Question: What is “leakage”? Answer: When the processing capacity of the tower is too low, the gas velocity inside the tower is very low. Under the effect of gravity, the liquid phase flows downward through the valve openings without coming into contact with the gas phase, resulting in no mass or heat transfer – this phenomenon is known as \"liquid leakage\".
In a sieve tray tower, during the gas-liquid contact process, when the gas velocity is low, some of the liquid drops directly through the sieve holes. Severe leakage prevents liquid from accumulating on the sieve, thereby preventing normal operation. To avoid leakage, it is necessary to ensure even gas distribution so that gas can pass through each sieve hole. To ensure uniform gas distribution, the sieve plate structure should be designed properly, and an excessively low gas velocity should be avoided.
When the tower’s processing capacity is too low, the gas velocity inside the tower is very low; under the effect of gravity, the liquid phase flows downward through the valve openings without coming into contact with the gas phase, and thus no mass or heat transfer occurs – this phenomenon is known as \"liquid leakage\".

When the gas load is too low, the gas velocity is also low; the gas flow is not sufficient to support the liquid flow, resulting in the liquid on the tray leaking to the lower tray.
