  1. 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.

  2. Main Components of a Membrane Type Nitrogen System •Air compressor •Inlet filters •Dryer unit •Air heater (Not mandatory but optional) •Membrane •Nitrogen storage reservoir Points to Bear in Mind While Choosing a Nitrogen Generator Membrane System You must keep in mind that the performance of membrane depends a lot on the operating temperature of the air. The performance gets badly hampered if the operating temperature reduces below 45 degree Celsius. An air heater is therefore required to maintain the temperature of the air. Usually, 55 degree Celsius is a good temperature for optimum membrane performance. If the temperature of the feed air is already in between 55-60 degree Celsius then, an air heater is not required. It is an optional component. You must also keep in mind that the operating temperature must not exceed 65 degree Celsius; otherwise the generation unit will trip. Benefits of a Nitrogen Generator Membrane System Let’s take a quick look at some of their benefits- •Simple construction •Highly reliable •Low maintenance •Easy to operate •Not bulky in weight •Low noise Hope you found the post useful.
