Is a stripping tower surge equivalent to a full-liquid condition? What’s the difference?
This is a basic phenomenon of distillation; you can take a look at Principles of Chemical Engineering. That is, the difference between tower flushing and tower flooding
The most fundamental concept here is \"tower flooding,\" also known as \"liquid flooding\" – these two concepts are the most basic in the principles of chemical engineering. Then it’s this: first there’s the “tower flooding,” and only when it gets worse does the tower become full. Finally, tower flooding occurs only when there is sufficient upward driving force in the gas phase (in terms of volume, pressure, and pressure difference).
“If we understand \"tower flooding\" as \"liquid overflow,\" that doesn’t make sense. Tower flooding is caused by an increase in liquid level, while liquid overflow occurs when the amount of steam suddenly increases, leading to the \"lifting\" of the liquid phase.
To be precise, tower flooding and tower washing are two phenomena that occur together; generally, after flooding occurs, when the gas phase accumulates to a certain extent, it will inevitably break through the liquid layer. In other words, these two phenomena take place in certain areas of the tower, and overall this is caused by the disruption of the gas-liquid phase equilibrium.
