Oxygen is used as an oxidation agent on raw chemicals for recovering ethylene oxide, propylene oxide, dichloride, hydrogen peroxide, nitric acid, vinyl chloride, etc.
It also finds application in the oil and gas industry for enhancing the viscosity and flow qualities of oil and gas. On the other hand, it is also used to increase the production capacity of oil crack plants. Besides, it is also finds applications in improving the efficiency of high-octane components processing. It is also applied for reducing the sulfuric deposits in refineries.
Other uses of oxygen in industries include enhancing the air feed to catalytic cracking regenerators, which significantly improves the capacity of units. It is also used in refineries for regenerating catalysts. And, it is used for achieving robust combustion and for elimination of harmful waste materials in incinerators.
The food industry has number of applications for liquid nitrogen. Firstly, it allows speedy freezing of food item and guards against cell damage because of ice crystals. It also improves the taste, texture and appearance of food items.
Numerous food items like vegetable oil and wines can be protected by the inert properties of nitrogen against loss of quality by oxidation by removal of any air contained in the liquids (sparging). It is also used for protecting liquids in storage tanks by filling vapor space (blanketing).
Nitrogen also finds applications in extending the shelf life of package foods by protecting against oxidation, mold, insect infestation and moisture migration. It is used, especially, in transport trucks and in Modified Atmosphere Packaging (MAP), however, it is nitrogen mixed with CO2 and oxygen.
Oxygen finds applications in wide range of industries. Glass industry is one of them where it is used for replacing combustion systems from air fuel to oxygen-fuel. As a result of application of oxygen, the control over heating patterns will improve besides enhancing efficiency of furnaces. And, it is also very useful for reducing particulate and NOx emissions.
For increasing burning temperature, the glass industry uses oxygen, which is also handy in increasing burning processes. It is one of the most abundantly found elements in the atmosphere and is used by living beings and is also extensively used across wide cross-section of industries.
Nitrogen finds many applications in numerous industries. It is used as a shield gas for protections of some medicines against oxidation or moisture absorption. Liquid nitrogen is used in cryo-surgery for destruction of malignant or damaged cells.
It is also used for freezing blood as well as viruses for vaccination. Then, it is also used in cryopreservation—freezing livestock semen which can then be stored for years. No denying the quick freezing as a result of acute cold lessens the probability of cell wall damage.
In the healthy industry, oxygen is also kept in stock. It is given to patients who have difficulty in breathing. Moreover, the breathing apparatus is also used by astronauts, scuba divers and mountaineers. Oxygen also finds application in the elimination of bacteria. It is even used treating victims of carbon monoxide poisoning.
Steel industry is known as the largest user of Oxygen. The steel industry is dependent on oxygen for increasing combustion temperatures in blast and open hearth furnaces. In the steel-making industry, unused carbon mixes with oxygen to form carbon oxides.
Oxygen is sent into the steel bath through a special incision. It allows greater usage of scrap metals in electric arc furnaces. On the other hand, numerous metals such as lead, zinc and copper are made using large volumes of oxygen.
Apart from oxygen, nitrogen is also used in the manufacturing of steel and other metals. It treats melt in the manufacturing process of steel and other metals. Moreover, it is also used as a shield gas in the heat treatment of metals like, steel, iron, etc.
In the oil and gas industry, oxygen is used for enhancing viscosity and oil-and-gas flow properties. It is also used for maximizing production capacity of cracking plants. It also used for reduction of sulfuric deposits in the refineries besides increasing the efficiency of high-octane components processing. Oxygen also finds extensive application in oxidation of raw chemicals for recovering ethylene oxide, nitric acid, propylene oxide, vinyl chloride and numerous other chemical compounds.
It is not just oxygen which finds applications in the oil and gas industry but nitrogen is also extensively used in refineries and petrochemical plants. Nitrogen is used for elimination of dangerous vapors and gases from the equipment besides being used as a protective sheath in tanks filled with flammable liquids.
In the pharmaceutical industry, liquid nitrogen plays a significant role as low temperatures enable better control of side-reactions of complex reactions. And low temperatures are achieved by using cooling reactors. It is because of liquid nitrogen that we can swiftly attain low temperatures and maintain them as well for cold reaction temperatures.
However, circulating low-temperature heat transfer fluid is used in reactor cooling and temperature control systems for delivering refrigeration generated by vaporizing liquid nitrogen to the reactor. Specially designed heat exchangers are used for vaporizing liquid nitrogen which are used for transferring refrigeration to the circulating heat transfer fluid.
In order to make steel and iron in blast furnaces, industries make use of hot oxygen, which is also used by mining companies to destroy rock formations. It is used largely in welding, cutting and grazing and metal processing. It can produce temperature in the range of 3000 C and 2800 C, which are required in oxy-hydrogen and oxy-acetylene blow torches used in welding. The gas is most commonly used in gas-flame operations like metal welding and cutting and brazing.
Oxygen has large number of application across various industries. Needless to say, it is used for manufacturing acids—sulfuric acid, nitric acid and numerous other compounds. Ozone, its most reactive variant, is used in numerous chemical reactions. Industries use oxygen to enhance reaction rate as well as for oxidation of unwanted compounds.
A high temperature flame is used to melt them by heating the junction. The ends are melted and solidify. To slice metal, one end is heated until it turns red. The oxygen level is augmented until the red hot component has oxidized. This softens the metal so it can be hammered apart.
