Regarding the control of diesel flash point in diesel stripping towers
Thread Content
The diesel stripper controls the flash point of diesel. With the amount of stripping steam remaining constant, does a lower liquid level in the stripping tower yield a better stripping effect, or does a higher liquid level achieve a better stripping effect? With all other parameters remaining the same, I personally believe that a higher liquid level yields a better stripping effect and increases the stripping time. But some people think that a lower liquid level works better, yet the reasons they give don’t convince me. If the liquid level is low, the steam will just pass through as soon as it enters; what kind of stripping effect can that possibly have? Some expert please convince me: handshake. . . . I have discussed this matter with many people; I am not convinced by their arguments, and they cannot convince me either. . .
Isn’t this just the problem of finding the optimal point? How high is the best level, and how low is the best level? It’s not a matter of a single variable; it cannot be determined through discussion alone – only through experimentation
Yes, one can’t just stick to their own opinions; it’s necessary to put them into practice and conduct experiments. Sometimes theory does not necessarily fully correspond to the actual situation of things.
As long as it meets the product specifications, there’s no need for anyone to persuade anyone else. Each has its own operating* habits. As long as the goal is achieved~~~
The level of the liquid has no effect on the flash point of light diesel; the view presented in the book is incorrect. A light diesel distillation column typically has 6 trays; steam and diesel come into countercurrent contact with each other, and what is the relationship between this and the liquid level?
By doing this, you are overturning the theory in the book
But sometimes, during operation, when the liquid level in the stripper fluctuates significantly, the flash point also fluctuates greatly. This phenomenon needs to be explained using scientific methods. One cannot seek comfort
Just make sure the liquid level isn’t so high as to flood the tower
Yes, but that constitutes abnormal production conditions.
Regarding this issue, which do you prefer? A higher liquid level? Low liquid level?
This doesn’t have much to do with the liquid level
