Technology 03 May 2021 Indian Institute of Technology (IIT) Bombay has come up with a creative and ingenious solution to address the shortage of medical oxygen for the treatment of Covid-19 patients in the country. The pilot project, which has been tested successfully relies on a simple technological hack: conversion of Pressure Swing Adsorption (PSA) Nitrogen Unit to PSA Oxygen Unit! Initial tests done at IIT Bombay have shown promising results. Oxygen production could be achieved at 3.5 atm pressure, with a purity level of 93- 96 per cent. This gaseous oxygen can be utilised for Covid-related needs across existing hospitals and upcoming Covid-19 specific facilities by providing a continuous supply of oxygen.
