Oxygen generation hack devised by IIT Bombay to address India's LMO shortage!

Amid the rise of COVID infection, the dearth of oxygen supplies across the nation has emerged as a major concern.

In a novel achievement, IIT Bombay has developed a simple tech hack that can convert a nitrogen plant to an oxygen generating unit, an official said here on Thursday. This opens up an avenue that can single-handedly address the acute shortage of medical-grade oxygen across the country, amid the pandemic hour. The success of this pilot project has not only manufactured the lifesaving gas but also hope among lakhs of affected people, in times of dread and despair.

Necessity is the mother of invention!

The pilot conversion project was a collaborative effort of IIT Bombay and Tata Consulting Engineers and Spantech Engineers, Mumbai. While the premier engineering institute was the brain behind this run, the resources were provided by the fellow partner, who deals with PSA nitrogen and oxygen plant production, pivotal to the translation.

The Spantech Engineers installed the required plant components at the Indian Institute of Technology Bombay, for evaluation using the existing infrastructure at the institute's nitrogen facility. The entire process was completed within 3 days, paving way for the project to be a hit. The technique is simple and involves the conversion of Pressure Swing Absorption nitrogen unit to PSA oxygen unit and consequently, LMO can be produced at 3.5 atm pressure with a purity level of 93-96%.

To further validate the proof of this concept, a PSA nitrogen plant in the Refrigeration and Cryogenics Laboratory of IIT, was identified for conversion. Its success instils hope for heightened LMO production in India to solve its shortage, in the backdrop of a ferocious pandemic.

A partnership to beat the pandemic

Lead by the Dean of IIT Bombai, Professor Milind Atrey, the project team has confirmed that fine-tuning the existing nitrogen plant setup and altering their molecular sieves from carbon to zeolite can produce oxygen. "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," Atrey further 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," said Amit Sharma, Managing Director of TCE, on the success of the pilot project.

IIT-B Director Prof Subhasis Chaudhuri, Rajendra Tahiliani, Promoter of Spantech Engineers and alumnus IIT-B, Raj Mohan, MD, Spantech Engineers and others have lauded the efforts of the team for their efforts and partnership on this project.

'Breathe India' initiative by IIT Kanpur alumni racks up over 3 cr for tackling rife LMO crisis!

After successful operations in Delhi, they are expanding their reach to UP with the help of a Lucknow based NGO.

When citizens across the country are grappling due to a dire shortage of oxygen amid the second wave of the pandemic, a group of alumni from IIT Kanpur have taken it upon their shoulders to assure enhanced supplies of the medical necessity. Through a crowdfunded initiative, 'Breathe India', the group has raised more than 3 crores and ordered oxygen concentrators for medical centres across Delhi. Now, they are expanding this scope of help to Uttar Pradesh with the help of a Lucknow-based NGO.

Right Walk Foundation in Lucknow to support 'Breathe India' in UP

After remarkable triumphs in the first week of the campaign, the alumni collective has now associated with Lucknow's Right Walk Foundation for its programs in Uttar Pradesh. Here, the group aims to distribute concentrators, oxygen cylinders, oximeters and other equipment among the underprivileged individuals. With this, the net target of the campaign has been augmented to ₹4 crores and the initiators anticipate that they would reach this goal soon.

Working on the lines of 'social inclusion', Right Walk Foundation assures support and assistance to slum-dwelling communities across 11 districts of Uttar Pradesh. Highlighting the need for public advocacy, the organisation attempts to create an ecosystem of equity and sustainability.

Successful in assuring widespread relief


As per the information provided on their campaign page, over 250 concentrators are being provided through this program to hospitals and COVID care centres. Marking collaborative efforts with SaveLife Foundation, this group of samaritans have been successful in assuring relief in a much greater measure, than their initial expectations. All of the resources are being delivered across Delhi, working in alignment with the requirements observed by the Delhi Government.

The facilitators consist of Ashutosh Ranka, Isha Agarwal, Nikhil Asati, Kavya Eluru, Randhir Shah- each one from a different batch of IIT-K. Together, they have embarked on a journey to help scores of citizens and save hundreds of Life.
