However, liquid storage tanks must be made using high strength materials so that they could withstand extreme temperatures and pressure. High quality materials are used that meet the standards of American Society of Mechanical Engineers (ASME) code.
LIQUID OXYGEN PORTABLE
This storage method takes up less space than the compressed gas cylinder, and you can transfer the liquid to a small, portable container at home. When released, the liquid converts to a gas and you breathe it in just like the cylinder gas. By the way, 1 liter of liquefied oxygen equals 840 liters of gaseous oxygen. Liquid Oxygen Oxygen is stored as a very cold liquid in a container very similar to a thermos. Liquid storage is preferred to gaseous storage is economical as well as effective because there are no leakages. Liquid Oxygen Portable CAIREs Companion 1000 and Companion 1000T High-Flow Portable Liquid Oxygen units offer lightweight and robust oxygen therapy options. Then, liquid oxygen is stored in cryogenic storage tanks. The meaning of LIQUID OXYGEN is a pale blue transparent mobile magnetic liquid obtained by compressing gaseous oxygen and used chiefly in liquid-oxygen. Here oxygen is distilled till it meets the commercial specifications of purity. Oxygen is formed at the bottom of the distillation column. Liquid Medical Oxygen Plant Project Cost in India Afterwards, the air is directed into high pressure distillation column where oxygen is separated from other gases such as nitrogen, argon, etc. After being compressed the air is sent into a cleanup system where it is cleaned up of all impurities such as moisture, carbon dioxide and hydrocarbons.įor getting liquefaction of the air, it is passed through heat exchangers where it is cooled into a cryogenic liquid, defined as liquefied gases that have boiling point below -90 degrees Celsius. There are non-cryogenic methods as well such as pressure swing method which are used for producing oxygen with purity of 90-93% but is not used for large scale production of oxygen with high purity.Ĭryogenic method takes atmospheric air which is then fed into the compressor. Cryogenic technique is the most commonly used for producing liquid oxygen for industrial and medical applications. Oxygen is generated by liquefaction of atmospheric air in the air separation unit (ASU). Liquid oxygen is used in numerous applications such as melting, refining and making of steel & other metals, providing medical & biological support, mining, production, and making of stone & glass product, etc. For generation of liquid oxygen we use cryogenic distillation process for liquefaction & separation of oxygen from air. The non-reactive gas is generated commercially for application in industries and medicine. It is necessary for human beings due to respiratory and combustion processes. It is odorless, colorless and tasteless gas which is reactive and forms oxides with all elements except helium, neon, argon and krypton. Oxygen is also found in the crust of the earth making up around 46.6 per cent. It comprises 21 per cent of earth’s atmosphere by volume. Oxygen is utterly vital for our sustenance on the planet earth.
