VPSA Oxygen Generator
A vacuum pressure swing absorption or VPSA oxygen generator is one of the more effective tools at extracting oxygen from the atmosphere around us.
The VPSA can extract oxygen from the ambient air stream by absorbing one of the most common elements in the air around us—nitrogen—thus producing a flow of purified oxygen. For higher volumes, the VPSA is very effective.

VPSA Oxygen Generator mainly consists of the blower, vacuum pump, cooler, adsorption system, oxygen buffer tank and control system
Air Blower & Vacuum Pump
The blower provides air for the whole oxygen system. The blower whose exhaust pressure meets the design conditions is selected according to the design conditions of the VPSA oxygen unit, combined with the user's operating conditions. The vacuum pump ensures the normal desorption of the whole oxygen-generating system in the ideal vacuum state so that the oxygen plant can continuously absorb nitrogen while generating oxygen.
Cooler
Compressed air at high temperature and high pressure after pressurization in the blower goes through the water cooler to reduce the temperature down to the required operating level, and then is sent to the adsorption tower for adsorption.
Adsorption System
The adsorption system consists of 2 adsorption vessels equipped with the zeolite molecular sieve, piping and valves, etc. Compressed air at low temperature and high pressure enters from the bottom of tower A. When flowing through the adsorbent bed, impurities such as CO, water vapor, and N2 in the air are adsorbed, while oxygen is collected through the adsorption bed at the top of the adsorber as the product gas. At the same time, the B tower is in regeneration. When the adsorption of tower A almost reaches equilibrium, low-temperature and high-pressure air goes into the B tower for adsorption by the control system. Tower A and B thus alternately operate to achieve continuous oxygen production.
Oxygen Buffer Tank
To store product gas (oxygen) and stabilize the pressure of the whole set of equipment.
Control System
The engineer inputs the pre-written valve control program into the PLC controller, which regulates the opening and closing of each pneumatic valve through the solenoid valve to enable the adsorption system to adsorb and regenerate within the appointed time.
There are three main phases of the Pressure Swing Adsorption Generator
Adsorption: The pre-treated air passes into a vessel containing zeolites to remove any moisture and/or CO2 and adsorbs the nitrogen while oxygen passes through the vessel outlet. Before the adsorption capability of the zeolite is exhausted the adsorption process is interrupted. the top of the column. This takes place until the adsorber saturation.
Deadsorption: The saturated zeolite is regenerated (i. e. the adsorbed gases released) by means of pressure reduction below adsorption pressure. This is achieved by a dry running vacuum pump. The resulting off gas is vented to atmosphere. To maintain a continuous flow of oxygen supply a surge tank is installed.
Repressurization: The adsorber is repressurized with pure gas and is now ready to receive more feed gas to start the process over.
