Chemicals That Tend to Crystallize?
(OP)
We have a project feeding several traditional water treatment chemicals listed below:
Sodium Hydroxide (Caustic Soda) - 50%
Sodium Hypochlorite - 12.5%
Hydrofluosilicic Acid - 18%
Ferric Chloride (coagulant) - 25%
I am looking for a source of information to find out which chemicals tend to crystalize and at what temperatures? Caustic Soda seems to be a consistent concern, but have heard different things about the others, esp. Ferric Chloride. Any help? Also, is heat trace and/or insulation usually enough?

Good luck

Now sodium hydroxide on the other hand is a different story.
We keep our storage tank at around 100F and we do use heat tape and insulation on the majority of our piping. If it is going to be in a cooler enviroment I would suggest on doing the same or the caustic lines will freeze up.
