Product Applications

 

Chemicals   Oxygen can be used as a chemical reactant and in combustion systems. Benefits
over air include increased reaction rates, yield improvements, reduced capital cost
of new plants and reduced air emissions.
Food   Oxygen can be used in fermentation to maintain an aerobic state.
Fish Farms   Higher levels of dissolved oxygen, resulting from the use of oxygen instead of air,
allow more fish to be grown and remain healthy in a given volume of water.
Lasers   Oxygen can be used as an assist gas for the cutting of mild steel and stainless steel.
Medical   Breathing oxygen instead of air allows greater oxygenation of the blood stream in
situations of impaired breathing action and lung function.
Metals   Oxygen enrichment is frequently employed in iron, copper and lead blast furnaces,
iron melting foundry cupolas and rock or slag-melting cupolas to increase productivity
and reduce the specific coke consumption.
Water Treatment   Oxygen can be used in place of air in the activated sludge process to maintain a
higher population of micro-organisms. Using oxygen injected through a side stream
instead of using a mechanical aerator eliminates surface agitation, reducing odour.
Injecting oxygen into pumped sewer mains maintains the sewage in an aerobic state,
preventing formation of hydrogen sulphide.
