Introduction to nitric acid storage tank
Nitric acid, with the molecular formula HNO3, is an inorganic acid with strong oxidizing and corrosive properties, and its anhydride is dinitrogen pentoxide. Nitric acid is less acidic than sulfuric acid and hydrochloric acid (PKa=-1.3), easily soluble in water, completely ionized in water, and its dilute solution is colorless and transparent at room temperature, while its concentrated solution is colorless and transparent. However, concentrated nitric acid is prone to decompose and produce nitrogen dioxide, which appears brown at room temperature. Nitric acid is unstable and prone to visible light decomposition. It should be stored in a dark place in a brown bottle and strictly prohibited from contact with reducing agents. Nitric acid is mainly produced by ammonia oxidation in industry, used to manufacture fertilizers, explosives, nitrates, etc. In organic chemistry, a mixture of concentrated nitric acid and concentrated sulfuric acid is an important nitration reagent.

Pure nitric acid is a colorless and transparent liquid, concentrated nitric acid is a colorless liquid (dissolved in nitrogen dioxide), and under normal circumstances it is a colorless and transparent liquid. There is a suffocating and irritating odor. The concentrated nitric acid content is about 68% and is easily volatile. The white mist produced in the air is small droplets of nitric acid formed by the combination of nitric acid vapor and water vapor. Exposure to light can produce nitrogen dioxide and turn it brown. Has strong acidity. Can turn wool fabrics and animal tissues into a tender yellow color. Can react violently with ethanol, turpentine, carbon, and other organic compounds. Can be miscible with water. Can form azeotropic mixtures with water. Relative density (d204) 1.41. Boiling point 120.5 ℃ (68%). Has strong oxidizing properties and reacts with metals other than gold and platinum to release nitrogen dioxide or nitric oxide. Has strong corrosiveness.
Based on the properties of nitric acid mentioned above, we know that nitric acid mainly exhibits the oxidizing nature of nitrate ions and belongs to the category of oxidizing acids. Nitric acid can directly dissolve the vast majority of metals. The mixed acid formed by concentrated hydrochloric acid and concentrated nitric acid in a ratio of 3:1 is called aqua regia, which can dissolve inert metals such as platinum. Therefore, nitric acid may have higher oxidizing properties in different environments. Although brown glass materials can resist nitric acid corrosion, the brittleness and transparency of glass can easily cause safety accidents tomorrow. Therefore, the choice of nitric acid storage tanks has been a concern for many entrepreneurs for a long time.
In 2006, Jinti Yongtong introduced steel lined PTFE anti-corrosion technology and used PTFE lining inside the steel shell to solve many problems in western chemical equipment. The PTFE lined nitric acid storage tank can hold nitric acid of any concentration, with excellent performance, no corrosion or leakage, safety and reliability, and a service life of more than 10 years.
