Oil antistatic agent which plays an important role in oil refinery

Oil antistatic agents are usually used in oil storage, transportation, treatment and loading in refining plants to reduce static electricity generation and accumulation and prevent static sparks from causing fire and explosion.

Why do the storage, transportation, handling and loading of oil in refining plants produce static electricity?

First of all, many refining plants produce and process oil products with high electrical conductivity and resistivity, especially refined petroleum products. This type of oil is easily charged in the process of flowing, stirring, dripping, etc., because they are inherently conductive.

Secondly, because of friction and flow, friction charges are generated during the flow and friction of oil products in transportation pipelines and equipment. When the oil is rubbed with the container, pipe wall, filter media and other objects during the flow process, the electron transfer between the friction surface will lead to charge separation, that is, the generation of positive and negative charges.

At the same time, in some processing devices, the oil may be separated, heated, cooled, condensate and other operations, so that some components contact the interface, resulting in the separation and accumulation of electric charges.

The formation of electrostatic accumulation, because the oil itself is not conductive to static electricity, so static electricity is easy to accumulate on the surface of the oil. Especially in low humidity, dry environment, charge is difficult to quickly disperse, resulting in the accumulation of static electricity.

The generation and accumulation of static electricity can easily cause fires and explosions in refining plants, because electrostatic discharge can trigger the ignition of flammable substances such as combustible gas or steam. Therefore, a series of anti-static measures need to be taken in the refinery, such as the use of antistatic agents, grounding devices, static eliminator, etc., to reduce the generation and accumulation of static electricity and ensure the safety of the operating environment.

In the refining plant, the main links of the use of oil antistatic agents include:

1. Oil storage tank: Oil storage tank is the main place for oil storage, and static electricity is easy to accumulate here. By adding antistatic agents, the electric charge on the surface of the oil can be reduced, reducing the possibility of electrostatic generation.

2. Conveying pipeline: the oil passes through the pipeline during conveying, and the friction and flow along the way will produce static electricity. Adding antistatic agents to the delivery line can reduce the buildup of static electricity and reduce the risk of fire caused by static sparks.

3. Processing device: Oil products are separated, heated, cooled and other operations in various processing devices, which may also lead to static electricity. The use of antistatic agents ensures that no dangerous electrostatic discharge is generated during these operations.

4. Loading and unloading: The loading of oil from storage tanks to transport vehicles or vessels, as well as unloading from transport vehicles into storage tanks, requires careful handling of static electricity. Antistatic agents reduce static buildup during loading and unloading, ensuring safe operation.

Methods of using oil antistatic agents usually include:

The first step is to add the antistatic agent to the oil: the antistatic agent can be added to the oil by the appropriate proportion. The specific dosage needs to be determined according to the type of oil, environmental conditions and requirements.

The second step, mixing and stirring: once the antistatic agent is added to the oil, it is necessary to fully mix and stir to ensure that the antistatic agent is evenly dispersed in the oil.

The third step, regular inspection and maintenance: the refinery needs to regularly check the effect of antistatic agents, and supplement as needed. At the same time, it is necessary to ensure that the antistatic agent used meets the relevant safety and environmental standards.

In particular, oil antistatic agents play an important safety role in refining plants, greatly helping to reduce static electricity generation and accumulation, reducing the risk of electrostatic fire and explosion.
