Oxygen is the most abundant element on the earth’s surface, it represents by weight 46% of the Earth's crust, 89% of the Earth's water, 21% of the air we breathe, 62% of the human body.

Oxygen  is a tasteless, odorless and colorless gas essential to life. It can combine with all the other elements (except rare gases) in order to oxidize them and consequently produce energy. Oxygen is used in many industrial applications because is an oxidizing agent (combustive, oxidant).


For Oil & Gas, Metals, Mining, Chemicals industries, Air Liquide Canada provides oxygen in large quantity to increase efficiency in a number of processes by reducing the amount of fuel used and decreasing carbon dioxide emissions.

Below we present you a few of the numerous applications of oxygen for different industries.
