Providing innovative solutions to sustainably and safely increase performance, so you stay competitive.

Turn-key solutions

Air Liquide has extensive experience with world-class chemical companies that produce a range of products, such as ethylene, propylene, chlorine, ethylene oxide, acetic acid, polyesters, polycarbonates, and everything in between. To meet the diverse needs of the chemical industry, we supply gases in varying purity, volumes and supply modes. In addition, we offer production technologies, storage solutions and an extensive network of pipelines supplying large volumes of gas (primarily oxygen, nitrogen, hydrogen and syngas) as well as steam and demineralized water. Our range of products, technologies and services will help you operate safely, efficiently and in a sustainable way.

Turn-key solutions for large-scale chemical producers

Air Liquide offers an integrated value proposition for large-scale chemical manufacturers. Our over-the-fence and pipeline supply options for oxygen, nitrogen, hydrogen and syngas are central to our offer, in addition to gas calibration standards for analysis, process control and environmental compliance. We also supply a range of proprietary production and processing technologies. Air Liquide Global E&C Solutions – a technology partner of choice for the design, engineering and construction of leading-edge processing facilities and related infrastructures worldwide – offers a full suite of customizable solutions for the chemicals industry to help you optimize and integrate processes with smarter and efficient technologies.

Basic Chemicals

Our gases are used in various stages of converting basic chemicals and intermediates to make ethylene oxide, ethylene, chlorine, sodium hydroxide, vinyl chloride monomer and ethylene dichloride. We supply oxygen, hydrogen and carbon monoxide for use as chemical feedstocks. Additionally, we supply many calibration standards to help you identify impurities in materials before production begins and to aid in environmental compliance, including hydrocarbon gas and liquid standards, oxygenates and alcohol, liquid olefins and moisture, ammonia and sulfur. To ensure safety and purity, nitrogen is used throughout the entire process for inerting and blanketing.

Air Liquide Global E&C Solutions is a technology partner of choice for the design, engineering and construction of leading-edge gas production facilities and also specific processing facilities, including gasification, the proprietary Lurgi™  methanol process, as well as methanol to propylene.

Fine Chemicals

During this final stage of the value chain, our gas solutions are employed to turn intermediates such as styrene, polyols and bisphenol A into polystyrene, polyurethane and polycarbonate. Calibration standards are available to measure impurities in ethylene oxide production, and we also supply specialized liquid blending for custom applications. We supply oxygen, hydrogen and carbon dioxide for use as chemical feedstocks and other applications. To ensure safety and purity, nitrogen is used throughout entire process for inerting and blanketing.

Research and Quality Control

Research, testing and measurement teams must rely on a level of expertise equivalent to their own. Chemical manufacturers expect their suppliers to anticipate their needs and proactively develop smart solutions tailored to their research and processes. Airgas offers a complete range of calibration standards and carrier gases to aid regulatory compliance, analysis, and quality and process control, as well as gas handling equipment and related services. ALPHAGAZ™—our global brand of premium pure analytical gases—simplifies gas selection for any analytical application.
