Is flooding a tower the same as liquid flooding?

\"Tower flooding\" and \"flooded trays\" mean roughly the same thing. In simple terms, \"flooded trays\" refer to the situation where individual trays are submerged in liquid, while \"tower flooding\" can be understood as all the trays below being immersed in liquid, which is a more severe condition than flooded trays.

Flooded towers are different from flooding; flooding occurs when one or all of the tray levels are submerged, and this concept is often used in design； A flooded tower can be understood as the lower trays (at least the bottommost ones) being submerged in liquid, which can easily cause the trays to flip over; this is a common occurrence during production.

Foaming is different from tower flooding; in foaming, only individual tray levels are filled with liquid, while tower flooding is much more severe, as the entire tower is filled with the liquid phase

The relevant information is from: http://baike.baidu.com/view/1291090.htm In gas-liquid reactors or mass transfer separation devices with counter-current contact, the gas flows from bottom to top. When the flow rate of the gas increases to a certain value, the liquid is prevented from flowing downward by the gas; it accumulates more and more until it overflows from the top of the tower, a phenomenon known as flooding. 　　The gas velocity or continuous phase velocity at which flooding occurs is called the flooding velocity ； This operating condition is known as the flooding point. When designing equipment, it is necessary to ensure that its operation does not lead to flooding. 　　For a tower of fixed diameter, the cross-section through which both gas and liquid phases can flow freely is limited. If the flow rate of either one of them increases to a certain level, the liquid in the downcomer cannot flow downward smoothly ； When the liquid in the tube rises to the top of the overflow weir on the upper plate, it will spill over onto that upper plate, resulting in abnormal accumulation of liquid; eventually, this can lead to the space between the two plates being filled with foam. This phenomenon is known as flooding, also referred to as tower flooding.

It seems one is more serious than the other~:lol

The severe consequence of flooding is the tower being submerged
