There is an abnormal noise at the bottom of the stripping tower; what’s going on?

A humming noise is heard at the bottom of the stripper, and this noise tends to increase in intensity. This could be caused by the following reasons: 1. **Gas leakage or cavitation**: If there is a leakage or cavitation phenomenon at the bottom of the tower, bubbles are formed, and the breakdown of these bubbles generates the humming noise. Given the tower pressure and steam conditions you mentioned, this possibility needs to be investigated. 2. **Mechanical failures**: If there are mechanical devices at the bottom of the tower, such as pumps or valves, their failures or damages can also cause unusual noises. Check whether these devices are operating properly. 3. **Structural resonance**: The tower itself or its internal components may enter a resonant state due to hydrodynamic effects, resulting in increased noise levels. 4. **Hydrodynamic instability**: Unstability may occur in the flow of steam and liquid within the tower, such as excessive flow speeds or collisions between them, which can also cause noise. It is recommended to conduct a thorough inspection of the stripping tower, including checking for leaks, monitoring the operation of the equipment, and examining the internal flow patterns; if necessary, seek professional assistance for a detailed diagnosis. .
