The iron and steel industry could be affected by various factors such as the fluctuation of raw material prices, policy impacts, environmental protection policies, international trade barriers, supply and demand of downstream products, macroeconomic development and other integrated factors, so a considerable portion of the iron and steel enterprises set their sights on those technologies that could bring about a rapid increase in production capacity in the context of strict production capacity control, replacement of equal amount and elimination of outdated technologies. Among them, increasing the oxygen enrichment rate of blast furnaces is very realistic and effective. A considerable number of iron and steel enterprises have chosen to expand their oxygen production capacity, and have invested in building several sets of large-scale VPSA oxygen units.

PKU Pioneer has devoted itself to VPSA (Vacuum Pressure Swing Adsorption) and PSA (Pressure Swing Adsorption) technologies for nearly 25 years. With several innovations and iterations, its VPSA and PSA oxygen generation technology has been developed at the top level of the world, making it the world champion in this industry. The highest oxygen production capacity of PKU Pioneer's oxygen equipment in a single mill has reached 100,000Nm3/h, which is a breakthrough in the application of super-large VPSA oxygen units. PKU Pioneer is constantly expanding the forefront of the application of oxygen generation technology. Its oxygen generation systems have been successfully applied in lithium batteries, refractory materials and other fields, and effectively help the customers to improve their economic benefits.

PKU Pioneer, as a professional brand in VPSA and PSA industry, developed PSA-CO and PSA-H2 purification technologies. The low-carbon utilization technologies are developed upon the basis of its air separation processes.

On September 20, 2023, the Lonshi mining, processing and smelting integrated project (Congo Lonshi Copper Project) built by JCHX Mining Management Co., Ltd. in Democratic Republic of the Congo (DRC) in Africa was successfully completed and formally put into production. All the units involved held a grand commissioning ceremony in the electrowinning workshop of the project.

The patent of PKU Pioneer’s exclusive invention- Method for Designing Radial Bed with High Efficiency Airflow Distribution and Radial Bed Thereof was granted by the Indian Patent Office.

On October 26, 2023, according to the China High and New Technology Enterprise Evaluation Management Leading Group Office, 2,962 enterprises including PKU Pioneer were listed in the 2nd batch of Beijing High and New Technology Enterprises and got the recognition. This is the 18th successive year that PKU Pioneer has obtained the qualification.
