PSA Principle
This process consists of 2 beds filled with Carbon Molecular Sieves (CMS). When pre-filtered compressed air is passed through one CMS bed, Nitrogen comes out as the product gas. The waste gas (oxygen, carbon dioxide, etc.) is discharged back into atmosphere. Upon saturation of the CMS bed, the process switches nitrogen generation to the other bed, while allowing the saturated bed to undergo regeneration by depressurization to atmospheric pressure. This ensures continuous supply of Nitrogen to your process
| Capacity | 1 NM³/hr to 1500 NM³/hr |
| Purity | Up to 99.9999% |
| Pressure | Up to 10-Bar (without Booster) |

Technology CarboTech AC GmbH (Germany),
This is Carbo tech Carbon Molecular sieves (CMS) Technology to produce low cost Nitrogen from Air. Azote Eng. Company has long experience and know-how in Design and Manufacturing of such plants. Carbon Molecular sieves remove moisture and Oxygen from Air. So up to 95.999% purity dry Nitrogen gas is produced.
PSA Nitrogen Gas Plant Models
We offer the following models depending on the purity and balance gas content required for your process:
| PPM (Impurity) | Percent (Impurity) | Percent (Purity) |
|---|---|---|
| 1 PPM | 0.0001% | 99.9999% |
| 10 PPM | 0.001% | 99.999% |

| 5000 PPM | 0.5% | 99.5% |
Process Diagram
PSA - Pressure Swing Adsorption Process Description
The PSA process for nitrogen generation is divided into two phases. In the initial phase, the Carbon Molecular Sieve adsorbs oxygen from compressed air, which contains 79% nitrogen and 21% oxygen. During this stage, the pure nitrogen is withdrawn as product gas at the absorber outlet. In the second phase, the oxygen is released at low pressure - and the next cycle can start. The interconnection of two absorber vessels, which are alternately charged with compressed air and de-pressurized, allows the quasi-continuous generation of high purity nitrogen.
