Linde plc is a global multinational chemical company founded in Germany and, since 2018, domiciled in Ireland and headquartered in the United Kingdom. Linde is the world's largest industrial gas company by market share and revenue. It serves customers in the healthcare, petroleum refining, manufacturing, food, beverage carbonation, fiber-optics, steel making, aerospace, material handling equipment (MHE), chemicals, electronics and water treatment industries.[1] The company's primary business is the manufacturing and distribution of atmospheric gases, including oxygen, nitrogen, argon, rare gases, and process gases, including carbon dioxide, helium, hydrogen, ammonia, electronic gases, specialty gases, and acetylene.[1]
The company was formed by the 2018 merger of Linde AG of Germany (founded in 1879) and Praxair (founded in 1907 as Linde Air Products Company) of the United States. The resulting holding company was incorporated in Ireland, with principal executive offices in Woking, UK.[3]
In the industrial gas area, the company uses the brand names Linde, AGA, BOC, TIG, Mox-Linde Gases, Afrox, Sigas and PanGas. HiQ is used as an identifier for high purity and premium specialty gases across all of these business brand names.
In the medical gas area, the company uses the brand names Linde Gas Therapeutics, AGA Medical, INO Therapeutics, Linde Homecare, and Farmadomo.
Linde Gas supplies industrial gases, medical gases, specialty gases, refrigerants and other chemicals. Depending on the gas and the quantity required, these may be supplied in portable high-pressure gas cylinders, in liquefied form by road tanker, from on-site gas generators or in gaseous form via pipeline to large customers. This division has four operating segments, Western Europe, the Americas, Asia & Eastern Europe, and South Pacific & Africa. These segments are subdivided into eight Regional Business Units (RBUs). The Gases Division also includes the two Global Business Units (GBUs) – Healthcare (medical gases) and Tonnage (on-site) – and the two Business Areas (BAs) – Merchant & Packaged Gases (liquefied and cylinder gases) and Electronics (electronic gases).
The product range includes hydrogen, acetylene, carbon monoxide, carbon dioxide, shielding gases for welding applications, noble gases and specialty gases, oxygen, nitrogen, and argon, all of which are manufactured in Linde's air separation plants.
Uranium used to produce the United States' first atom bombs from 1942 to 1948 was processed by Linde Air Products in Tonawanda, New York. This company originally had been founded as U.S. branch of the German “Gesellschaft für Linde´s Eismaschinen Aktiengesellschaft” in 1907, but had been expropriated in 1917 and was integrated into Union Carbide & Carbon Corporation. The New York Times reported in 1981 that 37million U.S. gallons (140million liters) of radioactive caustic wastes from the Manhattan Project was dumped into nearby shallow wells specifically chosen "to hide the source of the contamination". Active remediation of sites in Tonawanda was completed in 2013 and have been in a long-term surveillance and maintenance since 2017.
On 21 June 1879, Carl von Linde founded the Gesellschaft für Linde's Eismaschinen Aktiengesellschaft to develop further his work in developing mechanical refrigeration systems for the brewing and food industries. Following success in this market, he moved on to developing lower temperature systems resulting in 1895 in a patent covering the liquefaction of air. Out of this work his company developed equipment for the separation of air and other gases. Linde's process was patented in 1902 and immediately exploited by the first large-scale air separation plant installed in Linde's works in Höllriegelskreuth, near Munich in 1903.[11]:67
In 1906, Carl Von Linde decided to expand his oxygen extraction company overseas, targeting America, where no other companies had attempted industrial scale oxygen extraction. Along with Cecil Lightfoot, in 1907, he opened the Linde Air Products Factory, his first plant in America at Buffalo, New York.[14][15]
In addition to plants for air separation, in 1906, Linde engineers started working with others on processes to separate the constituents of water gas.[15] This work lead to the 1909 invention of the Linde–Frank–Caro process to produce hydrogen and carbon monoxide, which were further key feedstocks for the emerging chemicals industry.
In addition to his interests in refrigeration, Carl von Linde had also partnered with Hugo Güldner and Georg Krauß and others in 1904 to form the Güldner Motoren-Gesellschaft mbH in Munich, which was moved to Aschaffenburg in 1906. Linde took full ownership of the company in 1929, and from this origin developed a business manufacturing first engines and tractors, and then from the 1950s onwards, a range of mechanical handling equipment such as fork lift trucks. Linde also acquired the Aktiengesellschaft für Industriegasverwertung (english: Corporation for Industry Gas Utilization), commonly referred to as the Heylandt Works.
Following World War I, Linde's U.S. assets were confiscated. They were incorporated into the Union Carbide Corporation (UCC) as the Linde Air Products division in 1917.[16] Eventually, in 1992, this part of Union Carbide was spun off as Union Carbide Industrial Gases Inc., and renamed Praxair. In 2018 this became part of Linde when Linde merged with Praxair.
In the years of Nazi Germany, Linde AG benefited from the country's attempt to become self-sufficient by refraining from imports of synthetic fuel and rubber. In 1935, general manager Friedrich Linde received the title of Wehrwirtschaftsführer, which underlined the national importance of Linde AG and allowed the company to further benefit from the German rearmament.[11]:99
Before and during World War II, all departments of Linde AG were in some way involved in the armaments production: The Heylandt-Gesellschaft für Apparatebau supplied the German rocket program, other branches produced welding equipment and engines for the armaments industry.[11]:111 In 1941, Linde manufactured oxygen and helium installations for IG Farben at the Auschwitz concentration camp. Three further planned installations were not installed due to the course of war.[11]:113–114 According to estimates of the company for mid-1944, between 400 and 500 people were used as forced labourers in production plants.[11]:115 The company claimed that 75% of its production facilities were destroyed during the war.[11]:126

Liquefaction of gases is physical conversion of a gas into a liquid state (condensation). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures, using, for example, turboexpanders.
Industrial gases are the gaseous materials that are manufactured for use in industry. The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders. The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases. Their production is a part of the wider chemical Industry.
