Application of VPSA-O₂ and Ozone Catalytic Oxidation Coupling Process in High-Salt Chemical Wastewater Treatment Technology

In ozone generation processes, pure oxygen or oxygen enrichment is commonly used as feedstock. Oxygen sources typically include physical separation methods (such as Vacuum Pressure Swing Adsorption oxygen generation (VPSA-O₂) and cryogenic distillation) and chemical reaction-based production. Among these, VPSA-O₂ systems offer mature technology, high safety/reliability, advanced automation, and unmanned operation capabilities.

A petrochemical base in Jiangsu implemented a high-salinity wastewater treatment project (Phase I) with capacity of 12,000 t/d. The oxygen demand reaches 96,000 m³/day, supplied through both liquid oxygen systems and VPSA-O₂ systems. PKU Pioneer designed two dual-tower VPSA-O₂ units for this facility. Each unit comprises blowers, vacuum pumps, dual-shaft motors, adsorber vessels, heat exchangers, oxygen compressors, and auxiliary equipment. The two adsorber vessels operate alternately in oxygen production and vacuum desorption modes, achieving continuous operation through intelligent switching.

PKU Pioneer delivered VPSA-O₂ systems with a total output of 2×2,000 m³/h (92% purity), including oxygen generation and oxygen compressor..

In the high-salinity wastewater treatment project (Phase I), the daily oxygen consumption is 96,000 m³. If liquid oxygen is used for supply, with about 700 m³ of oxygen produced per ton of liquid oxygen, the daily consumption of liquid oxygen is approximately 137.1 tons, and the annual oxygen consumption is about 45,243 tons (with an annual operation period of 330 days). The annual procurement price range of liquid oxygen is about 500-700 yuan (CNY) /ton, and can reach up to 900 yuan /ton at its peak. The average annual procurement cost (at a unit price of 600 yuan /ton) is about 27 million yuan . Liquid oxygen needs to be ordered well in advance, and its price is greatly affected by market supply, which significantly impacts the company's production operations and creates substantial financial cost pressure. During peak periods of liquid oxygen demand, procurement is difficult and costly, which is unfavorable for the stable treatment and operation of high-salinity wastewater.

For the VPSA-O₂ system, all equipment including the oxygen generation unit, oxygen compression unit, and auxiliary facilities consumes a total of about 50,000 kWh of electricity per day, with an electricity cost of about 0.65 yuan /kWh. The annual operating cost is about 10.7 million yuan(with an annual operation period of 330 days), and the annual maintenance and equipment depreciation costs are about 1.5-2.5 million yuan. Compared to liquid oxygen, the VPSA-O₂ system can save about 13 million yuan in annual comprehensive operating costs, demonstrating significant economic benefits. At the same time, it is not affected by the price fluctuations of liquid oxygen supply, significantly reducing the company's financial risks.

In summary, the operating cost of the VPSA-O₂ system is significantly more economical compared to liquid oxygen, with annual savings of about 13 million yuan (CNY). 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.

The application of the VPSA-O₂-O₃ coupling technology in high-salinity wastewater treatment is mature, stable, and offers strong economic advantages. It has significant practical value for treating high-salinity wastewater, improves water resource utilization, and promotes sustainable economic and social development.

Analysis of VPSA Oxygen Production Technology: Process Comparison of Axial and Radial Adsorber Vessels

Adsorber Vessels are critical components in pressure swing adsorption oxygen generation systems, in the structural design of adsorber vessels, ensuring both high efficiency and long service life are the two primary objectives.

Currently, conventional adsorber vessel predominantly adopts an axial-flow packed adsorption bed structure (also known as axial flow). The advantages of this design lie in its simple construction and low manufacturing costs. However, it suffers from significant drawbacks, including strong gas flow impact during intake and exhaust, large vessel dead space, bulky equipment size, and stringent requirements for gas distribution calculations. Due to the excessively large diameter of such adsorber vessels,calculating the distributor's or***ce plate is challenging : if the plate is too thin, rigidity is compromised; if too thick, it becomes economically inefficient. The frequent cycles of pressurized intake and vacuum exhaust induce vibrations in large-diameter or***ce plates, leading to the wire mesh loosening, rupture, and subsequent molecular sieve pulverization and fluidization. Consequently, this axial-flow design significantly increases the risk of premature molecular sieve degradation. This issue is prevalent in pressure swing adsorption (PSA) oxygen generation systems using axial adsorber vessels, contributing to their limited operational lifespan.

PKU Pioneer’s vacuum pressure swing adsorption oxygen generation systems predominantly adopt radial adsorber vessel structure for medium and large-scale installations, where air flows from the outer to the inner side of the tower along the radial direction. This configuration minimizes impact on the molecular sieve, ensuring more uniform and stable gas distribution. Radial adsorber vessel offers multiple advantages, including compact size, reduced vessel dead space, lower pressure drop, and excellent gas distribution during both adsorption and desorption phases. Even under frequent gas intake and exhaust cycles, the bed remains highly stable, drastically reducing the likelihood of wire mesh loosening, rupture, or molecular sieve pulverization and fluidization. Additionally, the structural design of radial adsorber vessels ensures full contact between the molecular sieve and incoming air. With a thinner adsorption bed layer, the radial-flow system requires less molecular sieve for the same oxygen production capacity while achieving higher adsorption efficiency, stable output, and consistent purity.

