Pure nitrogen gas is colorless, odorless, non-toxic, non-flammable and non-reactive. Such gases are called inert. Inhalation of this gas in high concentrations replaces oxygen and causes suffocation. The density of inert nitrogen gas is lower than air.Types of nitrogen gas purity
Nitrogen gas can be supplied with different purities and customers can choose among them depending on their needs:
Industrial nitrogen with a purity of about 99.99%
Grade 5 nitrogen with 99.999% purity
Grade 5.5 nitrogen with 99.9995% purity
Grade 6 nitrogen with 99.9999% purity
It can be said that there are many uses of nitrogen gas in daily life. Basically, this gas is used in large quantities in the chemical industry to cover, clean and transfer the pressure of flammable chemicals. High purity nitrogen is used in large volumes by the semiconductor industry as a pure or carrier gas and also for cladding equipment such as furnaces during production. Nitrogen gas is used as carrier gas in gas chromatography. Pure nitrogen inert gas is used as zero or zero gas for analytical instruments or analysis. N gas is usually used as a balancing gas in gas mixtures. This gas is used in the electronics industry to infiltrate epitaxial reactorsPure nitrogen gas or a mixture of nitrogen with carbon dioxide is used for modified environmental packaging (MAP) of food. Also, nitrogen is used in the Haber-Bosch process to produce ammonia, and this gas is also used to fill tires to reduce wear and limit the risk of impact.The largest source of nitrogen gas production is separation from air through fractional distillation of liquid air. To increase the purity of this gas separated from the air, it must be re-purified. Also, nitrogen is produced and purified from PSA technology. Different methods are used to produce this gas except PSA absorption method. In the PSA method, compressed and dry air enters porous filters and separation is done through the difference in molecular size. Membrane methods can also perform separation, but are not common due to the high price and lack of affordability.Nitrogen itself is not a dangerous gas and does not cause problems due to its inertness. Even this gas mixed with oxygen is used as a breathing gas for diving at a shallow depth. Of course, at great depth due to the high pressure, it has anesthetic properties and causes the diver to feel sleepy, and it should not be used in this case. Although nitrogen is safe, the compounds that are made from it are known as nitrates and nitrites, which are carcinogenic substances that also make it difficult for oxygen to pass through the blood.Nitrogen is usually supplied in capsules with a capacity of 2, 5, 10, 20, 40 and 50 liters at a pressure of 150 to 200 bar. The standard color for the body of nitrogen capsules is gray color with a black throat. Zagros Air Liquid Company is an importer of high purity gas capsules. One of these gas capsules is high purity nitrogen gas. We have been able to produce and sell high purity nitrogen gas capsules with good quality and reasonable price. It should be noted that Zagros Air Liquid Company sells accessories for nitrogen gas capsules, including nitrogen gas regulators, at reasonable prices.
