Our solutions
Air Gases
A wide range of standard and customized air separation units and cryogenic liquefaction technologies to safely and efficiently deliver the essential industrial gases our customers need.
Comprehensive solutions for air separation and industrial gases
Air separation to deliver the industrial gases that our customers need is at the heart of our business and is a fundamental part of our history. We have the experience, flexibility and capacity to provide a wide range of air separation units through standard plants, customized offerings and other cryogenic liquefaction technologies. These systems are powered by our highly reliable proprietary equipment, including our Turboexpanders, which ensure optimal cooling and efficiency.
Our strength lies in our ability to adapt our plants' performances, safety, and construction design to each project and customer's needs.
Frequently Asked Questions (FAQ)
What is the difference between a custom-built ASU and a standardized plant?
Custom ASUs (Large ASU) are designed from the ground up for massive, multi-train industrial complexes. Standardized plants (Yango™ and SIGMA) utilize pre-engineered modules to drastically compress engineering schedules, reduce CAPEX, and accelerate fast-track site commissioning.
How does Air Liquide minimize the carbon footprint of air separation?
We continuously strive to improve the energy efficiency of our ASU portfolio. For example, our recent investment in an ASU in Uttar Pradesh, India, has been designed to operate fully on renewable energy by 2030, making a positive contribution to the energy transition.
Are your rare gas recovery systems standalone or integrated?
We produce these gases through units that are integrated with existing air separation units or as a standalone facility, delivered as assembled packages or on skid units to ease their installation.
