Technology

The compressed air is passed through a Twin Tower PSA module interconnected with automatic changeover valves. At the bottom of PSA towers, Activated Alumina is provided which has tendency of adsorbing moisture from compressed air. After passing through this bed of Activated Alumina air gets dried. Supply of dry compressed air from this layer of desiccant (activated alumina) will be continuous without any interruption. Dried compressed air will now come in contact with bed of carbon molecular sieves (CMS). Carbon Molecular Sieves are special grade of adsorbant which have the property of preferential adsorption of oxygen 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 two towers of PSA modules are inter-connected with automatic changeover valves through pneumatic signal given by solenoid valve which in turn get the electrical signal from the timer provided in the control panel. The changeover time cycle will be 1 + 1 minute. The outgoing nitrogen gas is sent to a surge vessel where the minimum nitrogen pressure will be maintained with the help of Back pressure Regulator. The product nitrogen will now be sent to the consumer point through a pressure reducing valves at required pressure.

Salient Features:

1. The PSA type gas generator is fully automatic and the gas of proper specification is made available within short period after start-up.2. This type of gas generator does not require any fuel.3. Since the feed stock for this gas generator is air, there is no problem like soot formation or presence of Co2 etc. the common problem in fuel combustion based gas generator.4. The gas generator is very compact requiring very small floor area.5. Depending on the pressure in the nitrogen storage tank, the gas generator keeps running with ON/OFF operation like compressed air installation.

Therefore, the gas generator would work only to the extent of meeting your gas requirement as and when needed.

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 adsorbant 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.

ATTRACTIVE FEATURES 1. Fully Automatic Operation requiring no special attention- Manless Operation 2. Generates Oxygen as and when required Plug It, Switch On & Forget 3. Easy to install and maintain Skid Mounted & precommissioned 4. Purity of Oxygen upto 93-95% can be achieved 5. PSA (Twin Tower Pressure Swing Adsorption) Based upto 150 NM3/hr 6. VPSA (Three Tower)For 150 Nm3/hr to 1500 Nm3/hr 7. VSA (Three Tower) For capacities more than 1500 Nm3/hr
