Tata Advanced Systems Ltd. (TASL), a wholly-owned subsidiary of Tata Sons and strategic Aerospace and Defence arm of the TATA Group has been awarded a tender by the Indian Government for setting up pressure swing adsorption (PSA) units or on-site Oxygen Generator units across India.
The estimated cost for setting up each Oxygen generation unit is Rs. 75 lakh pus taxes. Sites are being prepared at various hospitals in parallel.
More Details About the Oxygen Generation Units Order to TASL
Indian Government has ordered a total of 500 PSAs, out of which 450 PSA order has gone to TASL and remaining 50 to Trident Pneumatics. These Oxygen plants are planned to be set up within three months. These 500 Oxygen plants were sanctioned under PM CARES Fund.
What is Pressure Swing Adsorption (PSA) Units: Air is 21% Oxygen, 78% Nitrogen, 0.9 per cent Argon and 0.1% other trace gases. An Oxygen generator separates Oxygen from compressed air through a unique process called PSA.
PSA plants derive Oxygen from the atmospheric air, which is purified and supplied through pipes to patients. Such Oxygen is required to have 99.5 percent purity.
Technical Features of the Oxygen Plants: “These Medical Oxygen Plants are designed for a flow rate of 1,000 litres per minute (LPM). The system can cater to 190 patients at a flow rate of 5 LPM and charge 195 cylinders per day. The Medical Oxygen Plant (MOP) technology has been developed by DRDO based on the On‐Board Oxygen Generation for LCA Tejas. These plants will overcome the logistics issues of Oxygen transportation and help the COVID-19 patients in emergency”, as mentioned in the article by Press Bureau of India by Ministry of Defence dated 4th May 2021.
