What type of storage tank should be used for sulfuric acid at this concentration?
Thread Content
Dear experts, I have a question: my company has sulfuric acid with a concentration of around 75%, at a temperature of about 50 degrees. What type of storage tank would be suitable for storing this sulfuric acid? The tank needs to have a capacity of around 50 cubic meters. Tanks with a steel lining covered in PTFE are quite expensive; can fiberglass material handle sulfuric acid at this concentration and temperature? I welcome everyone's advice.
The critical temperature of 50° is awkward. . . It is recommended to use steel lined with rubber, PE, or PTFE – the choice depends on economic considerations
Acid-resistant lining bricks will do; even if there is a leak, it can be fixed by applying glue.
FRP can be used, but the resin for the lining must be phenolic vinyl resin; ordinary bisphenol A vinyl resin cannot be used. I specialize in anti-corrosion resins; if you have any questions, feel free to call me at 15952481518
PVC+FRP materials meet the requirements; we have been using them for many years, and none of the units we’ve used have had any problems.
It is recommended to use an F4 steel lining; it is more expensive. Remember: safety comes first. It’s impossible to control problems that arise due to such acidity and temperature levels, unless you have a backup system in place
