How Does PSA Nitrogen Generator Work?

PSA oxygen gas generator in India is of absolute necessity in hospitals and other areas. It helps to maintain the supply of oxygen. The generator can separate different gas mixture components such as nitrogen and oxygen with the help of the solid substance known as adsorbents. 

This adsorbent in the PSA nitrogen generator helps to separate the gas mixtures. The process of separation is based on density level. Under high pressure, gasses like nitrogen exhibit a strong affinity for adsorbents such as granular activated carbon and Zeolite.

So, various gas components will be absorbed at different rates. This will depend on the amount of pressure. Gas will desorb under low pressure. The PSA nitrogen generator has two towers:

  • One tower is for the absorption of the gas
  • The second is for regeneration of the gas

The air mixture coming from the compressor will enter into the absorption tower. Here, the gas will contact the adsorbent and allow the separation of the nitrogen gas, carbon dioxide, oxygen, and other gasses. However, the pressure is reduced to recover the nitrogen gas, and gas will be desorbed. 

This way, nitrogen gas is separated from the mixture. Also, the separated oxygen can be used in hospitals and other areas where oxygen is needed. The PSA nitrogen generator is widely applied in industrial areas and hospitals for the fastest nitrogen recovery in its purest form.

Nitrogen has been used in food packaging and hospitals; it is used as a preservative method. The application is designed to separate the gasses by changing the pressure level. Another method is applied for separating the gasses, such as swing adsorption processes.

Gasses will be adsorbed at two stages at different time intervals. The moisture, oxygen, and carbon dioxide diffuse during the adsorption stage to form a structure, whereas the nitrogen molecules travel to the adsorbed-adsorbent container. This helps to gain pure nitrogen gas, which you can use for various purposes. Moreover, it is also useful for having the pure form of oxygen, which can be used as a lifesaver support system.

Why Are Medical Oxygen Generators Essential for Home Care?

Medical oxygen generators are currently vital for home healthcare, providing reliable and cheap oxygen to persons with respiratory issues. Because they supply oxygen, these devices are essential as more individuals receive home medical care. Seniors, recovering patients, and others with long-term respiratory problems need a medical oxygen generator to improve their quality of life. Consistent Oxygen Supply Instead of refilling oxygen cylinders, a medical oxygen generator provides a consistent supply. This ensures patients have a consistent oxygen supply, reducing emergency and hospital visits. These machines offer high-quality medical oxygen whenever needed, using advanced filters and concentration methods. Better Comfort and Movement Home oxygen generators make it easier to move around without cumbersome oxygen tanks. Modern oxygen concentrators are lightweight, portable, and can be used indoors or outdoors. This improves mobility, keeping people engaged while helping to breathe. Aff...

6 considerable factors for selecting the best PSA oxygen generator

Every healthcare facility requires an appropriate oxygen supply station, whether it’s a small-scale gas plant or a generator. It isn’t the same as that of other forms of oxygen supply plants often used in different industries. Medical-grade oxygen is the purest form of the gas, without any trace of halogen, oxidants, and polymers. Although several types of generators are available in the market, PSA oxygen generator is supposedly the most efficient and reliable for medical supplies. Having said that, we have briefly illustrated the major factors you should keep in mind to choose the best PSA generator for medical-grade oxygen. Oxygen requirement : Firstly, you need to run a thorough assessment of the specifics of oxygen requirement for the healthcare facility. For instance, you need to decide the required gaseous flow rate, oxygen volume, purity level, concentration, and so on to shortlist the options present in hand. Purity levels : Another factor you should consider is the purity lev...

What are the common medical gases used in hospitals?

The structure of hospitals is developing so quickly. Structural development doesn't mean only its outer presentation. The overall interior, technological developments, staff qualification, training and improvement programs, advanced facilities, and more factors are included here. That is the reason why India is known for its world-class treatment facilities. The role of medical gases is an avoidable fact. You can not ignore how efficiently medical gases are strengthening the medical sector. Our medical gas manufacturers have increased production by understanding their importance and demand. You may notice a hike in the number of medical oxygen plants in India. Along with oxygen, some other gases are frequently used by hospitals regularly. Medical gases and their uses in hospitals: It is hard to cover all medical gases in such a short word limit. So today you will get to know about 5 medical gases and their uses: Oxygen : Oxygen supports the inhalation of patients. Some patients fac...
