VPSA-O2 and equipments Technical:
Oxygen is one of the important industrial gasses, which is used widely in steel and iron industry, colored metallurgy, chemical industry, energy conservation in kiln stoves, environmental protection (sewage treatment, trash burning and so on), glass, paper making, medicine and so on. With the emergence of lithium molecular sieve absorbent in 1990s, the technique of air adsorption and separation under live pressure and oxygen manufacture has been developing rapidly as a new technique of low cost and has been used widely since then.
Based on its independently developed and produced lithium-based absorbent for air separation and oxygen manufacture PU-8, which is new and highly effective and of international advanced level, Peking University Pioneer Science & Technology Co. Ltd. Attached to Beijing University has successfully developed the technique of air adsorption and separation under live pressure and oxygen manufacture and the unique technique of air current spreader design as well, which has solved the problem of air current distribution uniformity in shallow adsorbing bed of large diameter and realized the production of oxygen manufacture installment of large scale. This technique has won the First Award of Advancement in Science and Technology by Education Ministry in 2006.
According to the user's requests, Peking University Pioneer Science & Technology Co. Ltd. Can provide the technique of air adsorption and separation under live pressure and oxygen manufacture and its complete set of equipment, or cooperate with the user in the way of renting equipment, providing gas for them on the spot and so on. And we can also carry on the technological transformations for the oxygen manufacture equipment that the user has with the highly effective absorbent for air separation and oxygen manufacture PU-8.

Energy consumption in oxygen manufacture: 0.32~0.37KWh/Nm3 when oxygen purity is 90%.
Technical characteristics and their advantages:
Low energy consumption in oxygen manufacture: The electricity consumption is 10~30% lower compared with the domestic similar technology.
Simple operation, convenient starting and stopping (starting time is shorter than 30 minutes), taking small area, low maintenance cost, low installment and construction expense.
Advanced technical process, high automaticity, big operation elasticity, high reliability in the long-term operation.
Beijing Peking University Pioneer Technology Co. Ltd (shortly called PIONEER) is engaged in research & development of PSA (pressure swing adsorption) technology, design & construction of PSA facilities and high efficiency adsorbents and catalysts.
The VPSA-O2 separation technology of PIONEER won the 1st Class Science and Technology Progress Medal awarded by the Ministry of Education of China in 2006 and the VPSA-CO separation technology won the 2ND Class National Technology Invention Award of China in 2007. PIONEER has already strengthened its position as world leader in this field of technology.
Since founded in 1999, over 100 PSA Plants, including the world's largest units-single set of VPSA-CO and VPSA-O2 equipments, have been designed and supplied by PIONEER. These PSA systems are suitable for the most different applications in the chemical industry, steel, non-ferrous metals, glass, paper manufacturing, sewage treatment, etc.
At present, our state-of-art techniques and products have been exported to US, UK, Spain, South Korea, Thailand and some other counties.
