How to prevent static electricity when using a reactor

For hazardous chemical equipment such as reaction vessels, their ignition and explosion points are relatively low. If static electricity occurs, it is easy to cause hazards such as fire and explosion. Therefore, we need to take measures to prevent and avoid static electricity:
Control medium injection method: Inject medium from the bottom of the storage tank, although preventing medium injection from the top of the storage tank. If the missing medium needs to be injected from the top of the storage tank, the discharge port of the pipeline should be inserted into the tank at a depth of 200mm apart from the bottom of the tank; Control the flow rate of the medium. The higher the flow rate, the easier it is for static electricity to occur.
Injecting inert protective gas: In the tank, nitrogen is injected to protect it, reducing the nitrogen content inside the tank. This prevents explosive gas inclusions on the oil surface inside the tank. Even if static discharge sparks occur inside the tank, it can ensure the safety of the tank.
To prevent water and reaction vessel media from being mixed and transported together, to prevent differential media from being mixed and transported together, to prevent liquid media, oil and gas from being mixed and transported together with compressed air, the storage tank should be dehydrated vertically, and special attention should be paid to dehydration before feeding.
Crossing: The floating roof of a floating roof tank should be crossed with the tank wall. When insulation materials or erosion are used in pipelines, valves, flow meters, filters, pumps, and tanks, they should be cross connected. Grounding. Storage tanks and lonely and helpless individuals should be grounded, and a common grounding body should be used for lightning protection.
Electrostatic grounding measures: If there is some static electricity on the surface, if there is an electrostatic grounding device, the static electricity can be introduced underground, which can eliminate the danger of static electricity.
Installing an electrostatic scraper: Install an electrostatic scraper at the end of the pipeline, injecting charges with opposite polarity to those in the oil into the pipeline to complete charge neutralization and eliminate static electricity. Install an electrostatic eliminator. The reactor is installed with an electrostatic eliminator at the address after the filter and before the fluid passes through the storage tank.
Adding anti-static additives: By adding anti-static additives, the conductivity of the medium is greatly increased, preventing the accumulation of static charges inside the medium. It quickly leaks to the ground through a bridging load.
