The Indian Institute of Technology (IIT), Bombay, has come up with an ingenious solution to address the shortage of medical oxygen in the country. The institute is piloting a new technology to convert a nitrogen plant into an oxygen generator. Initial tests done at IIT, Bombay, have shown promising results.
The pilot project, which has been tested successfully, relies on a simple technological intervention of converting a Pressure Swing Adsorption nitrogen unit into a PSA oxygen unit, according to an official statement.

It claimed that initial tests conducted at the Indian Institute of Technology (IIT) Bombay have shown “promising results”.
The oxygen production could be achieved at “3.5 atm pressure with a purity level of 93 per cent to 96 per cent”, the statement said.
This gaseous oxygen can be utilised for COVID-19- related needs across the existing hospitals and upcoming COVID-19-specific facilities by providing a continuous supply of oxygen, it said.
“It (conversion of nitrogen unit into an oxygen unit) has been done by fine-tuning the existing nitrogen plant setup and changing the molecular sieves from Carbon to Zeolite,” the statement said quoting Prof Milind Atrey, dean (R&D), IITB, who led the project.
Atrey said suchnitrogen 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 said.
The pilot project is a collaborative effort among IIT Bombay, Tata Consulting Engineers and Spantech Engineers, Mumbai, who deal with the PSA nitrogen and oxygen plant production, the statement said.
