Regarding the dehydration operation in the vacuum distillation tower
Thread Content
The vacuum distillation tower in our facility is designed for processing heavy oil, with a low load at the top of the tower. Now, there is a batch of heavy oil with a high water content that needs to be dehydrated using this vacuum distillation tower. I’m just starting to work with atmospheric and vacuum distillation units; could you all tell me whether it’s only possible to carry out cyclic dehydration of the contaminated oil, or if it’s also possible to use the first stage of the vacuum distillation process?
Is there electrodialysis ahead? If the water content is high, remove some water through electrodialysis.
Without an electrodialysis unit, the material goes directly from the tank area to the tower after passing through the heating furnace
Personally, it is recommended to avoid dehydration in the tower as much as possible; if it is necessary to use the tower, then the mixing ratio should be controlled.
A large amount of water has already been removed in the regular tower
The initial distillation tower can perform an excellent dehydrating function
Is there no relevant precedent for reducing water intake by one level, or is it not feasible?
Due to various constraints, we skipped the initial distillation column

Can water only come out from the top of the tower?
