|
Chemical processing
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
waste incinerators. |
|
|
Glass manufacturing
To enhance combustion in glass furnaces and forehearths,
reducing nitrogen oxide (NOx) emissions to levels below
new stringent requirements. |
|
|
Health services
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. |
|
|
Metal fabrication
To support oxyfuel cutting operations. Sometimes added
in small quantities for shielding gases. |
|
|
Metal production
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. |
|
|
Refining
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
in refineries. |
|
|
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. |
|
|
Steel manufacturing
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. |
|
|
Water/wastewater treatment
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. |
