Oxygen (O2) is a colourless and odourless gas. It is vital for most life forms on earth.
The main industrial application of oxygen is combustion, which is applied in melting & heating, cutting & welding,… Oxygen is essential in hospital and medical clinic for medical treatment. It is also used in water treatment and aquaculture.
Oxygen is obtained on a commercial scale through the liquefaction and distillation of ambient air at air separation plants. A second purification process may be necessary if ultra-high purity levels are required. High-purity oxygen can also be produced through the electrolysis of water. Membrane techniques are suited to lower-purity requirements. Oxygen produced by Linde Vietnam’s Air Separation Plants reaches extremely high purity and directly supplied to customers through pipeline system or delivery fleet for various customer demand from 10 Nm3/hr to more than 1,000 Nm3/hr. Medical oxygen produced by Linde Gas Vietnam is certified by the Department of Health for Medical oxygen production and business.

Main applications of Oxygen:
The main industrial application of oxygen is combustion. Many materials that do not normally burn in air will burn in oxygen so mixing oxygen with air greatly enhances combustion efficiency in iron and steel, non-ferrous, glass and concrete industries. It is widely combined with a fuel gas for cutting, welding, brazing and glass blowing, offering much higher flame temperatures and thus greater efficiency than just air. With oxyfuel, plasma and laser processes, a jet of gaseous oxygen is used to cut steel. Oxygen is also popular in thermal lancing to drill or cut through materials such as concrete, brick, stone and various metals. Linde has decades of experience and a proven track record for gas-enabled applications in Melting and Heating.
Due to its ability to help stabilize the arc and reduce surface tension, oxygen is used as an ingredient in some shielding gas mixtures. The chemical industry relies on pure oxygen to increase the efficiency of oxidation reactions, for instance. High-purity oxygen is used in laboratories, process-control operations, gas-cooled nuclear reactors, metal analysis instruments, and in semiconductor and optical fiber production.
On the water treatment front, oxygen is an effective way of purifying wastewater and treating sewage. Other applications include sealing glass ampoules in the pharmaceutical industry, oxygenation of water for aquaculture, modified atmosphere packaging (MAP) mixtures and liquid explosives.
