Top 10 Oil Refinery Suppliers in China 2025

Introduction to Oil Refinery

Oil refinery is a crucial industrial process that involves the transformation of crude oil into various useful petroleum products. Crude oil, as it is extracted from the ground, is a complex mixture of hydrocarbons and other impurities. The oil refinery process separates these components through a series of physical and chemical operations such as distillation, cracking, reforming, and treating. The end - products include gasoline, diesel, jet fuel, lubricants, asphalt, and many other petrochemicals that are essential for transportation, energy production, and various industrial applications.
