PSA Oxygen Gas Plant
Oxygen produced by our machine uses the PSA (Pressure Swing Adsorption) process. This process has been used for producing medical grade oxygen for a long time and is a very mature and well‐established technology. Zeolites molecular sieves are used in this process for separating constituents of air such as nitrogen, oxygen, carbon dioxide, carbon monoxide etc. Argon and Oxygen cannot be easily separated and hence the Oxygen from this plant will contain argon also. However, argon is inert and has no effect on the human body when dispensed with oxygen. It is like breathing nitrogen (70-78% of the atmosphere is nitrogen).
Nitrogen is also inert like argon. In fact, the Humans breathe Oxygen is only 20‐21% in the atmosphere with largely the balance being Nitrogen. Oxygen that comes in cylinders is of 93‐ 95% purity & it is produced in bulk quantities using Cryogenic Separation Process & PSA Separation Process. However, as explained earlier, Cylinder Oxygen & Oxygen from our machines can be used interchangeably without any worries. Commercial benefits of installing an in‐ house Oxygen Generation plant at any hospital. In most cases the simple answer would be yes. Barring large cities with abundant Cylinder Suppliers, the Cylinder costs are quite exorbitant and are a drain on any Hospital or Medical Facilities finances on a recurring monthly basis. Furthermore, operators don’t usually wait for Cylinders to get empty before changing them before night shift to avoid having Cylinders go empty in the middle of the night.
