What are the reasons for liquid flooding in the urea decomposition tower?

I’m a beginner, and I hope everyone can give me a detailed explanation. I really want to learn more knowledge
In my opinion, the main reasons for flooding are: 1. The vapor-liquid ratio in the separation system is incorrect； 2. The amount of steam added is too high, causing the liquid to be blown directly to the top of the tower ； 3. Excessive system load during parsing ； 4. Problems with the internal components (problems with the tray or packing)
The answer is very thorough; to add, high ammonia concentration in the desorption solution can also cause spilling.