The picture shows Axial and Radial Adsorber Vessels.

In 2013, PKU Pioneer developed its first radial adsorber vessel pressure swing adsorption (PSA) oxygen generation device, which was successfully commissioned in a single attempt, supplying 93% pure oxygen to a leading Chinese fiberglass enterprise. The project has been operating stably for over 12 years, demonstrating that the stability and service life of PKU Pioneer's radial adsorber vessel PSA oxygen generation technology have reached world-leading standards.

Since the successful industrialization of radial adsorber vessel, PKU Pioneer has exclusively employed this design in all its PSA oxygen generation systems. The company has executed over 400 large-scale PSA oxygen projects, with single-unit capacities reaching up to 100,000 Nm³/h, serving industries such as blast furnace oxygen enrichment, electric arc furnace steelmaking combustion support, full-oxygen glass furnace combustion, pulp oxygen delignification, and cement kiln oxygen enrichment. PKU Pioneer’s systems have been exported to more than 20 countries, including India, Russia, Brazil, Italy, and Germany, establishing the company as China’s most experienced and accomplished provider of large-scale industrial PSA oxygen generation solutions.

In (Vacuum Pressure Swing Adsorption) oxygen generating process adopting radial adsorber, air enters from the bottom of the adsorption vessel and crosses the adsorbent bed along from the vessel wall in radial flow. The is enriched in the middle of the adsorber and then stream into the buffer tank for the end use.

The technical principle of / oxygen generation technology is that when air passes through the adsorbent bed under pressure, nitrogen is adsorbed by the molecular sieve while oxygen is enriched and flows out of the bed, thereby separating oxygen from the air. When the molecular sieve is nearly saturated, the ventilation is stopped and a vacuum pump is used to lower the pressure of the adsorbent bed, as a result, the nitrogen molecules adsorbed by the molecular sieve can be desorbed and the molecular sieve is regenerated. The two adsorbent beds switch in turn to ensure constant generation.

Pioneer has designed and constructed over 400 large and medium VPSA gas separation and purification plants and projects, whose performance indicators have all reached the international advanced standard. Among them, the world's largest oxygen plant is designed and built by PKU Pioneer.

Pioneer Commissions 12,500 Nm³/h Oxygen Plant to Boost oxygen-enriched copper smelting

Recently, Pioneer successfully commissioned 12,500 Nm³/h vacuum pressure swing adsorption ( ) oxygen plant for Xinjiang Copper Co., Ltd. (hereinafter referred to as " Copper"), effectively addressing the plant's oxygen supply deficit and significantly enhancing its cathode copper capacity. The official commissioning of this project signifies Wuxin Copper 's enhanced commitment to promoting the innovative application of cost-effective oxygen production technologies in non-ferrous metal smelting.

Prior to the project’s implementation, Copper relied heavily on costly liquid oxygen procurement due to insufficient cryogenic air separation capacity. This not only drove up smelting costs per ton of copper but also resulted in unstable oxygen supply, keeping the oxygen enrichment rate of the Ausmelt Furnace consistently below design levels and severely restricting production capacity. With the project in operation, oxygen production and cryogenic air separation formed a coordinated system, steadily increasing the company’s oxygen self-sufficiency and eliminating critical supply bottlenecks.

The newly deployed system utilizes advanced lithium-based molecular sieves with high nitrogen-oxygen adsorption selectivity, offering significant advantages in adsorption efficiency and energy consumption compared to conventional oxygen production methods. By carrying out a "low-pressure adsorption, vacuum desorption" cycle, ( ) oxygen plant reduces energy consumption by over 40% compared to traditional cryogenic plants. Furthermore, the integration of oxygen compressor pressurization and cryogenic oxygen supply ensures stable, high-efficiency oxygen enrichment for the Ausmelt furnace while minimizing low-altitude emissions, thus achieving internationally advanced environmental performance.

Additionally, oxygen plant features a highly automated PLC control system and remote monitoring platform, greatly enhancing operational efficiency. The number of operators has been reduced by 60% compared to cryogenic plants, while the response time to equipment faults has been cut from 30 minutes to 5 minutes. This streamlined, intelligent upgrade aligns seamlessly with Copper’s digital transformation strategy.

According to statistics, as of July 2025, Pioneer has delivered nearly 100 VPSA oxygen plants for the non-ferrous metals industry, covering a wide range of production scales—from small (1,000–3,000 Nm³/h) and medium (3,000–8,000 Nm³/h) to large (8,000–30,000 Nm³/h) applications.

Moreover, in Indonesia, the world's largest oxygen production facility with a capacity of 100,000 Nm³/h was constructed for the non-ferrous metallurgy industry, setting a new global benchmark in the scale of industrial application of pressure swing adsorption ( ) oxygen production technology.
