The Working Principle of Membrane Type Nitrogen Generation System Nitrogen generators are crucial to fire sprinkler systems as corrosion concerns in fire sprinkler systems increased day by day. Nitrogen generator membrane systems are quite popular on account of a variety of reasons. Both PSA (Pressure Swing Absorption) nitrogen generators and Membrane nitrogen generators are popular in the industry. Both generator types are known for producing high quality nitrogen from compressed air, but in this post we will take a look at some of major benefits of membrane nitrogen generators.
Membrane Nitrogen Generator Process Explained A nitrogen generator membrane system works on the principle of selective gas permeation. You might be aware that each gas has a unique permeation rate. As the compressed air stream flows through the membrane, gases such as oxygen (O2) and carbon dioxide (CO2) with faster permeation rates are released back into the atmosphere. This is waste gas which is released back into the atmosphere along with some nitrogen as well. Now the nitrogen which is already devoid of O2 and CO2 now passes out the other end of the separator. This is done at a lower pressure for collection. It might interest you that unlike PSA systems, a nitrogen receiver tank is not a necessarily required component in a nitrogen generator membrane system.
