2. Oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Oxygen_concentrator

   An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) 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 .

3. Chemical oxygen generator - Wikipedia

   en.wikipedia.org/wiki/Chemical_oxygen_generator

   A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture. The mixture has an indefinite ...

4. Zeolite - Wikipedia

   en.wikipedia.org/wiki/Zeolite

   Zeolite-based oxygen concentrator systems are widely used to produce medical-grade oxygen. The zeolite is used as a molecular sieve to create purified oxygen from air using its ability to trap impurities, in a process involving the adsorption of nitrogen, leaving highly purified oxygen and up to 5% argon.

5. Carbon dioxide scrubber - Wikipedia

   en.wikipedia.org/wiki/Carbon_dioxide_scrubber

   The thermal decomposition of calcite is performed in a lime kiln fired with oxygen in order to avoid an additional gas separation step. Hydration of the lime (CaO) completes the cycle. Lime hydration is an exothermic reaction that can be performed with water or steam. Using water, it is a liquid/solid reaction as shown here: CaO(s) + H 2 O (l ...

6. Portable oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Portable_oxygen_concentrator

   Portable oxygen concentrator used with bottle humidifier. POCs operate on the same principle as a home concentrator, pressure swing adsorption. [6] The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.
