Pure-play helium, also known as primary helium or green helium is helium that is extracted from the earth as the main product. Since the early 20th century, most of the world's helium supply has been extracted from natural gas as part of the nitrogen rejection process. The preference for primary helium is driven by the planned reduction in use ...
A Horton sphere (sometimes spelled Hortonsphere), also referred to as a spherical tank or simply sphere, is a spherical pressure vessel, which is used for industrial-scale storage of liquefied gases. Example of materials that can be stored in Horton spheres are liquefied petroleum gas (LPG), liquefied natural gas (LNG), and anhydrous ammonia. [1]
Fulton sold the company to Vortec, Inc. [19] The vortex tube was used to separate gas mixtures, oxygen and nitrogen, carbon dioxide and helium, carbon dioxide and air in 1967 by Linderstrom-Lang. [20] [21] Vortex tubes also seem to work with liquids to some extent, as demonstrated by Hsueh and Swenson in a laboratory experiment where free body ...
Closed-cycle gas turbine schematic C compressor and T turbine assembly w high-temperature heat exchanger ʍ low-temperature heat exchanger ~ mechanical load, e.g. electric generator. A closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon, [1] [2] etc.) for the working fluid as part of a closed thermodynamic ...
Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...
All commercial production of helium comes from natural gas.There are two basic types of commercial helium deposits: natural gas produced primarily for the hydrocarbon content, typically containing less than 3 percent helium; and gas with little or no hydrocarbons, produced solely for the helium, which typically makes up between 5 and 10 percent of the gas.
A gas regulator attached to a nitrogen cylinder. 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.
A buffer gas adds pressure to a system and controls the speed of combustion with any oxygen present. Any inert gas such as helium, neon, or argon will serve as a buffer gas. A buffer gas usually consists of atomically inert gases such as helium, [1] [2] argon, or nitrogen. [3] Krypton, neon, and xenon are also used, primarily for lighting.
