What is PSA working principle?
Dried and filtered pressurized air enters nitrogen generator system. In this system working according to PSA (Pressure Swing Adsorption) principle, there are two adsorption columns. In these olumns, there arehigh durable and quality CMS granules (carbon molecular sieve)supported with special bedding system. Pressurized air entering the lower inlet of the column, moves towards upside of the column.
The mesh size on CMS garanules, is larger than oxygen molecule size (O2 : 0.28 nm) and smaller than nitrogen molecule size (N2 : 0.32 nm). Accordingly, oxygen molecules, moving alongwith adsorption column, are adsorped inside the CMS mesh, and larger nitrogen molecules moves are allowed to leave the system.
Nitrogen gas production
While adsorption column filled with CMS saturated with oxygen, starts releasing pressure and oxygen (regeneration), adsorption column filled with CMS released pressure and oxygen, starts seperating oxygen and nitrogen molecules from each other (adsorption) and generates nitrogen.
Adsorption columns working in this way, adsorption for a while and then regeneration for the same while, provides continual nitrogen generation. Adsorption and regeneration processes duration changing according to application, is automatically controlled by solenoid valves with long lifetime cycle.
