What material should be used for the crystallization tank containing hydrochloric acid?
Thread Content
The material containing hydrochloric acid is cooled and crystallized in a crystallization tank; once crystallization occurs, the product is removed from the tank. The tank is equipped with a stirrer, and it is cooled using a jacket – the temperature can range from -15 to 200 degrees Celsius. The jacket is made of steel. What material would be suitable for use inside the tank? Is glass fiber reinforced plastic, enamel, CPVC, or some other material a good choice?
I used glass-lined steel on my last project.
Enameled material probably won’t work; I wonder if it’s feasible with such a large temperature range Give CPVC a try
Can two be used, one with a high temperature and one with a low temperature?
The glass-lined material has a limit temperature of 200°C and can withstand sudden temperature changes and cooling shocks
The temperature range is too wide; hasn’t anyone suggested using graphite?
Fiberglass is relatively viable; enamel can be used during the reaction process, but it is likely not suitable for crystallization. Why is there still hydrochloric acid in the crystal? Is it necessary to maintain a high acidity level? If the acidity is very low, high-quality stainless steel should also work, provided that proper passivation is carried out.
