Industrial gas production and distribution

Industrial gas production and distribution has remained at the core of Air Liquide’s business since its founding in 1902. In the U.S., our robust production and distribution networks are engineered to serve the needs of our diverse customer base. Air Liquide owns and operates more than 140 industrial production facilities throughout the U.S.

Primary production facilities:

  • Air Separation Unit (ASU) – oxygen, nitrogen and argon

  • Cogeneration – electricity and steam

We deliver a range of industrial and specialty gases in bulk and in cylinders through a robust distribution network.

  • 700+ professional truck drivers
  • 500+ tractors and trailers
  • 60+ truck and rail depots

We deliver enormous volumes of oxygen, nitrogen, hydrogen and syngas to large industrial customers in Texas and Louisiana through extensive pipeline networks.

Air Liquide owns and operates more than 2,000 miles of industrial gas pipeline in the U.S.

Air Liquide has developed an array of on-site industrial gas production technologies to meet the needs of many industries. We install, operate and maintain a range of on-site production systems, which generate medium to large volumes of oxygen, nitrogen and hydrogen at hundreds of customer sites.
