the second-phase 14,000 Nm³/h pressure swing adsorption (PSA) 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.

Peking University Pioneer is one of the earliest high-tech enterprises established in China specializing in pressure swing adsorption air separation oxygen generation and carbon monoxide separation. It has significant advantages in the number of projects and engineering experience, and owns core technologies with independent intellectual property rights - high-efficiency oxygen generation adsorbents and high-efficiency carbon monoxide adsorbents. It has vigorously promoted the large-scale and low-energy consumption development of China's pressure swing adsorption oxygen generation technology, as well as its pioneering application in multiple emerging fields, leading the localization substitution of China's pressure swing adsorption oxygen generation technology and promoting China to become the country with the deepest and most extensive application of this technology.

Project Background & Drivers: A chemical enterprise in Shandong faced long-term issues with its 100,000-ton/year butanol-octanol production line’s supporting PSA-CO unit. Problems included failure to meet designed capacity, high CO gas impurity levels, and unstable downstream synthesis, despite previous adsorbent replacement attempts. To address these bottlenecks, the enterprise launched a technical retrofit in August 2025 and selected PKU Pioneer for its proven expertise in complex CO separation scenarios.

On July 24, 2025, the China General Machinery Industry Association organized a product appraisal meeting in Beijing for the “Third-Generation PU-8 Lithium-Based Molecular Sieve Low-Energy Four-Tower Radial-Bed Pressure Swing Adsorption Oxygen Generation Equipment” developed by Beijing Peking University Pioneer Technology Corporation Ltd.The appraisal committee unanimously agreed that the performance indicators of the “Third-Generation PU-8 Lithium-Based Molecular Sieve Low-Energy Four-Tower Radial-Bed Pressure Swing Adsorption Oxygen Generation Equipment” developed by Beijing Peking University Pioneer Technology Co., Ltd. have reached the internationally advanced level and recommended its widespread adoption.

PKU Pioneer has designed and constructed over 400 medium-to-large-scale VPSA oxygen generation projects worldwide for industries such as steel, non-ferrous metal smelting, glass furnaces, cement, pulp bleaching, and lithium batteries. With world-leading technological expertise, we provide advanced oxygen production solutions to help customers achieve cost-efficient oxygen supply.

The operating cost of the VPSA-O₂ system is significantly more economical compared to liquid oxygen. It can effectively reduce the company's oxygen usage costs, decrease capital investment, enhance the company's financial risk resilience, and improve the advanced nature and market competitiveness of the Ozone Catalytic Oxidation technology for treating high-salinity wastewater. The VPSA-O₂ system's process technology offers advantages such as intelligent automation, flexible oxygen load adjustment, and high adaptability to ozone, making it particularly suitable for the process requirements of ozone generators and achieving optimal ozone production results.
