Nitric acid and water form an azeotropic mixture, with a maximum boiling point of 395 K, containing ca 68% nitric acid by mass; thus the concentrated acid cannot be obtained by distillation of the aqueous solution. Concentrated sulfuric acid is used to absorb the water content and then on distillation of this mixture, concentrated nitric acid is obtained. Pure nitric acid boils at 359 K.

The heart of the nitric acid plant is the catalytic reactor where the mixture of ammonia and air reacts to form nitrogen monoxide, on a Pt/Rh catalyst. The catalyst comprises several layers of fine PlatinumRhodium (95%Pt and 5%Rh) mesh and the gases flow through this. Pt/Rh 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O ∆H = 903 kJ 890°C, 34 atm The catalyst gauzes are initially heated using a ...
Corrosion behavior of SUS316L in nitric acid solution containing seawater components Yuichi SANO1, Hiromu AMBAI2, ... During the Fukushima Daiichi nuclear power plant accident, significant volume of seawater was injected into the storage pool for spent nuclear fuel as the coolant. If this contaminated spent fuel is reprocessed, some components of the seawater will be mixed with HNO 3 .
Nitric Acid Plants. Three nitric acid plants operate at the Kooragang Island site, converting ammonia into approximately 330,000 tonnes of nitric acid per annum. Manufacturing process . In the nitric acid plants, ammonia is vapourised and then mixed with compressed air before being passed over a catalyst in a converter to form nitrogen oxides ...
Concentrated nitric acid and its vapors are highly corrosive to the eyes, skin, and mucous membranes. Dilute solutions cause mild skin irritation and hardening of the epidermis. Contact with concentrated nitric acid stains the skin yellow and produces deep painful burns. Eye contact can cause severe burns and permanent damage. Inhalation of high concentrations can lead to severe respiratory ...
