Electrodesalination tripping issue
Thread Content
Dear experts in the marine field, during accident handling, the pressure in the electrodialysis tank dropped significantly, and the system tripped despite no change in current. What could be the reason? ?
1. High water level in the system. 2. Severe emulsification layer. 3. Poor separation of crude oil and heavy oil from water. 4. Sudden increase in water injection volume. 5. Problems with the electrical components themselves
Mainly, the current didn’t change; it just tripped immediately. I don’t understand why a change in pressure would cause an immediate trip
Firstly, regarding changes in current, in the devices I have worked with so far, it is common for there to be variations in current in AC and DC electric fields; for example, when there are changes in the moisture content of the raw materials or in their properties, the current changes significantly. However, in the case of pulsed signals, there are basically no such changes. Secondly, regarding pressure drop and transformer tripping, it is usually the desalination tank equipped with a low liquid level switch; when the pressure drops, the oil and gas or moisture in the tank vaporize, triggering the low liquid level interlock protection, which in turn causes the transformer to stop operating. They are all personal opinions; please forgive any humor in them.
