The types of refined oil include fuel oil , kerosene , petroleum asphalt , petroleum coke , gasoline , diesel oil , lubricating oil , etc.
Here’s a brief introduction:
- Fuel oil
Used as fuel for boilers, ships and industrial furnaces. The viscosity of commercial fuel oil is used to distinguish different grades.
- Kerosene
The boiling point range is 180~310℃, mainly used for lighting and daily cooking. The flame is required to be stable and bright, without black smoke and with a small output.
- Petroleum asphalt
Mainly used for roads and buildings.
- Petroleum coke
Used as electrodes in metallurgy (steel, aluminum) and chemical (calcium carbide) industries.
- Gasoline
The most consumed variety. The boiling point range of gasoline is 30~205℃, and the density is 0.70~0.78 g/cm3. Commercially available gasoline is marked with an octane rating of 70, 80, 90 or higher, depending on the anti-knock combustion properties of the gasoline as it burns in the cylinder. Mainly used as fuel for cars, motorcycles, speedboats, helicopters and agricultural and forestry aircraft.
- Diesel
The boiling point ranges from 180 to 370°C and 350 to 410°C. For petroleum and its processed products, products with a lower boiling point or boiling point range are traditionally called light, and conversely, heavy. Therefore, the former is called light diesel and the latter is called heavy diesel. Commercial diesel oil is classified according to freezing point, such as 10, 0, -10, -20, etc., indicating the applicable ambient temperature. Diesel is widely used in vehicles (including trains), ships and diesel boilers using diesel internal combustion engines. Diesel demand is growing faster than gasoline because high-speed diesel engines (used in cars) are more fuel efficient than gasoline engines , and some small cars also use diesel.
- Lubricating oil
Lubricants made from petroleum account for more than 95% of total lubricant production. In addition to lubricating properties, it has cooling, sealing, corrosion protection, insulating, cleaning and energy transfer functions. Commercial lubricants are classified by viscosity. High viscosity oils are used for heavy duty, slow speed machinery. Instead, use a low viscosity oil. The oil refining unit produces base oils for various refining processes, plus a variety of additives, with special functions and high added value.
