Linde plc

Linde plc is an Irish public limited company with main offices in the United Kingdom and United States. Linde is the largest industrial gas company globally and a significant technological innovator in the industrial gases industry. Its core industrial gases products include atmospheric gases (oxygen, nitrogen, argon, and rare gases) and process gases (hydrogen, helium, carbon dioxide, carbon monoxide, electronic gases, specialty gases, and acetylene). The company also designs and constructs equipment for industrial gas production and provides various gas production and processing services, such as olefin plants, natural gas plants, air separation plants, hydrogen and synthesis gas plants, and other plant types. Linde serves diverse sectors including healthcare, chemicals and energy, manufacturing, metals and mining, food and beverage, and electronics. Linde's sales were $33,986 million in 2025, $33,005 million in 2024, and $32,854 million in 2023. Atmospheric gases are Linde's highest volume products, produced from ambient air primarily through cryogenic air separation, and also using non-cryogenic air separation technologies, where Linde is a market leader. This process also yields rare gases like krypton, neon, and xenon. Linde develops proprietary and patented technologies for producing, storing, distributing, and increasing the use of its gases, including vacuum pressure swing adsorption ("VPSA") and membrane separation technology for on-site gaseous oxygen and nitrogen production. Process gases, such as hydrogen, helium, carbon dioxide, carbon monoxide, specialty gases, and acetylene, are produced using other methods.
