Introduction to Oil Refiner

An oil refiner is a facility that processes crude oil into various useful petroleum products. The refining process involves a series of complex chemical and physical operations, such as distillation, cracking, reforming, and treating. These operations help to separate the different components of crude oil and transform them into valuable products like gasoline, diesel, jet fuel, lubricants, and petrochemical feedstocks. Oil refineries play a crucial role in the global energy supply chain, as they bridge the gap between the extraction of crude oil and the consumption of refined products by industries, transportation, and households.
