1.1 Scope

This standard deals with the storage of sulfuric acids that can be handled in carbon steel equipment, i.e., sulfuric acid with concentrations above 70% and oleum up to 65% at temperatures up to 40°C (104°F). Typical industrial product concentrations are 93% and 98% sulfuric acid. Note: Storage tanks under 190 m3 (50,000 · gal U.S.) are outside the scope of this standard.

1.2 Objective

1.2.1 This standard provides industry guidelines for suitable storage facilities for sulfuric acid and oleum at atmospheric pressure.

1.2.2 This standard is based on good engineering practice. The underlying philosophy is that major failures can be avoided and minor incidents reduced to a minimum by ensuring a high degree of storage tank integrity through good design and construction, followed by adequate and regular inspection and maintenance.
