Nagaland gets its first PSA oxygen generation plant

First Pressure Swing Adsorption (PSA) oxygen generation plant has become operational at Naga Hospital Authority Kohima (NHAK) from yesterday.

Nagaland Health Minister S Pangnyu Phom inaugurated the first PSA plant of 300 LPM at NHAK after which production of medical oxygen will commence on a regular basis.

After the event, S Pangnyu Phom took to Twitter and thanked PM Narendra Modi and Dr. Harsh Vardhan for generously supporting the State in combating the pandemic.

The PSA oxygen generation plant has been funded by the PM CARES fund. On May 10, a sample of oxygen generated at NHAK, PSA Plant was sent for testing.
The test report stated that the tested sample of medical oxygen is according to IP 2018 Standard Quality and is fit for use for Medical Purposes.

The construction of two more PSA plants, one each in Dimapur and Mokokchung districts is under progress, and a few more PSA oxygen generating plants will be installed in other districts of the state, funded by UNDP and UNICEF.

What is Pressure Swing Adsorption technology?

It is a simple technology used for separating gases like Hydrogen, Nitrogen, and Oxygen from ambient air. The technology uses the fact that certain gases under high pressure tend to get attracted to solid surfaces or absorbent materials like zeolites, activated carbon, and molecular sieves.

How do Oxygen PSA Generators work?

Air contains 78% nitrogen, 21% Oxygen,0.9 % argon, and 0.1% other trace gases. Through a technique known as Pressure Swing Adsorption(PSA), an Oxygen Generator extracts this oxygen from compressed air.

Synthetic Zeolite Molecular Sieve mostly absorbs nitrogen and is used in the Pressure Swing Adsorption process for generating the enriched oxygen gas from ambient air.
