A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. [1] 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 ...
Almost every plant built between 1964 and 1992 had large single-train designs with syngas manufacturing at 25–35 bar and ammonia synthesis at 150–200 bar. Braun Purifier process plants utilized a primary or tubular reformer with a low outlet temperature and high methane leakage to reduce the size and cost of the reformer. Air was added to ...
Because the liquid-to-gas expansion ratio of nitrogen is 1:694 at 20 °C (68 °F), a tremendous amount of force can be generated if liquid nitrogen is vaporized in an enclosed space. In an incident on January 12, 2006 at Texas A&M University , the pressure-relief devices of a tank of liquid nitrogen were malfunctioning and later sealed.
Linde Engineering designs and builds large-scale chemical plants for the production of industrial gases including oxygen, nitrogen, argon, hydrogen and carbon monoxide, as well as large plants associated with the processing of natural gas, LNG, Liquefied petroleum gas and the manufacture of olefins.
Liquid hydrogen is used by NASA in the Space Shuttle as a rocket fuel. A nitrogen generator Membrane nitrogen generator. Simpler gas separation technologies, such as membranes or molecular sieves used in pressure swing adsorption or vacuum swing adsorption are also used to produce low purity air gases in nitrogen generators and oxygen plants.

1954 – Established the Kawasaki plant, liquefied oxygen (Japan's first) and high-purity nitrogen, argon started manufacturing. 1955 – Tokyo factory (formerly Kamata factory) was separated, and Nippon Rika Kogyo Co., Ltd., changed its name to Nippon Sanso Corporation its trade name.
