: Suggests venting or desiccant systems for storage tanks to prevent atmospheric moisture from diluting the acid and causing "vapor space corrosion". 3. Output & Risk Alerts
To develop a software feature based on (now updated to NACE SP0391 ), you should focus on automating material selection and risk assessment for handling concentrated (90% to 100%) sulfuric acid ( H2SO4cap H sub 2 cap S cap O sub 4 ) at ambient temperatures.

: Sulfuric acid forms a protective iron-sulfate film on steel. The standard explains that high-velocity flow (over 0.9 m/s) can physically strip this film away, leading to "erosion-corrosion". : Suggests venting or desiccant systems for storage
