Largest ASU anchors Air Liquide’s position in Eastern Europe


After the recent announcement of the Air Liquide Severstal joint venture to launch the world’s largest ASU in Russia, gasworld decided to follow up this news with an exclusive chat with the forces behind the project.

Situated at the Cherepovets steel complex in the Vologda region between Moscow and St Petersburg, the world’s biggest oxygen production unit will help Russian steel giant Severstal improve its energy efficiency while also expanding Air Liquide’s presence in Eastern Europe.

With a daily production capacity of 3,000 tonnes of oxygen it is the biggest gas unit in Russia and the largest air separation unit in the world dedicated to the steel industry.
