Indian Army finds a system to convert liquid oxygen to oxygen gas

The Indian Army has found a solution for efficient conversion of liquid oxygen to low pressure oxygen gas that can be given to COVID-19 patients at their hospital beds. According to the Army's statement, "Over seven days, the team of Army engineers in-direct consultation and material support from the Council of Scientific and Industrial Research and Defence Research and Development Organisation put together a working solution using vaporisers, pressure relief valves and liquid oxygen cylinders. Since oxygen was transported in liquid form in cryogenic tanks, quick conversion of liquid oxygen to oxygen gas and ensuring availability at the patients' bed was a critical challenge faced by all hospitals managing COVID patients.”

 

As part of the continued fight against COVID -19, #IndianArmy#CorpsofEngineers has developed a Mobile Low-Pressure Oxygen System. The system converts Liquid Oxygen to Oxygen Gas & ensures its availability to the patients. The engineers' team used a self-pressurising liquid oxygen cylinder of small capacity (250 litres) and processed it through a specially designed vaporiser and directly usable outlet pressure (4 Bar) with leak-proof pipeline and pressure valves.

 

The team was led under Major General Sanjay Rihani. A prototype with two liquid cylinders capable of feeding oxygen gas for 40 beds for a period of two to three days was made functional at the base hospital in Delhi. The team has also tested a mobile version to cater for typical shifting requirements in hospitals. The system is economically viable and is safe to operate since it obviates high gas pressure in the pipeline or cylinders and does not require any power supply to operate. The system is capable of replication in a quick time frame.
