Simple PSA Oxygen Generator Working Principle for Producing Lots of Oxygen

Oxygen is an important gas occupying 21% of the atmospheric air. Apart from inhaling, we need oxygen for many other purposes as well. It is needed in the medical field for the treatment of patients who are unable to breathe properly. Oxygen is also used in several industrial sectors for the oxidation of metals or non-metals. MVS Engineering Pvt. Ltd offers PSA oxygen plants of various capacities, which can be installed at the sites of clients for instant oxygen production. The PSA oxygen generator working principle is a simple yet prime one that can yield huge volumes of gas.

The PSA oxygen generator working principle of MVS Engineering

MVS Engineering offers a PSA oxygen plant that works on Pressure Swing Adsorption technology. This device contains Zeolite molecular sieves and active alumina for filtering oxygen from the compressed atmospheric air. Usually, air contains 78% nitrogen and only 21% oxygen. So, Zeolite absorbs all the nitrogen, which is then released back into the air through an exhaust pipe. Now, only oxygen is left, which is approximately 95% pure, having only traces of argon and other gases. This is the basic PSA oxygen generator working principle that delivers oxygen continuously.

MVS Engineering has designed its PSA oxygen generator with two identical vessels filled with molecular sieves and alumina. When the sieves of one vessel become saturated with nitrogen, the oxygen generation process automatically shifts to the second vessel. Meanwhile, the molecular sieves of the first vessel are relieved from nitrogen by releasing the gas into the air again. Thus, the operation switches from one vessel to another, making oxygen generation a continuous process.

As for this PSA oxygen generator, the working principle is easy to understand, and anyone can handle this device even without any technical know-how.

If a more powerful oxygen plant is needed, the VPSA oxygen generator of MVS Engineering can be the ideal option in that case. It has a higher flow of oxygen due to very low-pressure blowers, which also makes the device more energy-efficient. But the delivering pressure of oxygen is only 1.3 Kg/cm2 in a VPSA plant. If clients need higher pressure, they can ask for a booster compressor with this device.
