Being a supporter for life, Oxygen is used in different areas of industry due to its reactive character. The first way oxygen is used commercially is for enlightening stages. Since the beginning of the century, it has been used for welding and in medicine. It is consumed intensely in steel production after 1950s.
Oxygen is used for energy optimization in the production of iron and steel to fasten the melting. Also, oxidation is used in several different industry applications. It provides the needed source of heat in welding, cutting and metal processing when mixed with flammable gases. In metal production facilities other than iron, in rotating furnaces, in paper factories and on the production of glass when it's used in a furnace or burner, the use of oxygen reduces the amount of burned by-products that cause pollution.

NITROGEN
Nitrogen, as constituting 78% of the atmosphere, is a widely used gas in several industries with its two main features. Nitrogen is inert to several different materials and is very cold when liquid. These features qualify nitrogen as an indispensable and safe freezer and cooler. Under normal circumstances, it does not get involved in chemical reactions. Several reactions including combustion reactions can be prevented in a nitrogen atmosphere. As a result of the advancements in technology, nitrogen became a valuable industrial gas and is widely used even though its value is recently discovered.
