PSA Oxygen Plant (Pressure Swing Adsorption Oxygen Generator) is a core oxygen supply equipment for chemical oxidation reactions. Based on pressure swing adsorption technology and adopting a modular design, it can produce oxygen with a flow rate of 500Nm³/h and a purity of 93-95%, featuring core advantages of flexible flow rate, stable purity, corrosion resistance, and easy capacity expansion. As a mainstream industrial model of psa technology for oxygen generation, it can accurately meet the strict requirements for oxygen flow rate and purity in chemical oxidation reactions (e.g., methanol oxidation, ethylene oxidation, aromatic hydrocarbon oxidation). The modular design supports capacity expansion on demand, significantly reducing the initial investment and operating costs of chemical enterprises, making it an ideal oxygen supply choice for oxidation reactions in the chemical industry.

Chemical oxidation reaction is a core process in fine chemicals and petrochemicals. It produces various chemical products (e.g., acetaldehyde, acetic acid, ethylene oxide) through oxidation reactions between oxygen and raw materials. The flow rate, purity, and stability of oxygen directly affect reaction efficiency, product yield, and safe production. The production scale of chemical enterprises varies significantly: small and medium-sized enterprises (annual output of 10,000-50,000 tons) require an oxygen flow rate of 500-1000Nm³/h, while large enterprises need more than 1000Nm³/h. Additionally, some enterprises have phased capacity expansion needs.
The modular design of the PSA Oxygen Plant perfectly addresses this demand: a single module with a flow rate of 500Nm³/h adapts to the initial production capacity of small and medium-sized enterprises. For subsequent capacity expansion, 1-3 modules can be directly added to quickly increase the flow rate to 1000-2000Nm³/h. Compared with traditional integrated oxygen generators, the expansion cost is reduced by more than 40%, and the expansion process does not affect existing production. The oxygen purity of 93-95% can accurately match the requirements of oxidation reactions, with a purity fluctuation of ≤±1%, avoiding incomplete reactions or increased by-products caused by insufficient purity, and ensuring the product yield remains stable above 90%.
As a modular model of pressure swing adsorption oxygen generator, it has significant operating cost advantages. The unit energy consumption of 0.39kWh/Nm³ is 25-30% lower than that of traditional cryogenic oxygen generators. Calculated based on 8000 hours of annual operation, it can save hundreds of thousands of yuan in electricity fees every year, optimizing psa oxygen plant cost.
Chemical workshops have corrosive media and explosion-proof requirements, so the installation of PSA Oxygen Plant must focus on corrosion resistance and safety.
- Installation location: Choose a well-ventilated area away from reaction kettles and corrosive medium storage areas. The equipment foundation is cast with anti-corrosion concrete, and the surface is coated with anti-corrosion paint.
- Safety measures: The main body of the equipment must be grounded with a grounding resistance of ≤4Ω. The electrical system complies with the Ex d IIB T4 explosion-proof standard to avoid safety accidents caused by electric sparks.
- Pipeline installation: Oxygen pipelines are made of 316L stainless steel with good corrosion resistance. Pipeline connections adopt flange sealing, and gaskets are made of corrosion-resistant PTFE material to prevent oxygen leakage and pipeline corrosion. After installation, pressure testing (test pressure is 1.5 times the working pressure) and helium leak detection should be carried out to ensure no pipeline leakage.
The corrosiveness of chemical working conditions and continuous operation place higher requirements on the service life of the PSA Oxygen Plant. Scientific maintenance strategies can extend the equipment service life to 8-10 years.
- Anti-corrosion maintenance: Regularly inspect the anti-corrosion coating of the equipment shell and pipelines. If peeling or corrosion occurs, touch up the anti-corrosion paint in a timely manner. Conduct corrosion testing on stainless steel pipelines annually and replace them promptly if problems are found.
- Molecular sieve maintenance: Regularly inspect adsorption performance and conduct purity testing every six months. If purity decreases, perform regeneration treatment in a timely manner. Prevent corrosive gases from entering the adsorption tower and regularly replace the anti-corrosion filter element of the pretreatment system to ensure clean air intake.
- Maintenance of moving parts: For fans and valves (as moving parts), inspect lubricating oil levels and sealing status every quarter, conduct a comprehensive overhaul annually, and replace aging seals and bearings. Regularly calibrate sensors and actuators of the control system and back up parameters every six months to prevent data loss.
With its modular design, high adaptability, stability, and reliability, the PSA Oxygen Plant has become a flexible oxygen supply solution for chemical oxidation reactions. The 500Nm³/h single-module flow rate accurately matches the needs of small and medium-sized chemical enterprises. Its psa based oxygen plant technology can provide sufficient and stable oxygen support for oxidation reactions. Combined with standardized installation and scientific maintenance, it can help chemical enterprises improve product yield, reduce costs, ensure safety, and achieve sustainable development.
