What are the reasons for vaporization of the stabilizer tower top reflux pump? How to handle it?
Thread Content
Is the analysis incorrect, which suggests that salt deposition in the inlet filter causes low inlet pressure and a lower boiling point, thereby leading to vaporization?
It can be analyzed as follows: Salting out and blockage of the inlet filter result in low inlet pressure; the liquid temperature remains relatively constant. Since the inlet pressure is below the saturation vapor pressure, cavitation occurs； Low flow rate and high suction force can cause damage to the mechanical seal. Treatment: Switch the pump and clean the filter.
The imported filter should allow for separate removal and cleaning, right? Salty substances can generally be removed by simply rinsing them with water! I just think the issue of you not having salt should be resolved; otherwise, you’ll still have to do similar repetitive tasks in the future!

If salt accumulation occurs frequently, a deoxygenated water line can be added at the inlet to carry out regular flushing
If it is a catalytic cracking stabilizer, look for the cause in terms of operating procedures; after ruling out any changes in the feed composition, check whether the process parameters at the bottom and top of the tower deviate from those specified in the process sheet.
1. Clean the filter screen. 2. Increase the stabilizer column pressure and reduce the reflux temperature. 3. Open the outlet valve to an appropriate degree; don’t open it fully – just enough for the required flow.
