Oxygen (Oxygenium) is the most common chemical element on Earth. Almost half (49%) of the Earth's crust and a fifth (21%) of the atmospheric air volume consist of oxygen. This substance is part of water, plants and all live organisms. Also, oxygen is part of the vitally important elements, such as proteins, fats and carbohydrates. Oxygen is key for gas metabolism: breathing and oxidation.
Currently, there are three ways to produce pure oxygen: chemical (used in laboratory conditions), water electrolysis, and the oxygen also is obtained from air separation..

    • Gas without color
    • taste
    • and smell
    • Heavier than air
    • Slightly soluble in water
    • At -183 degrees Celsius
    • it turns into a mobile blue liquid
    • Freezes at -219°C.
    • Non-toxic
    • non-flammable
    • non-explosive
    • But! Oxygen is a strong oxidizer
    • so it greatly enhances the combustibility of other substances.

    Pure oxygen in gaseous and liquid states is used in various industrial fields:

    • In electronics manufacturing. Oxygen is used to produce semiconductors and make optical fiber;
    • In the production of measuring and laser equipment;
    • Oxygen may be used for scientific purposes;
    • The gas is used in food production;
    • In the chemical industry;
    • Oxygen is used in medicine as a component of respiratory mixtures;
    • In the oil and gas sector;
    • In the metallurgy industry, oxygen is used for oxy-fuel welding, plasma and laser cutting, and soldering;
    • Oxygen is used as a component in gas calibration mixtures.

    Under natural conditions, oxygen is a colorless and tasteless gas with no smell. It is a very strong oxidizer and can cause the ignition of other substances. Oxygen can be transported by any means of transport in cylinders in a cooled liquid state. Oxygen is classified as hazard class 2. Liquefied oxygen may present a cryogenic hazard to humans or animals. When transporting cylinders of pure oxygen, it is necessary to maintain a low-temperature regime (-183...-185 degrees Celsius), monitor the pressure, avoid overheating, open flames, impacts, or vibrations of the gas containers.

    Pure nitrogen is dangerous when transporting

    Can be transported by

    • train
    • truck
    • ship
