What are the reasons for the excessively high salt content in crude oil after electrodialysis desalination, and what are the solutions?
Furthermore, it is determined by the properties of the raw materials; the amount of water injected needs to be adjusted accordingly
The properties of crude oil cannot be adjusted. Generally, adjustments are made in terms of the dosage used for demulsification and the type of agent selected, as well as the amount of water injected and its properties, the intensity of mixing, the processing volume, and the electric field strength. These factors are also influenced by current levels, interfacial conditions, and water separation efficiency. It may be sufficient to adjust just one or two of these parameters, but even adjusting all of them might not be enough to meet the requirements. The maximum desalination rate achievable by an electrodesalination system is essentially fixed; if the salt content is too high from the outset, it may not be possible to achieve the desired results.
Mixed strength, electric field strength, demulsifier, water injection volume, interfacial level height, and so on
When the salt content is high, water tends to remain after desalination; this allows for an increase in settling time by avoiding water injection at the third stage
