The use of oxygen in gas-flame operations, such as metal welding, cutting and brazing is one of the most significant and common applications of this gas. Oxygen allows generating high-temperature flame in welding torches thus ensuring high quality and speed of work performance.

Oxygen is heavily used in the metal industry where it helps to increase burning temperature by the production of ferrous and non-ferrous metals and significantly improve the overall process efficiency. Another important oxygen application in the metal industry is connected with its use for carbon fixation with the yield of carbon dioxide.

In the chemical and petrochemical industries, oxygen is widely used for oxidation of raw chemicals for recovery of nitric acid, ethylene oxide, propylene oxide, vinyl chloride and other important chemical compounds.

In the oil and gas industry, oxygen finds application as a means for viscosity improvement and enhancement of oil-and-gas flow properties. Oxygen is also used for boosting production capacity of oil cracking plants, efficiency of high-octane components processing, as well as for the reduction of sulfuric deposits in refineries.

The use of oxygen in the fish farming helps increase the survival and fertility ratios and reduce the incubation period. Along with fish culture, oxygen is applied for shrimps, crabs and mussels rearing.

In glass furnaces oxygen is effectively used for burning temperature increase and burning processes improvement.
