Oxygen Production Steps
with PSA Technology
• Pressurization: By compressing air into the tank, the desired oxygen pressure is achieved.
• Adsorption: Zeolite molecular sieves allow oxygen to pass through under high pressure while
retaining nitrogen and other gases.
• Regeneration: By reducing the tank pressure, the saturated zeolite molecules are released and
made ready for reuse.
• Pressure Equalization: After the regeneration cycle, the valve is opened to equalize the pressure
between the two tanks, minimizing energy loss.
