Will coking occur if the temperature of the liquid phase at the bottom of the distillation column is 400 degrees?
It tends to coking easily, but it’s not inevitable. It is related to factors such as time, the quality of the slurry in your equipment, and the flow conditions at the bottom of the tower. There was once a shutdown of the slurry circulation, and the temperature at the bottom of the tower briefly reached 400 degrees, but it returned to normal soon, with no significant consequences.
At 400 degrees, coking occurs quite easily, but it depends on how you make adjustments and on the residence time of the oil at the bottom of the tower
It definitely won’t work in the long term; if you don’t believe me, give it a try.
The temperature at the bottom of the distillation tower is 400 degrees, which is quite high and can lead to coking. However, other factors such as the residence time of the slurry at the bottom of the distillation column and the properties of the slurry also need to be considered, and a comprehensive evaluation is required. An increase in temperature directly affects coking at the bottom of the distillation column, and the rate of coking increases exponentially. However, short-term overheating has little impact on the long-term performance of the device.
