Bulk Gases We are supplying a range of bulk gases including carbon dioxide, hydrogen, argon, nitrogen and oxygen. On-site gas supply solutions are also offered for nitrogen, hydrogen and oxygen.

Oxygen, nitrogen and argon are recovered from air by separation. It is a cryogenic method developed by Carl von Linde more than 100 years ago. The air is cleaned from solid particles, compressed where after water and carbon dioxide is separated. The gas is then cooled down to a very low temperature by expansion which will liquify the gas. The liquid is then separated by distillation into oxygen, nitrogen and argon and other rare gases.
