How to prevent static electricity in methanol storage tanks?
Normal electrostatic grounding is sufficient; cathodic protection is used when stricter requirements apply
In addition to controlling the flow rate to reduce static electricity generation through process measures, it relies mainly on the grounding protection system of the oil tank! ! !
It should be normal static electricity grounding; also, the internal floating plate inside the equipment needs to be grounded for static electricity purposes
Causes of static electricity in tank areas: (1) The resistivity of hazardous chemicals affects the generation of static electricity; (2) The methods used for loading and unloading hazardous chemicals can lead to static electricity; (3) Mixing different hazardous chemicals increases the amount of static electricity generated; (4) Water accumulated at the bottom of the tanks increases the amount of static electricity; (5) The time taken for static electricity to dissipate is also a factor. Grounding can effectively eliminate static electricity, and the use of anti-static coatings can also reduce its accumulation.
Oil tanks must be equipped with anti-static and lightning protection grounding systems; the pipelines, pumps, valves, etc. connected to them should also be grounded using aluminum materials.
I don’t know how the anti-static measures inside the storage tank are connected
