Aquaculture – Fish FarmingIn recent years, fish farming has turned into high density farming practice using ponds, large scale tanks etc. Oxygen is essential in all modern fish farming. Fish need oxygen to live and grow, when fish grow the density of fish in the ponds increases, while the oxygen saturation level in the water decreases and the loss of fish will be high.
Glass ManufacturingOxygen in glass industry plays very important role and is typically used to enhance combustion. The benefits are fuel saving due to improved furnace efficiency, increased flame temperature, reduced energy cost, reduced pollutants, improved glass quality and etc. These benefits create an platform for production increase which is the most common motivation for using oxygen.
Gold MiningAdding oxygen to the air in the gas desulfurizing process results in a number of benefits, e.g. increased plant capacity, more flexibility, and improved conversion of ammonia. By using oxygen to convert mineral sulphides to sulphates and processing them, gold yield can be more than doubled over standard ore gravity separation and concentration. By sparging 94-95% oxygen into a thickened flotation concentrate (which has been heated under pressure) an oxidized slurry results. Not only are sulphides converted to sulphates by the O2, but arsenic is converted to ferric arsenate.
MedicalBeside basic respiratory support, benefits of medical oxygen can make feeling of well-being and freshness, increase partial pressure of oxygen in blood, muscles and muscle tissue, improve levels of concentration as well. Normally, oxygen supply of healthcare including central oxygen supply to hospitals, nursery & retirement homes, field hospitals, veterinary facility.
MetallurgyOxygen gas is used in shaft furnaces melting lead, tin, zinc, copper and rock wool. The most important benefit is the increase of output with a simultaneous coke reduction. Meanwhile, in the waste disposal and recycling industry, the use of pure oxygen in various high-temperature operations increases the process efficiency, saves energy and lowers pollutant emissions.
Metal Brazing & CuttingPure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material. A common propane/air flame burns at about 2,250 K (1,980 °C; 3,590 °F), a propane/oxygen flame burns at about 2,526 K (2,253 °C; 4,087 °F).
Ozone GenerationOxygen (O2) and Ozone (O3) are gaining wide acceptance in water treatment. There has been rapid development in both the methods of reliably producing low cost oxygen and ozone and applying them to water treatment problems.
Pulp & Paper ManufacturingOxygen is increasingly important as a bleaching chemical. In the manufacture of high-quality bleached pulp, the lignin in the pulp must be removed in a bleaching process. Chlorine has been used for this purpose but new processes using oxygen reduce water pollution. Oxygen plus caustic soda can replace hypochlorite and chlorine dioxide in the bleaching process, resulting in lower costs.
VeterinariansAs an essential veterinary facility, the central oxygen supply system is designed with monitoring features allowing backup and the ability to trigger immediate restoration in the unlikely event of a system failure.
Water TreatmentThere has been rapid development in both the methods of reliably producing low cost oxygen and ozone and applying them to wastewater treatment problems.
