◪Increase Humidity Appropriately
In humid environments, static electricity is very unlikely to occur. Therefore, increasing the relative humidity in the working area of the reactor is one of the effective ways to prevent static electricity, Normally, controlling the humidity above 30% can greatly reduce the generation of static electricity.
◪Use Conductive Materials
Using conductive materials is another effective way to prevent static electricity. You can try to use conductive materials such as copper, iron and aluminum to build a reactor, and ensure that there is good contact between the objects so that electrons can flow through contact.
◪Install A Static Eliminator
Install a static eliminator at the end of the pipeline to inject charges with opposite polarity to those in the oil to achieve charge neutralization and eliminate static electricity.
◪Control The Medium Injection Method
The medium should be injected from the bottom of the reactor and try to avoid injecting the medium from the top. If the medium is to be injected from the top, the outlet of the pipe should be inserted into the tank to a depth of 200mm from the bottom of the tank.
◪Control The Medium Flow Rate
The greater the flow rate, the easier it is to generate static electricity. The safe flow rate of oil in the pipeline is v=0.8(1/d)1/2 (d is the diameter of the pipe, and v represents the average flow rate).
◪Avoid Mixing and Transporting Water and Medium
Avoid mixing and co-transporting different media, and avoid co-transmitting liquid media, oil and gas, and compressed air. The storage tank must be dehydrated in time, and special attention must be paid to dehydration before feeding.
◪Fill With Inert Protective Gas
When the reactor is filled with nitrogen for protection, explosive mixed gases will not from on the oil surface in the tank. Even if static electricity and sparks are generated in the tank, the safety of the reactor can be ensured.
◪Jumper
The floating roof of reactor should be connected to the tank wall, and the pipelines should be connected to valves, flow meters, filters, pumps and tanks when insulating materials are used or are corroded.
◪Grounding
Reactors and isolated bodies must be grounded, and a public grounding body can be used for lightning protection.
◪Control the Generation and Elimination of Human Body Static Electricity
Technicians (sampling, measuring, etc.) must first touch the human body's electrostatic devices and wear anti-static clothing.
◪Add Antistatic Additives
Adding antostatic additives greatly increases the conductivity of the medium, so that the electrostatic charge inside the medium cannot accumulate and quickly leak to the earth through the jumper load grounding.
◪Reasonably Arrange the Order of Operations
Most static electricity is generated by the separation of liquids, instantaneous vaporization, etc. Therefore, before using the reactor, air and gas removal, cleaning and drying must be carried out in advance to eliminate potential static electricity hazards in reactor.
