Working Principle and
System Description
The VPSA-O2 after desorption is sent into the adsorption vessel of the VPSA-O2 system by a blower after being filtered to remove mechanical impurities. The adsorber is a double-vessel system, and its product is oxygen. N2, CO2 and H2O in the air are adsorbed and a vacuum pump will be applied after saturated adsorption to ensure the adsorbents in the adsorption vessel are completely desorbed for regeneration.
The dual-vessel system enables continuous oxygen generation, with cyclic switching of program control valves managed by a PLC-based control system.
Process Steps for VPSA Oxygen Production
The general operating steps to separate and enrich oxygen by vacuum pressure swing adsorption oxygen plants are shown below. In one cycle, each adsorption vessel needs to undergo five steps: adsorption, pressure reduction, vacuum desorption, purging, and pressure increasing.
Adsorption
The air is sent into the adsorption tower by the Roots blower after mechanical impurities are removed.
The H2O, CO2, and N2 in the air stay in the adsorbent bed. And the riched O2, adsorbed litle in the adsober, is discharged from the outlet of the tower.
A portion of the oxygen produced by this step is sent to the buffer tank, and the remaining portion is reserved for the next step to regenerate and boost the pressure in the adsorption tower.
Pressure Reduction
In the pressure reduction step, oxygen-rich gas passes along the vessel outlet. The gas enters another vessel in the pressure increasing step, and the pressure goes up.
Vacuum Desorption
The vacuum pump is applied after saturated adsorption to ensure the adsorbents are completely desorbed for regeneration.
Purging
Oxygen is used to purge the bed as part of the regeneration sequence.
Pressure Increasing
The vessel pressure is raised as part of the cyclic switching program to prepare for the next adsorption step.

Characteristics of Vacuum Pressure Swing Adsorption (VPSA) Oxygen Production Technology
Industrial oxygen production methods mainly include cryogenic air separation oxygen generation, vacuum pressure swing adsorption oxygen production and membrane separation oxygen production. VPSA is an advanced gas separation technology standing at an irreplaceable position in the field of gas supply. Main features of vacuum pressure swing adsorption oxygen plant are as follows:
Based on these characteristics, VPSA technology is more advantageous in variable and low-purity (80~94%) oxygen use due to low cost, easy operation, and flexible load adjustment compared with cryogenic oxygen production technology (large-scale oxygen with >95% purity).

Technology & Design Highlights
Lithium-Based Adsorbent and Airflow Distribution
VPSA-O2 Plant is built around high-efficient lithium-based VPSA-O2 adsorbent PU-8, selected to support oxygen enrichment performance at industrial scale. The system integrates unique airflow distribution technology to improve bed utilization and maintain stable separation behavior across cyclic switching. This combination supports energy-efficient oxygen generation and aligns with large-capacity plant design goals.
Double-Vessel Adsorber Architecture and Cyclic Switching
The adsorber is a double-vessel system to enable continuous oxygen production. Under PLC-based logic control, program-control valves control each vessel to alternate between adsorption and regeneration cycles. This design supports stable oxygen delivery while N2, CO2, and H2O are adsorbed from the incoming air stream.
Filtration, Blower, and Vacuum Regeneration
Mechanical impurities are removed from the air, which is then sent into the adsorption vessel by a blower. Once the adsorbent reaches saturation, a vacuum pump drives complete desorption for regeneration. This vacuum desorption step is foundational to maintaining repeatable separation performance and sustaining continuous operation cycles in industrial duty.
Process Engineering for Industrial Economics
The process design aligns with key economic metrics for oxygen production, featuring compact structure, automation readiness, and flexible load regulation. Power consumption is referenced as unit energy per 100% pure oxygen under defined design conditions, enabling consistent evaluation across operating points.
