PSA ( Pressure Swing Adsorption) Technology a revolution in Non Cryogenic Air Separation and Oxygen Generation Technology uses special grade of ZMS ( Zeolite Molecular Sieve).

3. Principles

It uses zeolite molecular sieve as sorbent, produces oxygen by making use of the PSA principle.

Under certain pressure, zeolitemolecular sieve has different oxygen/nitrogen adsorption capacity, i.e. much more nitrogen adsorption capacity than oxygen adsorption capacity. PLC controls pneumatic valve open/close to realize two adsorption towers' alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation and produces oxygen with desired purity.

4. 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.
