The refinery process is a series of industrial operations that convert crude oil into useful products like gasoline, diesel, and jet fuel. It involves several steps, including distillation, where crude oil is heated and separated into different components based on their boiling points. Other processes, such as cracking and reforming, further transform these components into higher-value products. After distillation, the separated components undergo additional treatments to remove impurities and enhance their quality. This may include processes like hydrotreating, which uses hydrogen to eliminate sulfur and other contaminants. The final products are then stored and distributed for use in various applications, including transportation and heating.
