On-Site Production

Fully integrated systems

Air Liquide supplies a range of customizable on-site production solutions to meet the diverse needs of many industries with regard to volume and purity.


A tailored supply system

Air Liquide will help you minimize costs with an optimally-designed supply system that meets your unique gas usage profile. Air Liquide will identify the optimal supply solution for your facility by determining accurate usage patterns of the gas and evaluating opportunities to optimize gas consumption. We also take your growth potential and the impact of future gas requirements into consideration to identify potential cost savings.


  • Continuous, reliable gas supply of consistent quality
  • Flexible modular design for easy upgrading when necessary
  • Load following of gas demand minimizes energy costs
  • Guaranteed performance – energy and flow rate
  • Performance-tracking telemonitoring supported by a network of alarm response centers and qualified service technicians
  • Backup system helps ensure uninterrupted gas supply
  • Carbon footprint is significantly reduced compared to delivered gases

Large-scale on-site production

Large-scale on-site units (tonnage)

We have the capacity to invest, design, build and operate large-scale production plants for large industrial customers like chemical producers and refineries. 

Air separation units (ASU) compress, liquefy and distill air to separate it into its various components: nitrogen, oxygen, and rare gases (argon, neon, krypton and xenon).

Steam methane reformers (SMR) produce hydrogen and carbon monoxide through steam reforming. Hydrogen is typically used in the oil- refining process for hydrodesulphurization and to convert heavy crude oil into cleaner burning transportation fuels.

Our air separation units and steam methane reformers are designed and built using the Group’s latest technologies, providing both high reliability and energy efficiencies.

Cogeneration consists of simultaneously and efficiently producing electricity and steam, generally by consuming natural gas and water. The electricity is typically supplied to the local network while the steam is required for certain industrial processes. Cogeneration is an environmentally virtuous process, since it avoids energy losses by harnessing the heat emitted during electricity production to produce steam.

On-site industrial gas generators (bulk volumes)

Air Liquide supplies industrial gas generators that supply bulk volumes of industrial gases like nitrogen, oxygen and hydrogen generators to a range of industries. Our on-site nitrogen and hydrogen production systems help ensure continuous, reliable supply as demand fluctuates. Air Liquide installs, operates and maintains on-site supply systems. Our goal is to ensure a continuous and reliable gas supply so you can focus on your business.

Air Liquide supplies a range of on-site nitrogen generation technologies:

On-site hydrogen generation technologies:

Air Liquide’s hydrogen generation system offers a low-cost, reliable, efficient, and flexible solution for producing high-purity gaseous hydrogen or liquid hydrogen on-site at your facility.
