Design, Fabrication, and Inspection of Storage Tank Systems for Concentrated Fresh and Process Sulfuric Acid and Oleum at Ambient Temperatures

This standard provides recommended design, fabrication, and inspection practices for maintaining the mechanical integrity and minimizing the potential occurrence of undetected corrosion in concentrated fresh sulfuric acid tanks, process sulfuric acid tanks, or oleum storage tanks at atmospheric and low pressure. Inspection guidelines that aid in detecting and monitoring corrosion are presented, with the overall aim being to avert catastrophic failures. This standard is intended for use by sulfuric acid manufacturers and end users that have stationary sulfuric acid storage tank systems. Rail tank cars, tank trailers, barges, and portable tote containers for sulfuric acid are not within the scope of this standard. The standard may be used by personnel in many types of roles, including inspectors, plant maintenance personnel, plant engineers, consulting engineers, contract services personnel, etc. A wide variety of industries use sulfuric acid including, but not limited to, the chemical processing, agricultural, pharmaceutical, and hydrocarbon processing industries.
