Answer: IIT Bombay
Notes: Indian Institute of Technology-Bombay (IIT-B), has set up a demonstration unit to convert nitrogen generators, into oxygen generators by modifying the existing nitrogen plant set up. The oxygen generated by this plant at IIT-B lab was tested and found to be 93-96% pure and at 3.5 atmospheric pressure. Nitrogen plants work on Pressure swing adsorption (PSA) technology, where air from the atmosphere is sucked in, filtered and nitrogen is extracted. Oxygen, a by-product, is released back into the atmosphere.
