What is liquid oxygen? What is the function of liquid oxygen?
Liquid oxygen, also known as liquid oxygen, is a form of oxygen that is cooled to a liquid state at extremely low temperatures. It has the following benefits:
High purity: Liquid oxygen has a high purity, usually above 99%, which makes it very useful in some industrial and medical applications that require high-purity oxygen.
Easy to store and transport: After liquefaction, the volume of liquid oxygen is greatly reduced, making it easy to store and transport, especially suitable for occasions that require a large amount of oxygen or places where oxygen supply is not easily provided through pipelines.
High efficiency: In industrial processes that require a large amount of oxygen, such as steel manufacturing, chemical synthesis, etc., using liquid oxygen is more efficient than using gaseous oxygen.
Medical use: Liquid oxygen can be used in hospitals and home healthcare, providing a convenient source of oxygen for patients in need of oxygen therapy.
Aerospace: Liquid oxygen, as a part of rocket propellants, is an important oxidizer for liquid fuel rockets and is crucial for space launches.
Research application: In scientific research, liquid oxygen can be used to provide ultra-low temperature environments, which is essential for low-temperature physics experiments and some special scientific studies.
Metal cutting and welding: Liquid oxygen can be used to increase the temperature of flames and is widely used in metal cutting and welding processes.
Environmental Protection: Liquid oxygen can be used to improve combustion efficiency, reduce pollutant emissions, and contribute to environmental protection.
Emergency supply: In natural disasters or emergency situations, liquid oxygen can be quickly converted into gaseous oxygen for rescue operations.
The use of liquid oxygen requires strict safety measures because it has strong oxidizing properties and can support combustion. Therefore, corresponding safety regulations must be followed during use, storage, and transportation.
