The catalytic reaction stops the feed – how can the liquid level in the heavy oil distillation tower be maintained? The slurry is gone
How can fractionation occur during reaction cutting without a liquid level? Even if the product slurry transfer valve is not closed, wax oil can return to the distillation tower via the return line. Moreover, the slurry circulation cannot be interrupted without disrupting the fluidization of both devices.
Agree with the second-floor view. The reaction was shut down by cutting off the feed; only the feed oil supply to the nozzle was interrupted, and the feed oil returned to the distillation tower via the emergency return line. What circulates in the slurry is not just the slurry itself, but rather a mixture containing a large amount of crude oil. :lol
Are you diverting the material back to the crude oil tank or to the re-refining tank? In the case of oil slurry being discharged, is the liquid level in the distillation tower emptied as well?
The bottom liquid level of the tower can be controlled by adding raw materials, with particular attention to ensuring that the temperature at the tower bottom is not too low. Otherwise, it’s easy to get busy.
It is estimated that they did not return to the distillation tower as a result of an accident; normally, the feed is cut off and then sent back to the distillation tower. Nowadays, in many cases, the flow is directed directly to the crude oil tank and the re-refining tank. It seems that after the feed was cut off, the control over the flow of the oil slurry was inadequate. You can add wax oil to the bottom of the distillation tower. Through re-refining oil! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
