Overcoming all hurdles and finding new solutions, Indian Railways is continuing its journey of bringing relief by delivering Liquid Medical Oxygen(LMO) to various states across the country. First Oxygen Express to Uttarakhand is reached on 11th May 2021 with 120 MT of Oxygen from Tatanagar in Jharkhand. The Oxygen Express loaded with containers of Liquid Medical Oxygen (LMO)
About Liquid Medical Oxygen (LMO)
Liquid Medical Oxygen is high purity oxygen used for medical treatment. It has been developed for use in the human body. Due to its low melting and boiling points, oxygen is in a gaseous state at room temperature. Liquification enables storage in larger volume and easier transportation
There are various methods through which LMO can be produced. The most common production method is the separation of oxygen in Air Separation Units (ASUs). ASUs are production plants that separate large volumes of gases. Air Separation Units (ASUs) use a method known as the 'Fractional Distillation Method' to produce pure oxygen from atmospheric air. In the Fractional Distillation Method, the various gases constituting atmospheric air are separated into different components after cooling them into a liquid state. Liquid oxygen is then extracted from it.
