BOC Gasses
Industrial Gases
You will need to set up an account with BOC before we can supply you with theese gasses.
Air
Air constitutes of nitrogen 78%, oxygen 21% and argon 1%.
Argon is a noble gas. Krypton, neon and xenon are other noble gases and together they constitute less than 0,1 percent of the atmosphere.
Acetylene
Acetylene is a highly flammable gas. An acetylene/oxygen flame have a temperature over 3000°C. Acetylene is conventionally produced through a reaction between calcium carbide and water.
Carbon dioxide
Carbon dioxide (CO2), is a part of the life cycle in the nature. The gas is exhaled by humans and animals, and used by plants, that in return release oxygen. Carbon dioxide is produced from by-products from processes such as combustion, fermentation or oxidation of a carbon compound. The "raw gas" must be purifed in several stages to the quality required.
Helium
Helium is the second lightest element and the one with the lowest boiling point, -268,9°C. Helium is recovered most cost-effectively from natural gas.
