Nitric acid >70% applications
The most important industrial use of nitric acid is the preparation of the salt ammonium nitrate, NH4NO3, which is used in the manufacture of fertilizers and explosives. In fact, more than 80% of the nitric acid produced annually is devoted to the preparation of fertilizers.
Among the many important reactions of nitric acid are neutralization with ammonia to form ammonium nitrate, a major component of fertilizers; nitration of glycerol and toluene, forming the explosives nitroglycerin and trinitrotoluene (TNT). Nitroglycerin (the explosive component of dynamite) is made by adding nitric and sulphuric acids to glycerol under very carefully controlled conditions.
Nitric acid is an oxidizer, when carried in a stainless steel tank container, purging air from the tank container will not stop the stainless steel from getting corroded because Nitric acid contains its own oxygen. Nitric acid reacts violently with many non-metallic compounds, and some reactions may result in explosions.
High concentration Nitric acid is incompatible with most materials, tank material, seals, gaskets, and linings. For seals and linings, only PTFE will b resistant.
For tank shell material special grade steel Uranus S1 stainless steel and aluminum lined tank containers have adequate resistant.
