Ⅰ. Equipment Description Basic principle of pressure swing adsorption (PSA) oxygen production: Raw air is filtered to remove impurities through the blower inlet filter before entering the blower. After being pressurized by the blower, it enters the adsorbent bed via pipelines and pneumatic switching valves. Moisture and carbon dioxide in the raw air are adsorbed by PU-8/TS adsorbent....

China’s pressure swing adsorption (PSA) oxygen production technology originated in the 1970s. After decades of development, the technology has been continuously upgraded, and high-efficiency lithium-based molecular sieves for oxygen production have been industrialized and widely applied. Latest research in the field shows that optimizing adsorbent manufacturing, improving adsorption tower d...

The biggest challenge facing oxygen-enriched blast furnace operation is oxygen supply. Instability in the oxygen enrichment rate of blast furnaces at integrated iron and steel works has long been a critical issue, which is highly detrimental to the stability of blast furnace conditions and the performance of coal injection. Practical Challenges A Chinese iron and steel enterprise commissione...

In response to the call from the Ordos municipal government to promote the translation and implementation of Peking University's scientific and technological achievements in Ordos, and leveraging the University's profound research heritage along with its own industrial capabilities, Peking University Pioneer Technology Co., Ltd. (hereinafter “PKU Pioneer”) was invited as a core t...

Based on the nature of interactions between adsorbates and adsorbents, adsorption can be classified into chemical adsorption and physical adsorption. Chemical Adsorption Chemical adsorption refers to the adsorption process accompanied by chemical reactions.During chemical adsorption, adsorbate molecules react with the surface of adsorbents to form surface complexes, and the adsorption heat is...

Recently, the second-phase 14,000 Nm³/h pressure swing adsorption (VPSA) oxygen generation facility, constructed by Beijing Peking University Pioneer Technology Co., Ltd. (hereinafter referred to as "PKU Pioneer") for Chifeng Yuanlian Iron and Steel Co., Ltd. (hereinafter referred to as "Chifeng Yuanlian"), has successfully commissioned and achieved stable oxygen supply. ...

This is the 18th successive year that PKU Pioneer has obtained the qualification. The High and New Technol...

In March 2023, PKU Pioneer won the bid for an oxygen plant project (5,054Nm3/h, ≥93%) to support the fiberglass pool kiln drawing production line with an annual output of 150,000 tons for a well-known domestic fiberglass manufacturer. In recent years, PKU Pioneer has designed and constructed 3 VPSA oxygen generation plants for this client. And the long-term stable operation and e...

On March 18, the energy-saving and emission-reduction technological upgrading project of Chifeng Fubang Copper Co., Ltd., a subsidiary of CNMC, held a grand opening ceremony in Linxi Prefecture, Chifeng. It is a technical renovation project for the old factory, making it necessary to make full use of the existing facilities and land. A new smelting plant will be set up for the smel...

In June 2023, PKU Pioneer successfully reached a cooperation agreement with Benxi Shentie Iron (Group) Co., Ltd (hereinafter referred to as Shentie Group) on the consecutive two-phase construction of a 4000Nm3/h VPSA oxygen plant project. Although PKU Pioneer has built a number of oxygen systems for foundry blast furnace oxygen enrichment, it is the first case in the castin...
