Air Liquide S.A., or Air Liquide , 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 second largest supplier of industrial gases by revenues and has operations in over 80 countries. It is headquartered in the 7th arrondissement of Paris, France. 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 , as well as in Houston, TX, and Newark, DE, USA. There is an emphasis on research and development throughout the entire 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 , combustion, membranes, modeling, and the production of Hydrogen gas.As of 2009, the company is ranked 484 in the Fortune Global 500.

A burner and/or injector panel apparatus includes a flange rotatable within a cylindrical aperture in a horizontal plate and securely retainable between one or more retaining clips and the plate. Extending downward from the flange is a main body with a cylindrical chamber. A burner, burner/injector, or injector is contained within the cylindrical chamber. The main body has a helical cooling circuit extending around the cylindrical chamber and burner and/or injector. The burner and/or injector panel apparatus may be installed through a furnace wall, especially an electric arc furnace, more particularly, a balcony panel of a sump area of an electric arc furnace. The burner and/or injector panel apparatus may be tilted from horizontal or rotated around its vertical axis in order to better target a target area of a molten bath of metal with a flame, jet of oxygen, or stream of carbon particles.

A method for condensing argon can include two flow streams interacting with each other in a heat exchanger found within a cold box: a stream of gaseous argon enters the heat exchanger to be cooled down below its liquefaction point by a stream of pressurized liquid nitrogen entering the heat exchanger. While passing through the heat exchanger, gaseous argon is gradually cooled down until it is condensed into liquid, flowing by gravity to the nearby liquid argon storage tank.

An apparatus for condensing argon can include cold box, which is preferably sealed and largely maintenance free, where all instruments and valves requiring routine maintenance are to be located outside, a nitrogen separator disposed within the cold box, a heat exchanger disposed within the cold box, the heat exchanger is configured to condense a gaseous argon stream against a pressurized liquid nitrogen stream. The cold box is elevated as compared to an argon storage vessel, such that the condensed argon stream can flow to the argon storage vessel without the need for a pump.

The apparatus for ethane liquefaction can include a mixed refrigerant refrigeration cycle having inline compression without interstage cooling, or cooling only after the first compression stages where there is no liquid formation yet, such that the number of liquid recycle loops are reduced. The lack of cooling in the compressor reduces the compressors mechanical efficiency; however, this is offset by having a more thermodynamically efficient process cycle because the cycle can operate as a mixed refrigerant rather than cascade.

The process for liquefying a gaseous stream received from a pipeline that is comprised predominantly of ethane and a relatively small amount of other components by using a mixed refrigerant loop incorporating heavy hydrocarbons, as well as a distillation column to remove constituents lighter than ethane.
