Oil refining is the process of transforming crude oil into useful products like gasoline, diesel, and jet fuel. This involves separating the different components of crude oil through a method called distillation. During distillation, the oil is heated, and its various parts are collected at different temperatures, allowing for the extraction of valuable fuels and other materials. After distillation, further processes like cracking and reforming are used to improve the quality of the fuels and create additional products, such as lubricants and asphalt. The refined products are then distributed to gas stations and other facilities, making them essential for transportation and industry.
