Can anyone tell me if there is a required distance for a vapor control system unit from the peremeter of the containment wall on an ethonol tank (55,000 bbls)?
Refer to the equipment hazard ratings of all equipment that needs to be installed and locate each item in accordance with its rating and the area classification shown on your electrical hazard area classification drawing.
If you are talking about, how far away can I place non classified electrical equipment from a ethanol tank, this is covered in NEC and represented in API RP500.
