On December 10, 2023, 2 sets of VPSA oxygen plants (5556Nm³/h, 90%) built by PKU Pioneer for Gansu Jinchuan Group were successfully started up to provide stable oxygen for nickel flash smelting furnace and copper synthesis furnace.

PKU Pioneer hereby launches the steel industry promotional video (2023 new version)! PKU Pioneer has been promoting the application of VPSA (Vacuum Pressure Swing Adsorption) and PSA (Pressure Swing Adsorption) oxygen generation technology, low-carbon utilization technologies of steel exhaust gases, and dry fine desulfurization technologies in the steel sector. Driven by the "dual-carbon" strategy, and to create a low-carbon future, PKU Pioneer will be given unlimited opportunities to lead us to march forward together with the world's iron and steel enterprises!

1) Economically, VPSA oxygen-generating equipment has smaller investments and lower operation costs.

From the steel industry’s point of view, the government has divided the entire 2070 carbon neutral plan into three broad categories. Focusing on the short term – until 2030 – the Indian government has decided to promote energy efficiency in the steel industry and encourage steel producers to emphasize resource efficiency and renewable energy for a sustainable future. For the medium term – between 2030 and 2047 – the focus area could be green hydrogen and carbon capture, utilization, and storage. For the long-term perspective – between 2047 and 2070 – disruptive alternative technological innovations are the primary focus that can help achieve the transition to net zero.

Beginning stage: In the early 1970s, the US Union Carbide Corporation industrialized oxygen production by PSA technology for the first time. in the mid-1970s, the vacuum pressure adsorption (VPSA) oxygen production process was proposed, which greatly improved the scale and the economy of the oxygen plant, laying the foundation for the large-scale popularization and application of the VPSA oxygen production technology.

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.
