Nitrogen Generation, Supply and Application
Nitrogen generation is one of the old technologies that results in the production of high-quality pure nitrogen gas meant for various applications. Air is 78% nitrogen and when the gas is compressed in a tank, it remains dry. There are several businesses that specialize in manufacturing nitrogen generators for different industrial and commercial uses. Finding such companies should never be a daunting task. Three main technologies are used in nitrogen generations as follows;
• PSA (pressure swing adsorption) – This is the most popular and recent technology in the generation of pure nitrogen gas that can be supplied. This technology involves the use of an adsorbent which is a solid molecule where different gas mixture is pressured on to. The swing operation involves two main processes; one taking place above atmospheric temperature, while the other one happening below atmospheric temperature. Two containers are used. When air mixture is introduced into the adsorbent containing container, oxygen, water and CO2 is allowed to diffuse into the porous structure while nitrogen passes to the other tank. In the reverse process, the diffused compounds and oxygen are released and passed to a vent expelling them back to the atmosphere. The mechanism behind PSA is well understood and used for most industrial and commercial delivery of pure nitrogen.
