The role of oil and its transformation to gasoline, oil and its conversion to gasoline, kerosene and chemicals processes and key equipment The role of oil Oil, also known as crude oil or black gold, is a thick, dark brown (petroleum, [1], sometimes a little green) liquid. The upper crust has oil reserves. The oil properties of different because of the producing areas. The density of 0.8 ~ 1 g / cm 3, a wide range of viscosity, freezing point difference (30 ~ -60 ~ C), boiling point range at room temperature to above 500 DEG C, soluble in various organic solvents, insoluble in water, but can form the emulsion with water. It consists of a mixture of different hydrocarbons, chemical composition of oil is mainly carbon (83% ~ 87%), hydrogen (11% ~ 14%), the remaining sulfur (0.06% ~ 0.8%), nitrogen (0.02% ~ 1.7%), oxygen (0.08% ~ 1.82%) and trace metals (nickel, vanadium, iron, etc.). Hydrocarbons composed of carbon and hydrogenated hydrocarbons constitute about 95% to 99% of the major components of petroleum. Compounds containing sulfur, oxygen, and nitrogen are harmful to petroleum products and should be removed as much as possible in petroleum processing. However, the composition and appearance of petroleum in different oilfields can be distinguished greatly. Petroleum is mainly used as fuel and gasoline, fuel oil and gasoline, which is one of the most important primary energy sources in the world. Oil is also a raw material for many chemicals, such as solutions, fertilizers, pesticides and plastics. Today, 88% of the oil is used as fuel, and the other 12% as raw material for the chemical industry. Processes and key equipment transformed into gasoline, kerosene and chemicals into gasoline, kerosene, and chemicals One of the processes of petroleum refin
