What is the cause of the bulging deformation in layers 6, 7, and 8 of the CO2 stripping urea synthesis tower trays? The deformation is quite severe; could someone analyze the reason for this?
It’s best to post photos from the scene. It is caused either by radial compression on the tray or by an upward impact (such as excessive feeding or rapid pressure increase)
I agree with the analysis from a user upstairs. Typical urea plants operate at full capacity, with a gas-liquid two-phase flow inside the synthesis tower; when the gas and liquid loads exceed the design limits of the trays, phenomena such as tray deformation can occur.
