Issues with 97% nitric acid storage tanks
Thread Content
Dear experts, may I ask what materials should be used for storing 97% nitric acid, and what format is suitable (horizontal or vertical)? What standards can be referred to? Also, what materials and formats are appropriate for transfer pumps?
For aluminum tanks, the pumps can be made of C4 steel or lined with fluorocarbon.
Either vertical or horizontal is acceptable; for larger tanks, a horizontal configuration is recommended as aluminum tanks lack sufficient strength
The corrosion manual should contain information on material selection
Generally, aluminum cans with a flat bottom and conical or domed top at atmospheric pressure are used; their height-to-diameter ratio is low, and their height should not be too great. Horizontal storage tanks are also used.
