Reliable and Uninterrupted Nitrogen Production in Industrial Facilities
Nitrogen gas used in industrial production processes is of great importance in terms of high purity, continuous supply, and process safety. Traditionally met by cylinder or liquid nitrogen systems, nitrogen needs can now be met more efficiently and controllably with PSA nitrogen generators, enabling businesses to produce nitrogen on-site.
Nova Gas Industry develops PSA technology nitrogen generator systems for the needs of different sectors and offers complete nitrogen production solutions for industrial facilities. The main purpose of the system is to separate nitrogen from other gases in the ambient air and produce nitrogen gas at the required purity and flow rate.
PSA
PSA is an abbreviation for Pressure Swing Adsorption and is called Pressure Swing Adsorption in Turkish. This technology is based on the principle of adsorbing oxygen and other components in the air using pressure changes and separating nitrogen.
In a PSA nitrogen generator system, the process begins with an air compressor. The compressor compresses the air it takes from the atmosphere and sends it to the system. The compressed air is then balanced in an air tank and then conveyed to the next equipment in a controlled manner.
The compressed air is passed through filtration and drying stages to remove unwanted components such as particles, oil aerosols, and moisture. At this point, equipment such as pre-filters, air dryers, and final filters come into play. This ensures that compressed air is sent to the PSA towers as clean and dry as possible.
Nitrogen Separation in PSA Towers
The most important part of the system is the PSA unit, which consists of two adsorption towers. As seen in the image, Adsorption Tower A and Adsorption Tower B operate alternately within the system.
The towers generally contain adsorbent material with a molecular sieve structure. When compressed air enters the tower, oxygen and some other components are retained by the adsorbent, while nitrogen gas passes through the system and is separated as a product gas.
Thanks to the alternating operation of the two towers, while one tower produces nitrogen, the other tower enters the regeneration phase. Then, a change of duty takes place. This working principle forms the basis of continuous nitrogen production.
The pneumatic valve group in the system ensures that the airflow is directed to the correct tower and that the production and regeneration cycles of the towers are automatically managed. The control panel helps monitor and control the operating parameters of the system.
Where is the Produced Nitrogen Stored?
The nitrogen from the PSA towers can be sent to a nitrogen tank (buffer/receiver tank) as needed. The nitrogen tank helps maintain the pressure and flow rate balance between the system and the point of consumption.
To maintain the necessary quality conditions before sending the nitrogen gas to the point of use, an outlet filter can also be included in the system. The resulting nitrogen is then directed to the production line or directly to the process equipment.
The waste gas produced during the regeneration phase of the system is discharged in a controlled manner. If necessary, an exhaust silencer can be used to reduce the noise level that may occur during regeneration.
Advantages of PSA Nitrogen Generators
On-site nitrogen production in industrial facilities can provide businesses with many advantages:
- Uninterrupted nitrogen supply: The required nitrogen can be produced on-site.
- Alternative to cylinder logistics: Continuous cylinder replacement, transportation, and storage processes can be reduced.
- Capacity according to need: Flow rate, purity, and operating pressure can be determined according to process needs.
- Automatic operation: Thanks to the control system, the production cycle can be managed automatically.
- More controlled operation: Nitrogen production and consumption can be kept under control within the facility.
- Long-term use: With proper maintenance and correct operating conditions, systems can be designed to operate for a long time.
- Optimization of space utilization: Compressor, tank, Filters, dryers, and PSA towers can be designed within a single system.
PSA
Nitrogen Generator In Which Sectors Is It Used?Nitrogen gas is used in many different industrial applications. In particular, laser cutting, metal processing, food packaging, electronics, chemistry, pharmaceuticals, oil and gas, heat treatment, and manufacturing processes are among the areas where nitrogen use is widespread.
For example, in laser cutting applications, high-purity nitrogen can be used as an auxiliary gas in the cutting process. In the food sector, nitrogen can be used to reduce oxidation and control the atmosphere inside the packaging of products.
Therefore, when selecting a PSA nitrogen generator, not only the device capacity but also; The desired nitrogen purity, flow rate, operating pressure, inlet air quality, operating time, and application area should also be considered.
