An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.
With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30 and 50 ppb. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers.
In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases (hydrogen, oxygen, and nitrogen) into a liquid or solid. [ 2 ] [ needs update ] The most common objective is to prevent vapors being evacuated from an experiment from entering a vacuum pump where they would condense and contaminate it.
Aside from its use to supply medical oxygen, or as a substitute for bulk cryogenic or compressed-cylinder storage, which is the primary oxygen source for any hospital, PSA has numerous other uses. One of the primary applications of PSA is in the removal of carbon dioxide (CO 2 ) as the final step in the large-scale commercial synthesis of ...
A water trap may be provided to collect condensed water from the absorbent reaction and from metabolic product. [24] Monitoring functions may include: [24] Cylinder pressure (analog and digital) Estimated remaining duration of use until residual low pressure warning is activated; Temperature indication; Automatic recording of warning signals
The conversion of the oxygen gas [15 O]O 2 to 15 O-water can happen in two ways: the in-target production and the out-of-target external conversion.The in-target production method uses a small amount of hydrogen (about 5%) that is added to the gas, whereby 15 O-water is formed and trapped in a cooled stainless steel loop.

When the reagents are highly susceptible to oxidation, traces of oxygen may pose a problem. Then, for the removal of oxygen below the ppm level, the inert gas needs to be purified by passing it through a deoxygenation catalyst. [4] This is usually a column of copper(I) or manganese(II) oxide, which reacts with oxygen traces present in the inert ...
