Pure Nitrogen

N₂

Pure Nitrogen is used in large quantities in the chemical industry for blanketing, purging and pressure transfer of flammable chemicals.

High purity nitrogen is used in large quantities by the semiconductor industry as a purge or carrier gas as well as for blanketing equipment such as furnaces when not in production.

Pure Nitrogen is a colorless, odorless, tasteless and non-toxic inert gas. Liquid nitrogen is colorless. The relative density of gas at 21.1℃ and 101.3kPa is 0.967. Nitrogen is not flammable. It can combine with some particularly active metals such as lithium and magnesium to form nitrides, and can also combine with hydrogen, oxygen and other elements at high temperatures. Pure Nitrogen is a simple asphyxiant.

N₂

Pure Nitrogen

Pure Nitrogen is produced in large quantities at air separation plants which liquefy and subsequently distil air into nitrogen, oxygen and usually argon. If very high purity nitrogen is required the nitrogen produced may need to go through a secondary purification process. The lower range of nitrogen purities can also be produced with membrane techniques, and medium to high purities with pressure swing adsorption (PSA) techniques.

Application

Engineering / Construction

JINHONG GAS provides high-purity specialty gas solutions for the engineering and construction industries, such as nitrogen, argon, and hydrogen, which are widely used in welding, cutting, concrete curing, and fire protection systems, helping projects improve construction quality and safety efficiency.

Food / Medical

Medical gases are gases used in medical procedures. Mainly used for therapy, anesthesia, driving medical equipment and tools. Commonly used gases are: oxygen, nitrogen, nitrous oxide, argon, helium, carbon dioxide and compressed air.

Manufacturing

Industrial gases are known as the “blood” of industry. Industrial gases are generally in high demand, but do not require high purity.A large amount of industrial gases are required in metallurgy, steel, petroleum, chemical, machinery, electronics, glass, ceramics, building materials, construction, food processing, medicine and medical and other industries,

FAQs

High-purity nitrogen is used as protective gas and carrier gas in the manufacture of integrated circuits, semiconductors and electric vacuum devices. In processes such as epitaxy, lithography, cleaning and evaporation, high-purity nitrogen is used as a gas for replacement, drying, storage and transportation. In aerospace technology, liquid hydrogen filling systems must first be replaced with high-purity nitrogen and then with high-purity helium.

Nitrogen generally has three forms: solid, liquid, and gas.

Nitrogen, the chemical formula is N2, the molar mass of the nitrogen atom is 14g/mol, the relative molecular weight is 28, and the nitrogen percentage in atmosphere is 78%.

No. Nitrogen is chemically inactive, and can only react with hydrogen to form ammonia under high temperature, high pressure and catalyst conditions.

Nitrogen poisoning is a type of poisoning symptom caused by nitrogen. Nitrogen itself is non-toxic, but when the nitrogen content in the air is greater than 84% and the oxygen is less than 16%, it can lead to hypoxia asphyxiation. Patients may experience dizziness, chest tightness, rapid heart rate, shortness of breath, unconsciousness, or even coma, convulsions and other symptoms. Extremely high concentrations of nitrogen can cause sudden death.
