Medical oxygen concentrators are used in hospitals or at home to concentrate oxygen for patients. [8] 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 ...
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.
Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
Typical oxygen purities range in from 97.5% to 99.5% and influences the maximum recovery of oxygen. The refrigeration required for producing liquid products is obtained using the Joule–Thomson effect in an expander which feeds compressed air directly to the low pressure column. Hence, a certain part of the air is not to be separated and must ...
Most humans can function at rest with an oxygen level of 15% at one atmosphere pressure; [1] a fuel such as methane is combustable down to 12% oxygen in nitrogen. A small room of 10 meter 3 has 2.08 meter 3 (2080 liters) or 2.99 kg of oxygen which would occupy 2.62 liters if it was liquid. [2]
Powdered oxygen bleach, oxygen bleach packs, or liquid oxygen bleach should be added directly to the drum of both front and top load washing machines rather than putting in dispensers or compartments.
