Sulfur content refers to the percentage of sulfur (sulfide or elemental sulfur) in crude oil. The sulfur content in crude oil is small, generally less than 65438 0%, but it has great influence on the properties of crude oil, corrosive to pipelines and harmful to human health. According to the different sulfur content, it can be divided into low sulfur or sulfur-containing petroleum.
Gum content refers to the percentage of gum contained in crude oil. The gum content of crude oil is generally between 5% and 20%. Gum refers to polycyclic aromatic hydrocarbons with relatively large molecular weight (300- 1000) in crude oil, which contains elements such as oxygen, nitrogen and sulfur, and is dissolved in crude oil in the form of semi-solid dispersion. Colloids are easily soluble in organic solvents such as petroleum ether, lubricating oil, gasoline and chloroform.
The asphaltene content in crude oil is less, generally less than 65438 0%. Asphaltene is a black solid substance with high molecular weight (greater than 1000) and polycyclic structure. Insoluble in ethanol and petroleum ether, soluble in benzene, chloroform and carbon disulfide. When the asphaltene content increases, the quality of crude oil deteriorates.
Hydrocarbons in crude oil are mainly divided into alkanes, cycloalkanes and aromatics. According to the different composition of hydrocarbons, it can be divided into three types: paraffin-based oil, naphthenic base oil and intermediate base oil. Paraffin-based petroleum contains more alkanes; Cycloalkyl petroleum contains more naphthenes and aromatics; Intermediate base oil is between the two. The crude oil that has been exploited in China is mainly based on low sulfur paraffin. Crude oil in Daqing and other places belongs to this category. Among them, the most representative Daqing crude oil has low sulfur content, high wax content and high freezing point, which can produce high-quality kerosene, diesel oil, solvent oil, lubricating oil and industrial paraffin. Shengli crude oil has high gum content (29%), high specific gravity (about 0.9 1) and high wax content (about 15-2 1%), which belongs to the sulfur-bearing intermediate group. Gasoline fraction has good lead sensitivity and is rich in naphthenes and aromatics, so it is a good reforming raw material.
