Chemical properties Oxygen is one of the most active elements, except for helium, neon and Except for rare gases such as argon and some inactive metals, oxygen can form compounds with all elements. Oxygen is a combustion-supporting gas that can support life, chemical bleaching and as an oxidant
Application Oxygen is a very useful gas in metallurgy It has been widely used in the fields of chemical industry, biochemistry, medical, avionics and military scientific research, especially in the medical field. Recently, some people call oxygen medicine, which shows that its role is extraordinary. As an industrial gas, oxygen mainly comes from the atmosphere and passes through the air. Obtained by means of separation, there are also small amounts derived from electrolysis of water and other methods. Oxygen products can be divided into industrial oxygen, medical oxygen, aviation breathing oxygen, high-purity oxygen, pharmacopoeia oxygen, electronic oxygen and other varieties. Mixed with various fuel gases, oxygen is Welding and cutting metal processing provide heat energy. Oxygen-rich combustion is beneficial to improve production efficiency and reduce harmful combustion by-products.
Oxygen is mainly used in the following industries: steel smelting/life support/welding cutting/sewage treatment/pulp bleaching/glass manufacturing /Petroleum refining/Metal manufacturing/Chemical processing/Lighting Oxygen is used as a transport gas in medicine to bring anesthetic (nitrous oxide) into the human body to achieve the effect of anesthesia.

Storage, Transportation and Safety Oxygen and nitrogen are so-called permanent gases, and their boiling points are relatively close, so the storage and transportation of oxygen are basically the same as those of nitrogen. Oxygen can be transported according to the amount of gas used by the user. Depending on the geographical location and other circumstances, you can choose the transportation method of pipeline transportation, tank truck transportation, cylinder transportation, or tube bottle bundle transportation. Different from nitrogen and other inert gases, because oxygen is a strong oxidant, although it cannot burn, it can support combustion. Its chemical properties are extremely active and can react chemically with many elements while releasing heat. Therefore, safety is the first factor that must be considered when filling, storing and transporting oxygen. In oxygen production, filling, storage, transportation and use places, oxygen is easy to be released indoors. When the concentration of oxygen in the environment exceeds the volume fraction, there is a risk of fire. Therefore, in places where the oxygen concentration is likely to increase, ventilation devices should be installed and the oxygen concentration should be monitored and kept away from heat and fire sources. Maintenance and process treatment should contain oxygen Before the container is installed, it must be replaced with inert gas. When the oxygen content (volume fraction) drops below the following level, work can begin. Oxygen filling stations should be operated in strict accordance with safety operating procedures. Cylinders filled with other gases (especially flammable gases) are not allowed to be used to fill oxygen, and cylinders filled with oxygen are not allowed to be used to fill other gases.
