Oxygen is a colorless, odorless and tasteless gas that supports life and combustion. All elements, except rare gases, react with oxygen, over a wide range of temperatures, to form oxides. Oxygen is 1.1 times heavier than air and is slightly soluble in water.Oxygen is present in the atmosphere at a concentration of 21.0%. Oxygen is recovered from air in an Air Separation Unit (ASU) where it is drawn off as a cryogenic liquid at about -298°F. Oxygen can then be distributed as a cryogenic liquid or as a gas in cylinders. Oxygen can also be generated onsite, using various techniques.
