Description:

The nitrogen generators operates on pressure swing adsorption (psa) technology. Psa technology is based on the selective adsorption phenomena of gas molecules under pressure on the surface of highly porous and efficient adsorbent, in this case of nitrogen generation the adsorbent is carbon based molecular sieve (c. M. S. ) the nitrogen gas generator consist of twin tower system filled with special grade of carbon molecular sieves. At a time one tower keeps in production cycle and other in regeneration cycle. When compressed air passed through c. M. S. Bed the molecules of oxygen, moisture & other unwanted gases are adsorbed on surface of c. M. S. And nitrogen which is not adsorbed by c. M. S. Comes out of adsorption tower and is collected in a surge vessel. For continuous generation of nitrogen, two adsorption towers are provided which are interconnected with auto change over valves controlled by sequence programmer. After saturation of one tower with oxygen the process automatically changes over to another tower and thus the nitrogen production is continuous. Nitrogen is an inert gas, so that it has use very widely in various types of industries. The onsite nitrogen generators are custom made and can be adjusted to give the desired nitrogen quality for your process and application
