However, there are some limitations to consider when using PSA. Firstly, the process requires a continuous supply of compressed air, which can be energy-intensive. Secondly, the effectiveness of PSA can be reduced at higher pressures, resulting in lower nitrogen purity levels. Additionally, the adsorbent material used in the process may degrade over time and need replacement.
B. Membrane separation
Another method of generating pure nitrogen gas is membrane separation. This process utilizes a semi-permeable membrane that selectively allows the passage of nitrogen molecules while blocking other gas molecules, such as oxygen.
The membrane separation method involves compressing atmospheric air and passing it through a bundle of hollow fiber membranes. The nitrogen molecules, being smaller and more permeable, diffuse through the membrane walls, leaving behind an enriched nitrogen stream. This process is continuous and can achieve nitrogen purities ranging from 95% to 99.9%.
One advantage of membrane separation is its simplicity and cost-effectiveness compared to other methods. It does not require the use of adsorbents or cryogenic temperatures, resulting in lower maintenance and operational costs. Additionally, membrane separation systems can be easily scaled up or down to meet specific nitrogen requirements.
However, membrane separation has its limitations. The purity level achieved with this method is generally lower compared to PSA or cryogenic distillation.
