Poor discharge in the stripping section
Thread Content
Let’s come and discuss this: there are always large fluctuations in the material feed rate to the stripping section, as well as significant variations in the density of the vertical pipes and the pressure drop across the plug valves! Coaxial two-piece!
It must have coked up; are the reaction temperatures fluctuating a lot?
It has just been overhauled, and there are very few coke lumps in the settler here!
It is recommended that, if possible, a trend chart of the relevant parameters be created and posted here; this will be more helpful for analyzing the issue you mentioned. :)
It seems that the cinders from the settler have fallen off and blocked the channels in the stripping section. If it can be ruled out as being that case, it is recommended to pay attention to the N2 content during drying – could there be a leak in the stripping section?
Or waiting for the riser piercing~~~?
Of course there will be fluctuations; variations in the inventory in the stripping section inevitably lead to fluctuations in the temperature of the regenerator. If the valve adjustments are not made in a timely manner, then the reaction temperature will naturally fluctuate as well!
We too, but we have two more, so it doesn’t make much of a difference
Check the relationship between the riser density and the stripping section density to see if there is a certain correlation, and then make a judgment~~~
One possibility is that the settler liner has come loose, resulting in obstruction in the gas section grid.
