PSA Principle:
PSA (Pressure Swing Adsorption) is an economical alternative for Onsite Production of Oxygen for Medical use and is in use for over 40 years in the medical industry. PSA process comprises of NMS95MO Sieves filled towers and is based on the fact that different gases have the property to be attracted to different solid surfaces more or less strongly. This happens with nitrogen, which is attracted to the NMS95MO Sieves. As the air is compressed, the nitrogen is forced into the crystalline cages of the NMS95MO Sieves and the oxygen is less adsorbed and conveyed to the end of the NMS95MO Sieves bed and ultimately recovered in the oxygen buffer tank. Two NMS95MO Sieves beds are used together: One adsorber air under pressure until it gets saturated with nitrogen while oxygen passes through. The second adsorber begins to do the same while the first one is regenerated as nitrogen is expulsed (desorbed) by releasing the pressure. The process repeats again, storing the oxygen in an oxygen buffer tank from where the system is connected to oxygen analyzer which detects the purity of oxygen in the system
How It Works
MEDIKRAFT Medical Oxygen Generator System works on the principle of Pressure Swing Adsorption, widely termed as PSA. This conventional gas separation technology is being used to separate Oxygen from the Compressed air. The major components are a pair of Adsorbent Vessels, Surge Tank, Switching Valves, Intelligent PLC, Oxygen Analyzer and Instruments. The adsorbent vessels filled with NMS95MO Sieves preferentially adsorbs Nitrogen and C02 whereas Oxygen is not adsorbed by NMS95MO Sieves due to its larger molecular size and passes through the adsorber to the surge tank. Based on the prefixed time interval the online adsorber switches to regeneration mode and Adsorbed gas from NMS95MO Sieves are purged out to the atmosphere. During this operation Oxygen analyzer monitors the oxygen concentration and allows Oxygen Gas to a storage tank.

Having Trouble Handling Oxygen Supply In Hospital??
Here is your one step solution which is Installing MEDICAL Oxygen Generator..
Description | PSA Plant | Oxygen Cylinders |
COST SAVING | Only Electricity charges you have to pay. | Costs 60-80% higher than PSA Plant.
|
Safety | System is safer i.e. no transportation is required and peak hour consumption can be maintained. | Availability at the time of emergency, monopoly of vendors start. |
Purity | Direct purity analyzer is available to see the purity of oxygen. | Once can’t assure purity of oxygen in cylinder, from being unorganized suppliers. |
Filled Capacity | Not Applicable, since it has display showing flow of Oxygen. | We can’t judge the capacity filling is always on level. |
Prevent Losses | No Such losses, applicable in it as system provides what it produces.
| 10% is always a loss before change over, some gas is left in the cylinder residual. |
Less Manpower | PSA is automatic system, only 01 trained operator can manage whole system.
| Cylinder system needs 2 persons in 8 hours shift to change cylinder banks. |
Reduces Overheads | No as such billing is required. | Stock maintenance, billing, tracking status etc. involves cost. |

PSA PROCESS
PSA (Pressure Swing Adsorption) Technology a revolution in non-cryogenic air separation and Nitrogen Generation Technology by the use of special grade of MS (molecular Sieve). The compressed air is passed through a twin tower PSA module interconnected with automatic changeover valves. At a time one tower remains under Nitrogen production cycle, whereas the other tower undergoes regeneration which is achieved through depressurization of the tower to atmospheric pressure.
MEDIKRAFT Nitrogen Generator System works on the principle of Pressure Swing Adsorption, widely termed as PSA. This conventional gas separation technology is being used to separate Nitrogen from Compressed air. The major components are a pair of adsorbent vessels, Surge tank, Switching valves, Intelligent PLC, Oxygen analyzer and instruments. The adsorbent vessels filled with Carbon Molecular Sieves preferentially adsorbs Oxygen and C02 whereas Nitrogen is not adsorbed by Carbon Molecular Sieves due to its larger molecular size and passes through the adsorber to the surge tank. Based on the prefixed time interval the online adsorber switches to regeneration mode and Adsorbed gas from Carbon Molecular Sieves are purged out to the atmosphere.

SYSTEM OPERATION
The earth's atmosphere is comprised of approximately 78% nitrogen and 21% oxygen. Once atmospheric air is compressed, its pressure is increased while proportions of nitrogen and oxygen remain unchanged. Once the air is compressed it must be filtered and dried prior to its introduction to the Nitrogen Generation systems.
Step 1
Inlet valves direct the compressed air flow into one of the two adsorption chambers (Right) where the CMS ( Carbon Molecular Sieve) adsorbs the oxygen content while allowing the nitrogen to pass creating a high purity nitrogen stream that then exits the adsorption chamber and is stored in the nitrogen storage/buffer tank. The other adsorption chamber (Left) is depressurized to atmosphere through the exhaust valve enabling the CMS to release and expel any previously adsorbed oxygen to atmosphere.
Step 2
Just Prior to the end of the (Right) absorption cycle the exhaust valve on (Left) is closed and balance valves are opened to equalize pressure in the two adsorption tanks.
Step 3
The inlet valves are then inverted bringing the regenerated (Left) tower online to adsorb oxygen leaving a high purity nitrogen gas stream. The other adsorption chamber(RIght) which was previously online adsorbing oxygen is depressurized so the CMS will release and exhaust any previously adsorbed oxygen to the atmosphere.
Step 4
This cyclic action continues allowing the generator to produce a steady stream of high purity nitrogen gas. This process is commonly known as Pressure Swing Adsorption (PSA).
