With this variant of PSA developed for use in laboratory nitrogen generators, nitrogen gas is produced into two steps: in the first step, the compressed air is forced to pass through a carbon molecular sieve to produce nitrogen at a purity of approximately 98%; in the second step this nitrogen is forced to pass into a second carbon molecular ...
High nitrogen purity: PSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide – up to 99.9995% nitrogen. But in most cases they do not produce more than 98.8% nitrogen with the remainder being argon that is not separated from the nitrogen by the usual PSA process.
A nitrogen generator Bottle of 4Å molecular sieves. Pressure swing adsorption provides separation of oxygen or nitrogen from air without liquefaction. The process operates around ambient temperature; a zeolite (molecular sponge) is exposed to high pressure air, then the air is released and an adsorbed film of the desired gas is released.
PSA generators provide a cost-efficient source of oxygen. They are a safer, [ 9 ] less expensive, [ 10 ] and more convenient alternative to tanks of cryogenic oxygen or pressurised cylinders. They can be used in various industries, including medical, pharmaceutical production, water treatment, and glass manufacture.
Air with low oxygen concentration is produced by hypoxic air generators, also known as air splitting units. There are three different types of hypoxic air generators: membrane-based, PSA-based, and VSA-based. VSA-based hypoxic air generators usually have a lower energy consumption compared to PSA-based and membrane-based generators.
Electronics Materials and Equipment, including high purity gas, gas mixtures, purification devices and other hardware and services – provides stable supplies of nitrogen and various material gases to the electronics industry. They also supply equipment such as small-scale nitrogen generators, MOCVD equipment and exhaust gas abatement systems.
Peak Scientific is a Scottish manufacturer of gas generators for analytical laboratories. [ 1 ] [ 2 ] [ 3 ] Headquartered in Glasgow , United Kingdom, it specialises in the production of nitrogen, hydrogen, and gas generators, mainly for the fields of liquid chromatography–mass spectrometry and gas chromatography .
National and regional parks in Italy. The national parks of Italy are protected natural areas terrestrial, marine, fluvial or lacustrine, which contain one or more intact ecosystems (or only partially altered by anthropic interventions) and/or one or more physical, geological, geomorphological, biological formations of national and international interest, for naturalistic, scientific, cultural ...
