Oxygen Production Plant

Psa in Oxygen Plant produces oxygen based on the principle of selective adsorption using molecular sieves. Compressed and purified air enters an adsorption tower, where the molecular sieve absorbs nitrogen and releases oxygen under high pressure. Dual or multiple towers alternately adsorb and regenerate, ensuring a 24-hour stable oxygen supply. Key specifications include oxygen purity of 90%-99.5%, gas production capacity ranging from m³/h to 5000 m³/h, and operating pressure of 0.4-0.8 MPa (customizable for high-altitude applications). The system integrates multiple modules, offers high automation, a molecular sieve lifespan of 5-8 years, and low maintenance costs. Suitable for medical, industrial, and environmental protection applications, it is a promising alternative to traditional oxygen production for low-cost, stable oxygen supply.

PSA Oxygen Generator vs. Cryogenic Air Separation Oxygen Generator

Comparison Dimension	PSA Oxygen Generator	Cryogenic Air Separation Oxygen Generator
Oxygen Purity	Flexible range (90%-99.9%), customizable for most industrial/medical needs	Ultra-high purity (≥99.5%, max 99.999%), suitable for strict scenarios (aerospace, electronics)
Capacity Scale	Strong adaptability for small-medium capacity (0.5-5000Nm³/h), modular & easy to expand	Ideal for ultra-large capacity (5000-100000Nm³/h), low unit oxygen cost in mass production
Start-Up & Response	Fast start-stop (15-30 mins to stable output), supports frequent operation switches for intermittent use	High long-term stability (≥95% annual operation rate), 24/7 continuous operation once stable
Energy & Cost	Low energy consumption (0.4-0.8kWh/Nm³ O₂) for small-medium capacity; low initial investment; short construction period (3-6 months)	Low unit energy consumption (0.3-0.6kWh/Nm³ O₂) for ultra-large capacity; long core equipment life (15-20 years); low long-term operation cost
Application Scenarios	Fits small-medium scale, intermittent use, medium purity needs (small hospitals, food processing, wastewater treatment)	Fits large-scale, continuous, high-purity needs (large steel plants, energy chemicals, aerospace)

How to choose between cryogenic air separation and large-scale PSA oxygen production plants?

For high purity (≥99.5%) and ultra-large production capacity (>5000 Nm³/h), choose the cryogenic method; for medium-to-low purity and flexible start-up and shutdown, choose the PSA method.

How long does it take to build an oxygen production plant?

For a conventional scale (1000-3000 Nm³/h), the design to commissioning process takes approximately 8-12 months, including equipment manufacturing, installation, and commissioning.

How can energy costs be controlled during equipment operation?

With a waste heat recovery system, the cryogenic method can be integrated with power generation, and the PSA method optimizes the adsorption cycle, reducing overall energy consumption by 15%-20%.

What auxiliary equipment is required for an oxygen production plant?

It requires an air compressor, dryer, filter, oxygen storage tank, pressure regulating valve assembly, and safety monitoring system.

Is it possible to co-produce oxygen and nitrogen?
Supporting co-production of oxygen and nitrogen, the cryogenic method can simultaneously produce nitrogen with a purity exceeding 99.99%, meeting multi-gas demand scenarios.
