Material selection for acidic waste liquid storage tanks
Thread Content
I need to design a storage tank that operates at near-atmospheric pressure, but is used to store waste acid containing SO4²¯, NO3﹣, and Cl- ions. Dear forum members, what material would be the most suitable for this purpose? Is stainless steel still the steel used for ordinary pressure vessels, but with appropriate acid resistance treatment applied?
In other words, pressure-resistant materials such as Q245R can be used, and the interior can be lined – is that what it means?
Check the volume. For smaller ones, use plain stainless steel; for larger ones, consider composite panels, linings, anti-corrosion coatings, etc.
If the temperature is not too high, around 50 to 60 degrees, fiberglass can be used as it is inexpensive.
