Hello there:

 

What is the cheapest but compatible material of construction for Sulphuric Acid storage at varying concentration? My process is going to see varying concentration of H2SO4 from 1% to 98%. What material of construction would be best for the application?

 

Thanks you

Hi,

 

In general:

 

Polyethylene

Polypropylene

Fiberglass

Stainless steel

Hi,

Consider the brochures attached. Make sure the material is suitable for sulfuric (safety). Cost should not be the driver.

Temperature? Volume? Impurities?

No so great with stainless steel al lower concs. Thanks

Temperature? Volume? Impurities?

From 5 C to 100 C, upto 100,000 USGal, Water mostly

From 5 C to 100 C

 

 

concentration of H2SO4 from 1% to 98%. 

 

You are here 

 

 

region 80-85% @ 100°C governs material choice: glass, tantalum, silicon iron

 

 

 

Temperature? Volume? Impurities?

upto 100,000 USGal,

 

 

The largest glass-lined vessel I have encountered was ~10k USG. 

 

 

 

Temperature? Volume? Impurities?

Water mostly

 

 

 Impurities are still critical, e.g. 50 ppmw of chlor-ion affect some materials.

 

Advice

Seems you have no options other than avoiding critical regions in corrosion chart by controlling temperature. We have a positive experience with 316L in similar environment if equipment&piping had been properly designed and manufactured - service life of equipment&piping was 5-10 years.

Hi,

Data from a reputable company.

Note: You may have to segregate your streams and consider different Storage tanks for different concentrations.
