Water Soluble Oxygen Gas O2 / Non Toxic Gas High Concentration
Oxygen is the most abundant chemical element by mass in the Earth's
biosphere, air, sea and land. Oxygen is the third most abundant
chemical element in the universe, after hydrogen and helium. About
0.9% of the Sun's mass is oxygen.
Oxygen constitutes 49.2% of theEarth's crust by mass as part of
oxide compounds such as silicon dioxide and is most abundant
element by mass in the Earth's crust. It is also the major
component of the world's oceans. Oxygen gas is the second most
common component of the Earth's atmosphere, taking up 20.8% of its
volume and 23.1% of its mass. Earth is unusual among the planets of
the Solar System in having such a high concentration of oxygen gas
in its atmosphere: Mars and Venus have much less. The O2
surrounding those planets is produced solely by ultraviolet
radiation on oxygen-containing molecules such as carbon dioxide.
The unusually high concentration of oxygen gas on Earth is the
result of the oxygen cycle. This biogeochemical cycle describes the
movement of oxygen within and between its three main reservoirs on
Earth: the atmosphere, the biosphere, and the lithosphere. The main
driving factor of the oxygen cycle is photosynthesis, which is
responsible for modern Earth's atmosphere. Photosynthesis releases
oxygen into the atmosphere, whilerespiration, decay, and combustion
remove it from the atmosphere. In the present equilibrium,
production and consumption occur at the same rate of roughly
1/2000th of the entire atmospheric oxygen per year.
Cold water holds more dissolved O2. Free oxygen also occurs in
solution in the world's water bodies. The increased solubility of
O2 at lower temperatures has important implications for ocean life,
as polar oceans support a much higher density of life due to their
higher oxygen content. Water polluted with plant nutrients such as
nitrates or phosphates may stimulate growth of algae by a process
called eutrophication and the decay of these organisms and other
biomaterials may reduce the O2 content in eutrophic water bodies.
Scientists assess this aspect of water quality by measuring the
water's biochemical oxygen demand, or the amount of O2 needed to
restore it to a normal concentration.
1. Physical properties
|Commodity||High purity oxygen gas|
|Hazardous class for transort||2.2|
2. Typical technical data (COA)
|8ltr||1||100bar||According to the valve type|
|40ltr||5.5||135bar||According to the valve type|
|Other sizes and other standards are also available|
|Life support and recreational use||An application of O2 as a low-pressure breathing gas is in modern
space suits, which surround their occupant's body with pressurized
air. These devices use nearly pure oxygen at about one third normal
pressure, resulting in a normal blood partial|
pressure of O2.
|Industrial||Smelting of iron ore into steel consumes 55% of commercially
produced oxygen. In this process, O2 is injected through a
high-pressure lance into molten iron, which removes sulfur
impurities and excess carbon as the respective oxides, SO2 and CO2.|
|Chemical||Ethylene is reacted with O2 to create ethylene oxide, which, in
turn, is converted into ethylene glycol; the primary feeder
material used to manufacture a host of products, including
antifreeze and polyesterpolymers.|
|Other||Oxygen is used in medical applications, metal cutting and welding,
oxidizer in rocket fuel, and in water treatment.
