Medical oxygen usage small plant hospital usage PSA oxygen generator complete system

Working Principle

After the impurities such as oil, water, dust, etc. are removed from the compressed air through the air purification system, the compressed air goes into the absorption tower which has been installed with zeolite molecular sieve. Nitrogen, carbon dioxide, water vapor, etc. in the air are absorbed largely by the molecular sieve, while the oxygen penetrates the adsorbent due to its large diffusion rate, so as to realize separation of nitrogen and oxygen.
When the absorption of the impurities such as nitrogen is saturated in the absorption tower, reducing the pressure can make the zeolite molecular sieve release the absorbed impurities and regenerate, so as to realize repeated recycling.

PSA ( Pressure Swing Adsorption)

Technology a revolution in Non Cryogenic Air Separation and
Oxygen Generation Technology uses special grade of ZMS ( Zeolite Molecular Sieve).
The compressed air is passed through a Twin Tower PSA module interconnected with automatic
changeover valves. After passing through a Refrigerated Dryer air gets dried. Dried compressed air
will now come in contact with bed of Zeolite molecular sieves (ZMS). Zeolite Molecular Sieves are special
grade of adsorbent which have the property of preferential adsorption of nitrogen molecules.
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. The outgoing oxygen
gas is sent to a surge vessel where the minimum pressure will be maintained with the help of Back
pressure Regulator

The process of oxygen generation plant
Oxygen Generator consist of two columns filled with molecular sieve(CarboTech AC Gmbh). Pre-treated compressed air enters the active column and follows up through the CarboTech. Nitrogen and the other gases are being adsorbed while the oxygen passes through. The active column is pressurized. When pressure is released, column becomes inactive and completely regenerate. In order to secure steady flow two columns are used, one is active while the other is inactive. At the end of cycle they switch roles.
Oxygen from oxygen generator enters oxygen buffer. From there regulated oxygen is fed into the high pressure oxygen compressor where the oxygen is boosted and fed the filling ramp where oxygen cylinders are filled.
Our comapct plant is built on the skid or frame with one central electric socket enabling quick start up. All components are already connected in the factory, so no extensive installation is required.



Working Principle

Atmospheric desorption PSA oxygen generator use the clean compressed air as raw material,zeolite molecular sieve as the adsorbing material ,use the pressure swing adsorption principle to get the oxygen under normal temperature.According to the difference adsorbing capacity of oxygen,nitrogen up the zeolite molecular sieve surface,and the difference diffusion rate of oxygen,nitrogen under ZMS,through Programmable Controller control the sequencing valve open/close,complete Pressure adsorption ,Decompression desorption process,complete Separation of oxygen and nitrogen ,get the demanded purity oxygen.
