O2-liquid Oxygen
Oxygen (O2) is a colorless and odorless gas and is the third most abundant element in the universe by mass. All living things depend on oxygen in some form. Oxygen is obtained on a commercial scale through liquifaction and distillation of ambient air. A second purification process may be necessary if ultra-high purity levels are required. The main industrial application of oxygen is combustion. Many materials that do not normally burn in air will burn in oxygen. Mixing oxygen with air greatly enhances combustion efficiency in iron, steel, glass and concrete industries. Oxygen is available in liquid and gaseous forms.
