crude oil into basic fractions, but further processing is required to meet product specifications. After distillation, conversion processes are employed to transform heavier fractions into lighter, more valuable products. One important conversion method is cracking,
