Salt formation in the top circulation system of the catalytic unit
Thread Content
Does the top circulation system of your catalytic unit experience salt deposition? Locations: 1. Filter at the inlet of the top circulation pump; 2. Top circulation heat exchanger; 3. Upper trays of the distillation column. Which of these locations is most prone to salt deposition?
I’m just here to see where salt tends to form
The inlet filter of the top circulation pump and the upper trays of the fractionation tower tend to accumulate salts easily.
At the top of our tower, salt has been formed at the exhaust outlet. It’s mainly related to temperature.
Salt deposition has occurred on several trays at the top of the distillation tower; this has happened many times
I’m aware of salt formation in this distillation tower. Have you encountered situations where the heat exchange efficiency is reduced due to issues with the heat exchangers?
Ammonium salts crystals, mainly ammonium hydrosulfide
The location where salt deposition occurs depends mainly on the temperature and flow rate; too low a temperature makes salt deposition more likely, and too slow a flow rate also facilitates salt deposition!
