Technology Brief Based on the principle of VPSA technology, the VPSA-O2 units adopt the special adsorbent (model: PU-8) to enrich the oxygen in the air and supply it to the user. Production Capacity 1000Nm3/h~40000 Nm3/h, Converted to liquid oxygen: 34 TPD~1360 TPD Typical Applications > Steel: Blast furnace oxygen-rich coal injection, electric furnace steelmaking > Non-ferrous metallurgy: combustion-supporting for non-ferrous metals metallurgy including copper, lead, nickel, zinc, tin and gold. > Chemical: gasification furnace oxygen-rich gas making, carbon black production, sulphur trioxide production etc. > Kiln energy-saving: combustion supporting for glass kilns, cement kilns and oxygen-rich combustion supporting for waste incinerators > Papermaking: pulp bleaching process > Sewage treatment: OEAA technology, oxygen source for ozonizer Technical Advantages 1. Experienced engineering PKU PIONEER has built the most VPSA-O2 plants in China, including the world's largest VPSA-O2 plant. 2. Excellent energy consumption Energy consumption of PKU PIONEER's VPSA-O2 plant is 0.29-0.32kWh/m3 O2, which is among the lowest, around the world. 3. Internationally-leading process design PKU PIONEER has built up the first set of radial bed in China. Independently-developed five-bed, air intake and other original process designs have proved obvious advantages. 4. The independently-developed lithium-based adsorbent PKU PIONEER's independently-developed and produced lithium-based VPSA-O2 adsorbent PU-8 is featured by high selectivity and high working capacity of nitrogen, which is among the best around the world. 5. Mature and reliable system running The long-term engineering practice has proved that PKU PIONEER's VPSA-O2 plants are stable and the supplementary devices are mature and reliable, thus ensuring the continuous production for users.
