What type of oil is in the oil phase of the decanting oil-water separation tank?
Thread Content
As the title suggests, should there be more heavy diesel?
It’s mainly gasoline, right? Diesel is the one that comes next, I guess
There is another question: why does emulsification tend to occur in the degassing tank if the degassing temperature is controlled too low?
The oil phase in the top-cut oil-water separator is mainly composed of diesel components.

The classification of top-cut oil should be related to the type of refinery; for fuel-type applications, it should be heavy diesel, while for fuel-lubricant type applications, it can be either heavy diesel or a base oil for lubricants. It mainly depends on what purpose the fraction being cut is intended for. The oil in a degassing tank tends to emulsify at lower temperatures, as the separation of oil and water is less effective when the temperature is low; raising the temperature slightly can help with this separation process.
Diesel and gasoline do not require vacuum distillation.
It is mainly diesel, but with a relatively low initial boiling point and flash point, so there should also be a small amount of gasoline.
It is mainly heavy diesel, with a low flash point, a strong odor, and is volatile. With a low tower top temperature, the oil-water separation efficiency is poor, which naturally leads to emulsification.
If the temperature at the top of the tower is controlled too high, it is the wax oil that flows downward
