Catalysis, regeneration of inclined tube fluidization issues
Thread Content
After the unit was modified, the regenerative fluidization has not been good, with the slide valve pressure drop being below 20. What are the principles for adjusting the loose components? Thank you????
So is the opening degree of your regenerative slide valve very large? Ours is at 60 Kpa
We set the regeneration opening at 40-50, with a pressure drop of 10-20. The density of the inclined tubes is over 500
The density isn’t high. How do you determine that fluidization is not good? Is it due to large variations in the opening degree of the regenerative slide valve?
A too-large opening of the slide valve, insufficient pushing force from the inclined tube, catalyst bridging, and so on are all possible possibilities; try loosening some components and increasing the volume of the second fixed-bed layer
I have a set of equipment that allows me to conduct on-site inspections, make judgments, and then provide you with recommendations.
