Air gases are at the core of the global industrial gases business. To use a sporting analogy, they’re the first names on the team sheet – oxygen, nitrogen and argon as the spine of the team.
The production processes behind these gases are based on a technology that is itself now well over 100 years old and yet continues to be improved in terms of efficiency, cost, reliability, and size. The air separation unit (ASU) has come a long way since it was first pioneered over a century ago; these huge feats of engineering are emerging around the world all of the time, in various configurations and ever-increasing capacities.
This year alone has seen numerous significant ASU projects either completed or announced in a number of regional markets as the industry strives to install gas production hubs as close to the demand centres as possible.
