Vpsa process flow chart

The Psa Oxygen Generator uses zeolites as adsorbent materials to trap oxygen at high pressure in one adsorption tower, the process then swings to low pressure to desorb the oxygen while the other adsorption tower starts with adsorption process. The two process then alternate in the two adsorption towers, realized with control valves and PLC to have continuous production of qualified oxygen.
Vacuum Pressure Swing Adsorption (VPSA) technology can produce the desired gas much more efficiently. It draws the gas through the separation process with a vacuum, generated by a blower, The systems apply pressurized gas to the separation process and also apply a vacuum to the purge gas.

Easy erection, low start-up capital, pre-fabricated skids, shorter erection period than cryogenic systems;
Low power consumption, low operating cost;
Simple operation, high degree of automation, intelligent control, highly flexible control;
Fast production, short startup time;
High operational stability, high safety, key components from well-known suppliers;
Long service life, top quality zeolite molecular sieve.
Little work of maitenance, low maitenance costs;
