Nitrogen gas generators, rather than cylinders supplied by third parties, are becoming more popular with industrial clients in the United States. The ability to produce nitrogen gas on-site has various benefits, including the ability to save money and time.
Due to the fact that air is used as a raw material, generators function more safely and efficiently while providing a reliable supply of high-purity gas.
First and foremost, what is the function of a Nitrogen Generator?
Nitrogen gas is typically removed from the atmosphere by nitrogen generators, which may be either fixed or mobile. In industrial settings, the majority of nitrogen production systems are divided into two categories:
- Nitrogen generators using pressure swing absorption (PSA)
- Membrane-based nitrogen producers

What if we looked at them from a different angle?
High-pressure nitrogen gas has a great attraction to zeolite and granular activated carbon. This is how the PSA nitrogen generator works. Depending on the pressure applied, different gases in a mixture may be absorbed at different rates. The gas will begin to be released when the pressure is reduced.
When Membrane Nitrogen Generators are installed, it usually has two towers: one for absorption and the other for regeneration. An adsorbent prevents nitrogen gas from passing through but enables oxygen, CO2, water molecules, and other contaminants to flow through the absorption tower. By lowering the pressure, the N2 that was absorbed may be restored. When the adsorption tower is operating, the other tower is in the process of regenerating itself.
The nitrogen generators are often used to extract high-purity nitrogen gas from a stream of compressed air in a variety of related professions, including electronics manufacturing, food and beverage packaging, medical facilities, chemical industries, wastewater treatment plants, and others.
Membrane-Based Process for the Generation of Nitrogen
It is possible and viable to use nitrogen membrane technology in place of PSA nitrogen systems. Nitrogen gas is separated via a high-selectivity membrane. The topic under consideration is a semi-permeable layer made up of flexible, cylindrical filaments. Pores ranging in size from 0.3 to 10 microns may be found in this material.
A cylinder-shaped container holds the nitrogen gas and is filled with a dry, pressurized air stream in order to separate it. Only nitrogen may pass the barrier; oxygen, water vapor, inert gases, and airborne contaminants are all prevented. Predicting membrane selectivity is mostly dependent on the size of the pore. A membrane-type nitrogen generator may create gas with purity levels of up to 99.95 percent on a volumetric basis.
To meet the needs of a wide range of industries, Nitrogen Generators offers a wide range of portable nitrogen generators.
Pressure swing absorption and membrane nitrogen generators may produce nitrogen gas with a purity level of up to 99 percent by volume. The way we do things is what separates us from one other. According to their needs in terms of price, quality, and operational efficiency, industrial clients may select between these two solutions.
Nitrogen Generators also provides skid-mounted membrane nitrogen generating systems to companies in addition to PSA generation equipment. Our nitrogen generators may be rented out for short periods of time.
- Three of the most significant benefits are provided by on-site nitrogen generators.
- PSA and membrane nitrogen producers have a number of advantages, some of which are listed below.

The Advantages of Having More Time on Your Hands
Customers in the industrial sector that produce their own nitrogen gas may be able to avoid having to shut down their operations. Compressed nitrogen gas cylinders are sent from suppliers to industrial customers at a cost of time and money every year due of logistical constraints. While a nitrogen-generating system assures that you have access to ultra-pure gas for your operations around the clock, seven days a week, it is not as reliable.
Nitrogen production on-site is more cost-effective than acquiring the gas from a third-party supplier because of the savings in transportation and storage, Nitrogen producers on membranes are particularly vulnerable to this (as opposed to PSA systems). In order to transport nitrogen gas, either an in-house logistics staff or trucking providers with reasonable freight rates will be needed.

Last Word: A combination of security and dependability is required
If the nitrogen gas is generated on-site, the system is safer than one that relies only on nitrogen gas canisters, a huge number of people may be harmed by leaks of highly concentrated nitrogen gas from broken cylinders, especially if the gas is present in confined areas. In addition to saving space, PSA and membrane filtration systems also lessen the dangers connected with storing these containers.
