VPSA-O2 Plant
Large-Scale, Energy-Efficient Oxygen Production
Vacuum Pressure Swing Adsorption is an advanced gas separation technology that uses the different selectivity of adsorbents for gas molecules. PIONEER VPSA-O2 units use the proprietary PU-8 adsorbent to enrich oxygen from ambient air and supply it directly to industrial users.
PIONEER has built more than 100 VPSA-O2 plants in China, including some of the world’s largest systems. The technology combines independently developed adsorbent, airflow distribution, process engineering and mature auxiliary equipment.

Technology Brief
A VPSA-O2 system adsorbs nitrogen and other gas molecules under pressure, enriches oxygen for downstream use and regenerates the adsorbent under vacuum. The process supports continuous oxygen supply with flexible load adjustment.
Application Range
VPSA-O2 plants support oxygen-rich coal injection and electric-furnace steelmaking, non-ferrous metallurgy, chemical production, glass and cement kilns, waste incineration, pulp bleaching and wastewater treatment.
