Hydrogenation tail oil properties

Hydrogenation tail oil refers to a by-product obtained from an oil refining unit in a hydrofining or hydrocracking process. Its composition is complex, mainly composed of long-chain alkanes and cycloalkanes, accompanied by a certain amount of aromatic hydrocarbons. Since most impurities such as sulfur, nitrogen and oxygen have been removed during the hydrotreating process, the quality of the hydrogenated tail oil is relatively high, with good chemical stability and low sulfur content. These properties make the hydrogenated tail oil have certain advantages in subsequent processing and utilization.

Hydrogenation tail oil use

Hydrogenated tail oil has a variety of uses and is widely used in chemical and energy fields. It can be used as a feedstock in refineries to produce petroleum products such as gasoline, diesel and jet fuel. Hydrogenated tail oil can be used as basic raw materials in chemical production to manufacture various chemical products such as solvents, lubricants, wax products, etc. Due to its high energy density and low pollution characteristics, hydrogenated tail oil is also used as industrial fuel and auxiliary fuel for power plants. In some special industrial applications, hydrogenation tail oil can also be used as a coolant and insulation material.

Upstream raw materials

The production of hydrogenated tail oil involves multiple upstream feedstocks. The first is crude oil, which is the most basic raw material for the production of hydrogenation tail oil. Crude oil undergoes primary processing, and the resulting light and heavy oils are the direct precursors of hydrogenated tail oil. The hydrogenation catalyst used in the oil refining process is also one of the key raw materials. These catalysts usually contain precious metals such as palladium, platinum, etc., which can promote the hydrogenation reaction and improve the quality and yield of the tail oil. The hydrogen required for the hydrogenation reaction is also one of the indispensable raw materials and is usually produced by cracking natural gas or heavy oil.

Downstream Feedstock

Hydrogenated tail oil has a wide range of downstream applications, involving multiple industries and products. First, in the fuel industry, hydrogenated tail oil can be further processed into high-quality diesel, gasoline and jet fuel for vehicles and aircraft. In the chemical industry, hydrogenated tail oil can be used to produce a variety of chemicals, such as synthetic lubricants, synthetic waxes, plastic additives and so on. The hydrogenated tail oil can also be used as a base oil for the production of lubricating oil manufacturers to produce high-performance lubricating oil products. In the field of environmental protection and energy, hydrogenated tail oil can be used as a clean fuel for industrial boilers and power plants to reduce pollutant emissions.

storage method

The storage method of hydrogenated tail oil needs to consider its chemical properties and safety. Because the hydrogenation tail oil has high stability, but also has certain volatility and flammability, fire prevention and explosion prevention measures must be taken during storage. Generally, hydrogenation tail oil should be stored in specially designed storage tanks. These storage tanks should have good sealing and corrosion resistance to prevent oil volatilization and leakage. Fire prevention facilities and leakage emergency treatment devices shall be provided around the storage tank to deal with sudden accidents. In order to ensure storage safety, the temperature and pressure of the storage tank should be kept within an appropriate range to avoid safety hazards caused by excessive temperature and pressure.

Environmental impact and treatment measures

Although the hydrogenation tail oil is relatively less contaminated during use, its production and storage may still have a certain impact on the environment. The first is the waste gas and waste water generated in the production process, if not handled properly, it may cause pollution to the air and water. Therefore, the refinery should be equipped with advanced waste gas treatment devices and sewage treatment systems to ensure that waste discharge standards. In the process of storage and transportation, it is necessary to prevent oil leakage and cause pollution to the environment. To this end, relevant enterprises should formulate strict operating specifications and emergency plans, strengthen staff training, and improve their ability to respond to emergencies.

future development trend

With the continuous improvement of environmental protection requirements and the adjustment of energy structure, the application prospect of hydrogenation tail oil is broad. In the future, with the advancement of hydrogenation technology and the development of new catalysts, the production efficiency and product quality of hydrogenated tail oil will be further improved. With the development of new energy and renewable energy, the application of hydrogenated tail oil in the field of clean energy will also get more attention. In order to respond to changes in market demand, relevant companies need to continue to innovate, optimize production processes, and improve product competitiveness.

Conclusion

As an important by-product in the oil refining industry, hydrogenation tail oil has a wide range of uses and good market prospects. Through the detailed analysis of its properties, uses, upstream and downstream raw materials and storage methods, it can be seen that hydrogenation tail oil has an important position in the chemical and energy fields. In order to achieve sustainable development, relevant enterprises need to continuously improve the technical level, optimize the production and storage process, reduce the impact on the environment, and promote the healthy development of the hydrogenation tail oil industry.
