As the country gasps for breath and lingers in an abysmal demand for medical oxygen, the Indian Institute of Technology (IIT) Bombay has come up with a creative and ingenious solution by converting nitrogen generator into oxygen generator.
The pilot project which has been tested successfully relies on a simple technological hack: conversion of PSA (Pressure Swing Adsorption) 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% to 96 %. This gaseous oxygen can be utilised for Covid-related needs across existing hospitals and upcoming Covid-19 specific facilities by providing a continuous supply.
How can the nitrogen unit be converted into an oxygen unit? “It has been done by fine-tuning the existing Nitrogen Plant setup and changing the molecular sieves from Carbon to Zeolite,” says Prof. Milind Atrey, Dean (R&D), IIT Bombay, who led the project.
“Such nitrogen plants, which take air from the atmosphere as raw material, are available in various industrial plants across India. Therefore, each of them could potentially be converted into an oxygen generator, thus helping us tide over the current public health emergency”, he added.
The pilot project is a collaborative effort between IIT Bombay, Tata Consulting Engineers, and Spantech Engineers, Mumbai, who deal with PSA Nitrogen & Oxygen plant production.
This setup for the experiment was developed within three days, and the initial tests have shown promising results.
Amit Sharma said: “We are delighted to partner with IIT Bombay and Spantech Engineers, and contribute towards an innovative solution for emergency oxygen generation using existing infrastructure towards helping the country tide over the current crisis. Such partnerships between industry and academia can accelerate our vision towards the Atma-Nirbhar Bharat.”
Prof. Subhasis Chaudhuri, Director IIT Bombay, congratulated all the involved parties and said that such collaborations between academia and industry are highly desirable and essential for the growth and success of our nation.
