How to achieve static grounding for a glass-lined reactor?
Thread Content
The medium is methanol and toluene; the reaction temperature is room temperature, and stirring is employed. How can static electricity be dissipated?
Install conductive copper foil through the equipment manhole screws or other locations on the equipment, and ground it
Does it need to extend below the liquid surface? Otherwise, the enamel coating on the inside of the tank will also be non-conductive
I’m sorry; I just asked the person in charge of electrical matters, and they said that for non-metallic pipes and equipment, enamel also falls under this category, and there’s no need for static discharge protection since they are insulating by nature. Therefore, providing static discharge protection is unnecessary. The specifications only require the grounding of metal pipes and equipment. :L
That’s right; it’s not possible to discharge the static electricity from the outer wall. In such situations, with toluene present inside the reactor along with stirring, static electricity is generated very easily. When this static electricity accumulates, and given that it’s a pressure vessel without a nitrogen seal, it can catch fire in contact with oxygen. So, we need to find a way to discharge that static electricity
