Air Liquide S.A. (French pronunciation: ​[ɛʁ likid]; /ˌɛər lɪˈkd/; literally "liquid air"), is a French multinational company which supplies industrial gases and services to various industries including medical, chemical and electronic manufacturers. Founded in 1902, it is the world's largest supplier of industrial gases by revenues and has operations in over 80 countries.[1] It is headquartered in the 7th arrondissement of Paris, France.[2] Air Liquide owned the patent for Aqua-Lung until it time-expired.

Although Air Liquide's headquarters are located in Paris, France, it also has a major site in Japan (ALL), as well as in Houston, TX, and Newark, DE, USA. There is an emphasis on research and development (R&D) throughout the Air Liquide company. R&D targets the creation of not only industrial gases, but also gases that are used in products such as healthcare items, electronic chips, foods and chemicals. The major R&D groups within Air Liquide focus on analysis, bioresources (foods and chemicals), combustion, membranes, modeling, and the production of Hydrogen (H2) gas.

The company is a component of the Euro Stoxx 50 stock market index.[3] As of 2009, the company is ranked 484 in the Fortune Global 500.[4]

Corporate structure[edit]

Board of Directors[edit]

Comprised as follows as of February 2017:[16]


Air Liquide Global E&C Solutions Germany GmbH (formerly Lurgi GmbH)[edit]

A German engineering, construction and chemical process licensing company. The head office is located in Frankfurt am Main. Air Liquide Global E&C Solutions GmbH (formerly Lurgi GmbH) has been part of Air Liquide S. A. since 2007. Lurgi was the cable address of Metallurgische Gesellschaft founded on 5 February 1897. Its origin dates back to the technical branch of Metallgesellschaft, which had been established by Wilhelm Merton in 1881. By the end of World War I, the company had gained a foothold in the steam and absorption business and gathered expertise in the upgrading of solid fuels and the processing of the resulting gaseous and liquid products. As a consequence of this diversification, the company divided into process-specific subsidiaries, which from 1919 traded under the name of LURGI. In 1923, they jointly moved into offices at Gervinusstrasse, Frankfurt am Main. In order to meet the requirements of the international markets, Lurgi constituted itself as a German stock corporation in 1990. Its operating limited liability companies - chemistry, metallurgy and industry construction; energy and environmental techniques; gas- and mineral oil techniques – each had their own engineering and commercial staff. In 1991, Lurgi pooled its polymer activities by taking over Zimmer AG from the British Davy-McKee AG as the fourth operating company. In 2001 Lurgi sold their metallurgical division (Lurgi Metallurgie) to Outokumpu. After acquisition into the Air Liquide company, the Zimmer technology portfolio was sold in end of 2014 to Technip.[17]

Air Liquide Global E&C Solutions Germany today focuses on three primary technology portfolios:

  • Alternative Technology based upon turning natural gas, coal, biomass to synthetic fuels through gasification, fischer-tropsch and proprietary methanol to synthetic fuels
  • Refinery Technology consisting of conventional refinery technologies.
  • Renewable Technologies including biodiesel as well as bioethanol processes.
