Corrosion protection for concentrated sulfuric acid dilution tank
Thread Content
I have a tank used for diluting concentrated sulfuric acid (98%), with dilute acid being used for the dilution process. The tank itself is made of stainless steel; is it feasible to use lead lining inside it? The original design called for a PTFE lining, but that’s no longer feasible; I’m thinking of switching to a lead lining or a fiberglass lining – which one is more reliable? Thank you!
Could the experts please give some advice? :handshake
The YKCH type graphite sulfuric acid diluter can be used to dilute concentrated sulfuric acid. This diluter enables the simultaneous dilution of concentrated sulfuric acid and cooling of the diluted sulfuric acid, with the outlet temperature of the diluted sulfuric acid remaining below 40 degrees. Sulfuric acid storage tanks can be made of steel-lined tanks or tanks made of non-metallic materials, depending on the concentration and volume of the acid.
Lead lining should be an option; you could also consider options such as graphite or PTFE lining, which should also give good results
