Product Description
Low Energy VPSA Vacuum Adsorption Oxygen Production
The main components of air are nitrogen and oxygen. At normal temperature, zeolite molecular sieves (ZMS) exhibit different adsorption capacities for nitrogen and oxygen (oxygen passes through while nitrogen is adsorbed), enabling oxygen separation from air through proper design. Nitrogen adsorption capability is higher than oxygen adsorption capacity. When pressurized air passes through the adsorption tank filled with ZMS, nitrogen and only a small amount of oxygen are adsorbed, while most oxygen flows out of the tank, producing oxygen by separating nitrogen and oxygen.
When ZMS becomes saturated with nitrogen, the air supply stops and tank pressure is reduced, allowing nitrogen to be released from the ZMS, thus regenerating the molecular sieves for reuse. Two or more absorption tanks operating alternately enable continuous oxygen gas production.
This process requires a dedicated PD blower to compress the air stream for continuous operation and a dedicated vacuum blower for absorber regeneration. The VPSA process is more energy efficient due to its inherent continuous operation, making this technology ideal for large-scale, high-volume, low-pressure oxygen requirements.

Product Overview
VPSA (Vacuum Pressure Swing Adsorption) oxygen production equipment is a complete gas separation system that uses air as raw material to separate and produce oxygen through vacuum pressure swing adsorption technology. As an upgraded branch of pressure swing adsorption (PSA) oxygen production technology, this method originated from the air separation industry in the early 20th century. After decades of technological iteration, China's first industrial VPSA oxygen production equipment was put into use and has now developed into a mature industrial oxygen production solution widely applied in metallurgy, chemical industry, environmental protection, glass manufacturing, medical healthcare, aquaculture, and other fields, meeting oxygen supply needs across various industrial scales and special scenarios.
Core Working Principle
- Raw material pretreatment: External air is first filtered to remove dust and impurities, then pressurized to the required process pressure by a Roots blower, cooled by a cooler, and sent to the adsorption tower.
- Adsorption separation: The adsorption tower employs a double-layer bed structure design, with the lower layer filled with activated alumina to remove moisture and carbon dioxide from the raw air, protecting the upper molecular sieve. The upper layer contains high-performance lithium-based molecular sieves that selectively adsorb nitrogen and residual impurities. Oxygen is enriched at the top of the tower and transported to the oxygen balance tank for storage and output.
- Vacuum desorption regeneration: When molecular sieves in the adsorption tower reach saturation, the system switches working states through a switching valve, and the saturated adsorption tower is vacuumed by a vacuum pump. Impurities such as nitrogen, water, and carbon dioxide are extracted and discharged into the atmosphere, restoring the molecular sieve's adsorption capacity.
- Circulating continuous oxygen production: The equipment features two or more adsorption towers with valve switching automatically controlled by the control system to alternately complete the complete cycle of "adsorption-desorption-stamping," achieving all-weather continuous and stable oxygen supply.
Product Technical Advantages
- Lower energy consumption and operating costs: VPSA technology operates at low pressure and utilizes efficient lithium-based molecular sieves and power systems, achieving industry-leading comprehensive power consumption. Compared to traditional cryogenic air separation processes, it saves 20%-30% energy, with some scenarios achieving over 40% energy savings. Larger equipment scales yield lower unit energy consumption, demonstrating outstanding economies of scale.
- Simple process flow and flexible startup: The entire process operates at room temperature without complex low-temperature equipment and insulation systems, resulting in shorter construction periods. The device starts quickly, reaching rated oxygen production within tens of minutes. Load adjustment is flexible, allowing oxygen production to be adjusted according to demand, adapting to fluctuating requirements across different production scenarios.
- High automation and low maintenance costs: Utilizes fully automatic control systems enabling unmanned operation, reducing manual input. Core dynamic equipment includes oil-free volumetric blowers and vacuum pumps with simple structures, easy maintenance, and significantly lower maintenance costs than traditional oxygen production processes.
- Flexible scale and adjustable purity: Wide product coverage with flexible customization from small to large-scale oxygen production. Oxygen purity can be adjusted within the 30%-95% range according to demand, meeting differentiated purity requirements across various industries.
- High safety and environmental friendliness: The entire oxygen production process involves physical separation without high-pressure or high-temperature chemical reactions, no toxic or harmful material emissions, ensuring safe and stable operation while meeting modern industrial environmental requirements.
Application Fields
- Metallurgical and steel industry: Used for oxygen-enriched ironmaking and converter steelmaking with oxygen-enriched combustion assistance, improving smelting efficiency, reducing energy consumption, and decreasing pollutant emissions. Multiple large-scale VPSA oxygen production units have been stably applied in domestic production scenarios.
- Glass and cement manufacturing: Oxygen-enriched combustion increases combustion temperature, reduces fuel consumption, decreases smoke emissions, and improves product yield and production efficiency.
- Environmental water treatment: Used for biochemical aeration in sewage treatment. Compared to traditional aeration methods, it improves water treatment efficiency and reduces operating costs. Also applicable to oxygen-enriched incineration processes for waste incineration.
- Chemical industry and aquaculture: Provides process oxygen for chemical production and enables high-density aquaculture water oxygenation to increase aquaculture yield.
- Vehicle and medical healthcare: With mass production of automotive-grade VPSA oxygen production technology, applied to high-end vehicle oxygen production systems supporting dispersed whole-vehicle oxygen enrichment and nasal suction high-concentration oxygen supply, meeting high-altitude travel and healthcare needs, and suitable for small to medium-sized medical oxygen production.
