Distillation column rerefining oil extraction temperature
Thread Content
Why is the extraction temperature of the fractionator regenerator oil sometimes almost the same as the vapor phase temperature at the chevron baffle?
The amount of slurry returning to the tower is low, and the temperature of the material returning to the tower is high.
Could this sea friend explain it in detail?
The amount of material returning to the top of the tower is low, which causes the gas-phase load at the bottom of the tower to increase; as a result, the temperature in the middle part of the tower rises. In other words, there is an imbalance between the gas and liquid phases.
I’m still very grateful to the original poster for sharing it~
Is there also a second re-refining system in the middle and lower sections?
The feed composition has changed. There are more light components. The ratio of light to heavy components on the tray is disrupted.
