Is it caused by hydrogen sulfide? The pressure in the reflux tank is 0.5 kilograms, and the temperature at the reflux inlet is 20 degrees.
The temperature is too low. Are there crystals at the pump inlet?
Just inject demineralized water or deoxygenated water into the vapor line at the top of the tower for dilution! PS: Don’t you have this process?
There is a heat tracing line at the pump inlet that remains on all the time; we usually use external water to cool the pump body, and that gives much better results
What is the temperature of the heat trace medium? Based on your description, it is likely that the heat trace is heating the fluid in the inlet pipeline, causing partial vaporization and thus resulting in this problem. 1. Reduce the flow rate of the heat tracing medium ； 2. Lower the temperature of the heat trace medium.
