It is possible to generate nitrogen gas from the atmosphere. The device that does it is known as the PSA Nitrogen Generator. It is a device that can separate out nitrogen from other gases like oxygen. The generator uses the principle of adsorption to work, where a carbon molecular sieve or similar such material is used to adsorb oxygen so nitrogen passes through and can be separated.
A key requirement is a non-reactive environment. What this means is oxidation and chemical reactions have to be avoided in the presence of oxygen.
The PSA Nitrogen Generator made by Creative Oz Air uses the molecular air sieve separation technology. The technology employs carbon molecular sieves that can generate nitrogen from the air in the atmosphere. We make use of a proprietary technique that helps us achieve a higher efficiency during gas separation.
Creative Oz Air’s PSA Nitrogen Generator has two beds with carbon molecular sieves. Compressed air is then passed through the beds. Nitrogen is then passed out through one of the beds, while the other bed is at the same time regenerated to atmospheric pressure using depressurization. The process employed is known as PSA or Pressure Swing Adsorption.
Creative Oz Air’s PSA Nitrogen generator produces nitrogen at a purity of 99% to 99.99995%. We add a purification unit so the raw nitrogen, which is 99% pure, can be further purified.
While nitrogen generators are produced by many companies, there are specific benefits that we offer. When you use Creative Oz Air’s PSA Nitrogen generator, you get to experience many advantages. They include:
The PSA Nitrogen generator from Creative Oz Air is perfectly customizable. You can get the generator to suit your capacity needs. While we can manufacture the generator as per your required capacity, the standard capacities are 1, 2, 5, 10, 25, 50, 75, 100, 150, 200, and 300 Nm3 per hour.
| Criteria | PSA Nitrogen Generator | Nitrogen Cylinder |
|---|---|---|
| Cost | Running cost is low. | Costs of rental/delivery would increase over time. |
| Transfer and handling | It is not required. | Extremely cumbersome process. |
| Purity | High purity nitrogen is produced steadily. | Purity levels are not uniform, and can vary from cylinder to cylinder. |
| Efficiency | Unlimited gas supply that is continuous. | Interruption in supply of cylinder is possible. |
| Dependence | No dependency since you produce nitrogen yourself. | You have to depend on suppliers to supply cylinders. |
| Convenience | Maintenance easy and low. | Frequent cylinder replacement needed. |
The principle of selective adsorption governs the working of the PSA nitrogen generator. Compressed air passes through a vessel that has carbon molecular sieve (the adsorbent material). The sieve adsorbs oxygen and lets nitrogen go through. Adsorbed oxygen is then released, so you can get pure nitrogen as the end product of the process.
The PSA Nitrogen generator we offer can offer purity up to 99.9999%. Depending on your needs, we can offer you a generator that can produce the best purity level to meet your application requirements.
You can keep these factors in mind while choosing a PSA nitrogen generator:
Look for a generator that meets all your needs, and is offered by a reputed manufacturer.
You must carry out routine maintenance like changing the filter and replenishing the adsorbent material. The schedule for maintenance depends on your use and the environmental condition in your premises.
Yes, it is possible. Retrofitting can be used to integrate our PSA Nitrogen air generator into your existing compressed air systems. Proper planning is required. The right setup and configuration will help in making this possible.
