What Is a Tank Farm?

All enterprises and units used to receive, store and distribute crude oil or crude oil products are called oil depots. At the same time, the oil depot also refers to special equipment used to store oil. Because of the specificity of the oil, it is used for storage in the corresponding oil depot. The oil depot is the link that coordinates the production of crude oil, processing of crude oil, and the supply and transportation of refined oil. It is also the base of national oil reserves and supply.

Oil depot

1. The production base is used to accumulate or transfer oil;

2. The supply and marketing department is used to balance consumption and circulation;

3. The enterprise sector is used to ensure production;

4. National strategic reserves.

Oil depots store flammable crude oil and petroleum products. Most stores gasoline,

With the rapid development of China's petroleum industry, the development of oil depots is also fast. In addition to a series of special oil depots built in the petroleum system, supply and marketing systems, and military systems, other enterprises, such as railways, transportation, power, metallurgy and other departments have also established various types. Oil depot to ensure the normal operation of transportation and production.
