Polyethylene gas-phase fluidized bed distributor plate clogging: phenomena and countermeasures
Thread Content
The pressure difference across the distribution plates is already 40+; there’s only a little amount of material left, and I can’t figure it out
Is it the gas-phase fluidized bed UNIPOL process? Take a look at the core table inspection status on the distribution board to see if there are any issues. Is the fluidization operating normally?
It depends on how you proceed; describe the process of increasing the pressure difference across the distribution plate, as well as what happens when the fluidized bed starts to be used
