1, avoid water, reaction kettle medium mixed co-transmission, avoid different medium mixed co-transmission, avoid liquid medium, oil and gas and compressed air co-transmission, storage tank to even dehydration, pay special attention to the feeding before dehydration; 2, cross. The floating roof of the floating roof tank shall be bridged with the tank wall. Pipelines shall be bridged with valves, flow meters, filters, pumps and tanks when insulating materials are used or corroded. 3. Grounding. The storage tank and isolated body shall be grounded, and the common grounding body can be grounded for lightning protection. 4. Control medium injection mode. Media should be injected from the bottom of the tank, and try to avoid injecting media from the top of the tank. If the medium to be injected from the top of the tank is missing, the discharge port of the pipe

1, avoid water, reaction kettle medium mixed co-transmission, avoid different media mixed co-transmission, avoid liquid medium, oil and gas and compressed air co-transmission, storage tank to even dehydration, pay special attention to dehydration before feeding;
2. Jumping. The floating roof of the floating roof tank shall be bridged with the tank wall. Pipelines shall be bridged with valves, flow meters, filters, pumps and tanks when insulating materials are used or corroded.
3. Grounding. The storage tank and isolated body shall be grounded, and the common grounding body can be grounded for lightning protection.
4. Control medium injection mode. Media should be injected from the bottom of the tank, and try to avoid injecting media from the top of the tank. If the medium is to be injected from the top of the tank, the discharge port of the pipe shall be inserted into the tank at a depth of 200mm from the bottom of the tank;
5. Control the medium flow rate. The greater the flow rate, the more likely it is to generate static electricity. The safe flow rate of the reactor oil in the pipeline v = 0.8(1/d)1/2 (d is the pipe diameter, V represents the average flow rate).
6. Fill inert protective gas. In the tank, nitrogen is filled to protect the tank, so that the nitrogen content in the tank is reduced, and explosive mixed gas cannot be formed on the oil surface in the tank. Even if electrostatic discharge sparks are generated in the tank, the safety of the tank can be ensured;
7. Add antistatic additives. The addition of anti-static additives greatly increases the conductivity of the medium, so that the static charge inside the medium cannot accumulate, and quickly leaks to the ground through the bridge charge.
8. Install static eliminator. A static eliminator is installed at the end of the pipeline, and the charge opposite to the polarity of the charge in the oil is injected into the pipeline to achieve charge neutralization and eliminate static electricity.
9. Install the static moderator. The reaction kettle is equipped with an electrostatic moderator after the filter and before the fluid enters the storage tank.
10. The reaction kettle controls the generation of human body static electricity and eliminates human body static electricity. On the tank personnel (sampling, metering, etc.) to touch the human body electrostatic device. Wear anti-static clothing.
