Acetylene is the chemical compound with the formula C2H2 and structure H−C≡C−H. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.
An inert gas is a gas that does not readily undergo chemical reactions with other chemical substances and therefore does not readily form chemical compounds. The noble gases often do not react with many substances and were historically referred to as the inert gases. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. These undesirable chemical reactions are often oxidation and hydrolysis reactions with the oxygen and moisture in air. The term inert gas is context-dependent because several of the noble gases can be made to react under certain conditions.
ESAB, Elektriska Svetsnings-Aktiebolaget, is an American-Swedish industrial company.
A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
The Hanshin Industrial Region is one of the largest industrial regions in Japan. Its name comes from the on-reading of the kanji used to abbreviate the names of Osaka (大阪) and Kobe (神戸), the two largest cities in the megalopolis. The GDP of this area is $341 billion, one of the world's most productive regions. 2014 Osaka and Kobe's GDP per capita (PPP) was US$35,902.
An oxygen concentrator is a device that concentrates the oxygen from a gas supply by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy.

Air Liquide S.A. is a French multinational company which supplies industrial gases and services to various industries including medical, chemical and electronic manufacturers. Founded in 1902, after Linde it is the second largest supplier of industrial gases by revenues and has operations in over 80 countries. It has headquarters at the 7th arrondissement of Paris. Air Liquide owned the patent for Aqua-Lung until it expired.
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.
Sigma-Aldrich is an American chemical, life science, and biotechnology company owned by the multinational chemical conglomerate Merck Group.
Showa Denko K. K., founded in 1939 by the merger of Nihon Electrical Industries and Showa Fertilizers, both established by a Japanese entrepreneur Nobuteru Mori, is a Japanese chemical company producing chemical products and industrial materials.
Praxair, Inc. was an American worldwide industrial gases company. Founded in 1907, Praxair was the largest industrial gases company in North and South America, and the third-largest worldwide by revenue. In 2018 it merged with Linde AG to form Linde plc. The Praxair name was discontinued on September 1, 2020 in the US.
Airgas, an Air Liquide company, is an American supplier of industrial, medical and specialty gases, as well as hardgoods and related products; one of the largest U.S. suppliers of safety products; and a leading U.S. supplier of ammonia products and process chemicals. The company is headquartered in Radnor Township, Pennsylvania.
An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.
A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic temperatures to produce high purity gasses such as argon, nitrogen, oxygen, and many more with 1 ppm or less impurities. The process is based on the general theory of the Hampson-Linde cycle of air separation, which was invented by Carl von Linde in 1895.
