What are the main light components in the overhead stream of the diesel hydrocracking hydrogen sulfide removal stripping tower?
Thread Content
Currently, the liquid level in the stripping tower is high, the amount of reflux is large, the temperature of the stripping tower is low, and the flow rate of the oil from the bottom of the stripping tower to the distillation tower fluctuates significantly; however, there is no significant increase in the light components at the top of the distillation tower. Why is this? . .
The reflux components we use are generally below C5; the reflux temperature in the stripping column has likely changed, which is why the reflux volume has increased as well.
Have you encountered the situation where high backflow leads to jagged fluctuations in the flow rate of the oil at the bottom of the stripping tower? . .
