To alter the structure of feedstocks through oxidation,
producing nitric acid, ethylene oxide, propylene oxide,
vinyl chloride monomer and other building block chemicals;
and to increase capacity and destruction efficiency of
To enhance combustion in glass furnaces and forehearths,
reducing nitrogen oxide (NOx) emissions to levels below
new stringent requirements.
To resuscitate or, in combination with other gases, to
anaesthetise; but also essential to life-support systems
used in emergencies or long-term treatment of patients
with respiratory disorders.
To support oxyfuel cutting operations. Sometimes added
in small quantities for shielding gases.
To replace or enrich air, increasing combustion temperatures
in ferrous and non-ferrous metals production; to create
a hot flame in high-temperature welding torches used in
cutting and welding.
Recovery and refining to reduce viscosity and improve
flow in oil and gas wells; to increase capacity of fluid
catalytic cracking plants as well as to facilitate use
of heavier feedstocks; and to reduce sulphur emissions
||Pulp and paper
To help manufacturers meet stringent environmental regulations
in a variety of mill processes including delignification,
bleaching, oxidative extraction, chemical recovery, white/black
liquor oxidation and lime kiln enrichment.
To enrich air and increase combustion temperatures in
blast and open hearth furnaces; to raise steel temperatures
and enhance recycling of scrap metal in electric arc furnaces;
and to replace coke as the combustible in steel making.
Owing to its life-supporting nature, oxygen is used in
industrial and municipal water/wastewater treatment facilities.
Using 90 to 99 percent oxygen instead of air boosts the
biological activity required to eliminate wastes in water.
And, with a 90+ per cent utilisation rate, oxygen provides
an efficient and economical method.
