Industry

Air Liquide supports its industrial customers by offering its expertise and its cutting edge technologies so they can maintain the advantage in their field. For instance, we helped build the world’s largest helium liquefaction plant in Qatar, link the longest superconducting cable to the power grid in the United States, and design the first connected gas cabinet.

Microelectronics, requiring extreme purity, tolerate less than 1 ppb of impurity (0.0000001%) in its process and carrier gases. For this industry, ULTRALTM, Air Liquide’s line of cryogenic purifiers, has been designed to purify helium, hydrogen, nitrogen or argon by reversible cryogenic trapping on a high performance adsorbent bed.
