500Nm³/h Modular PSA Oxygen Plant for Chemical Oxidation Reactions
Product Description
The 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.

Oxygen Supply Requirements of Chemical Oxidation Reactions and Advantages of Modular PSA Oxygen Plant
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 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.
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.
Installation Methods and Anti-Corrosion Measures
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.
Key Strategies for Extending Equipment Service Life
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.
- Molecular sieve maintenance: Regularly inspect adsorption performance and conduct purity testing every six months. If purity decreases, perform regeneration treatment in a timely manner.
- Maintenance of moving parts: For fans and valves, inspect lubricating oil levels and sealing status every quarter, conduct a comprehensive overhaul annually, and replace aging seals and bearings.
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.
