Abstract: The electrical desalting equipment of atmospheric and vacuum distillation unit is the first core equipment for crude oil processing. During the operation of the high-speed electrical desalting equipment of atmos-pheric and vacuum distillation unit, the abnormal running current of the electric desalting tank and the imbalance of electric field in the electric desalting tank caused by equipment fault will seriously affect the dewatering and desalination effects of electrical desalting equipment, bring adverse effects to the subsequent processing, and accelerate the downstream processing corrosion and other equipment failures. After the comparison and analysis of the structure principles and fault phenomenon of electrical desalting, the fault causes are accurately identified and the fault is solved in time. Through adding filtering facilities to the first-level electrical desalting inlet, optimizing the electric field structure and insulating the internal parts, the current and fault risks are reduced so as to ensure the safet and long-term operation of the highspeed electrical desalting equipment system.
