There is an unusual noise coming from the tower bottom; have experts encountered this before?

In the hydrogenation unit, there is a humming noise coming from the bottom of the stripping tower, and this noise seems to be getting louder. The tower pressure is 0.25 MPa, and stripping steam at 1.0 MPa and 180°C is used.
The humming noise at the bottom of the stripping tower can be caused by several factors, including: 1. **Excessively high steam flow rate**: If the steam flow rate is too high, it may create vortices or shocks at the bottom of the tower, resulting in abnormal noises. 2. **Low liquid level**: When the liquid level is too low, steam comes into direct contact with the bottom of the tower, which may result in unstable gas-liquid mixing sounds. 3. **Structural resonance**: The tower or its internal components may experience resonance due to steam flow, especially when the steam pressure and temperature are high. 4. **Impurities or deposits**: If there are impurities or deposits inside the tower, they may generate additional noise as steam flows through it. Given the signs of an increasing volume, it is recommended to check the following: - **Check the liquid level control** to ensure it is within the normal range. - **Observe whether the pressure and temperature are stable**, and check for any abnormal fluctuations. - **Check whether the inside of the tower needs to be cleaned** to remove any possible impurities or deposits. If the problem persists, it is recommended to contact the equipment manufacturer or a professional technician for an on-site inspection and more in-depth analysis. .
6 units have just been installed. The design requires grouting holes to be made in the base plates; it is said that during the previous secondary grouting of the tower equipment, the grouting was not done properly, which caused abnormal noises in the tower. .
