Technical oxygen


Technical standards for gaseous oxygen - ISO 2046-73.

Formula - O2.

The molecular weight (on the international nuclear weights of 1985) - 31.9988.

The mass concentration of solids in the medical oxygen - no more than 0.001 g / m3 with a particle size of not more than 0.1 mm at 15 ° C and 101 3 kPa (760 mm Hg. V.).

This is the most versatile product that is used in many industrial processes in welding and cutting metals, medicine and even food industry, it provides a process of oxidation and burning, respectively. Oxygen should be protected from the sun indoors and away from heating appliances. In the application it is necessary to avoid contact with materials containing oil, since there is a danger of spontaneous combustion.

Technical oxygen, both gaseous and liquid, is procured under specification BB-0-925. The moisture content of technical oxygen is not as rigidly controlled as that of breathing oxygen; therefore, the technical grade should never be used in aircraft oxygen systems.

Once converted into a liquid, oxygen will remain in its liquid state as long as the temperature is maintained below  – 297 ‘F. The liquid has an expansion ratio of 862 to 1, which means that one volume of liquid oxygen will expand 862 times when converted to a gas at atmospheric pressure. Thus, 1 liter of liquid oxygen produces 862 liters of gaseous oxygen.


Oxygen is required in the preparation of synthetic liquid fuels, lubricants, nitric and sulfuric acid, methanol, ammonia and ammoniacal fertilizers, peroxides, metals and others.

The high efficiency of oxygen utilization in industry was the impetus for the development of air separation. Metallurgy currently is the major consumer of oxygen in the industry with oxygen-related development of  converter steelmaking.

Oxygen is used in the processes of:

  •     Production of iron and steel (removal of excess carbon).
  •     BOF steel production.
  •     Electric steelmaking.
  •     Oxygen blast in blast furnaces.
  •     Ferroalloy production.
  •     Melting nickel, zinc, lead, zirconium, and other nonferrous metals.
  •     Intensification of firing the raw material in non-ferrous metallurgy.

Chemical and Petrochemical Industry

Electrochemical processes are based on oxidation-reduction and widely used in various fields of modern techniques in analytical chemistry and biochemistry.

Oxygen is required in the preparation of synthetic liquid fuels, lubricants, nitric and sulfuric acid, methanol, ammonia and ammoniacal fertilizers, peroxides, metals and others. Chemical products. In the oil and gas industry is used to more efficiently refineries - to increase the productivity of plants for petroleum cracking.

Oxygen is necessary for the gasification of solid fuels, compression-coal mixture firmly and to enrich air for industrial boilers.

In construction and engineering

Oxygen is necessary for plasma metal cutting and soldering, spraying and welding metals.

Pure oxygen is consumed mainly in the production of steel and iron scrap.

Glass industry

Oxygen is essential in the glass-blowing, factories medical and laboratory glass in the manufacture of light bulbs.


  • ozonation water treatment, waste water treatment, pulp bleaching and so on,
  • waste disposal - with neutralization (oxidation) reactive waste incinerators with oxygen dutёm,
  • metal recycling.

Oxygen is used in fish farms to increase the survival rate and yield offspring for growing fish, crabs, shrimp, mussels.

Oxygen is supplied in pressurized cylinders: blue, 150 atmospheres in the compressed form. In industrial area can be transported through special pipes.
