Gaseous nitrogen for creation of the inert atmosphere on production

Nitrogen - gas without color, a smell and taste, we will badly dissolve in water. Density of gaseous nitrogen of 1,25046 kg/m3 at 0 °C and pressure of 101,3 kPa, specific volume is equal to 860,4 dm3/kg with a pressure about 105 Pas and temperature 290 K. Liquid nitrogen - flavourless colourless liquid with a temperature of boiling of which makes 77,35 K with a pressure of 101,3 kPa and with a specific capacity of 1,239 dm3/kg at a temperature of 77,35 To and pressure of 101,3 kPa. It is harmless to environment, is nontoxical though breath in the environment with the content of oxygen less than 19% about. poses hazard to life. The word "nitrogen" from Greek "azoos", is translated as "lifeless".

Nitrogen gaseous and liquid is received from atmospheric air. Ways of its receiving known for today: membrane, the adsorptive and cryogenic.

Gaseous nitrogen is used for creation of the inert atmosphere by production, storage and transportation of easily oxidized products, at high-temperature processing of the metals which are not interacting with nitrogen, for preservation of the closed metal vessels and pipelines, for other purposes. Liquid nitrogen is used as the refrigerating agent.

Production of the enterprise has the certificate of origin (nitrogen liquid) CT KZ № KZ 2 09 00205.
