Pipeline vibration
Thread Content
The methanol-rich stream from the bottom of the H2S concentration tower enters E1609 via the P1603 pump, undergoes heat exchange in the shell side of E1609, then enters the tube side of E1610, and subsequently goes to the thermal regeneration tower. The pipeline from outlet E1609 to the thermal regeneration tower experiences significant vibration; could it be due to gas-liquid two-phase flow? Is there a good solution?
The diameter of the tube running vertically upward from the heat exchanger is not appropriate (it might be a bit too large). ), a two-phase gas-liquid flow forms an plug flow.
Are there any specific photos? It’s not clear sometimes
Is the flow rate of pump P1603 stable? Check if the pressure gauge at the outlet of pump P1603 is fluctuating
1. There are no operating conditions, no drawings, no photos – everything mentioned is just speculation; these parameters need to be provided； 2. Where is the vibration source? ； 3. How is the support set up? ；
There may be an impact from two-phase flow; it might be worth trying to install dampers at an appropriate location on the pump outlet in order to reduce pipeline vibration
It is likely that two-phase flow is occurring. Our plant uses Linde’s process, the level control valve is located relatively close to the regeneration tower, so the pipelines do not vibrate much
