Storage tank for high concentration sulphuric acid
+++++++Hi
I want to ask what is the lining material(s) for carbon steel storage tank that stores sulphuric acid 78-96% concentration with 250 Deg C. Note storage tank has a lead lining and I want to change it by another lining.
what lining do you recommend for this tank?

Hi Vahid,
You sure seem to be using the right approach with a lead liner in a steel casing.
BUT if you opted for ambient temperatures, it would still be OK except then you could use some, not all, plastic materials.
Having been in plastic fabrications for quite a few decades,I wouldn't recommend any lining, not even teflon, not for 250° C !

Hi, Roma. Chemically pure lead would probably be resistant but is so soft that it can be a problem on large tanks. You might look into tin or antimony hardened lead alloy.
