Industrial PSA Oxygen Production Plant
The Industrial PSA Oxygen Production Plant utilizes Pressure Swing Adsorption technology to separate oxygen from ambient air. Using high-grade Zeolite Molecular Sieves (ZMS), the system selectively adsorbs nitrogen under pressure to continuously deliver high-purity gaseous oxygen. Designed for continuous industrial and medical operations, the plant integrates air compression, filtration, adsorption towers, and surge tanks into a skid-mounted, factory-tested unit.

Key Features
Dual-Tower Adsorption Cycle: Alternating adsorption and regeneration phases ensure uninterrupted oxygen output.
Automated Purity Control: Integrated zirconia/electrochemical analyzers continuously monitor purity, automatically venting off-spec gas.
Pneumatic Switching Valves: Heavy-duty process valves rated for > 1,000,000 switching cycles without maintenance.
PLC Control Interface: Siemens/Allen-Bradley PLC paired with an industrial HMI for automated startup, pressure regulation, and fault logging.
Energy Recovery System: Optimized piping geometry minimizes internal pressure drop, reducing specific power consumption per Nm3.
Applications
Healthcare Facilities: Central pipeline supply for hospitals, clinics, and emergency field stations.
Metal Fabrication: Oxy-fuel cutting, welding, and laser-assist gas supply.
Environmental Engineering: Pure oxygen injection for high-load wastewater treatment aeration basins.
Aquaculture: High-density fish farming and recirculating aquaculture systems (RAS).
Glass & Mineral Processing: Furnace enrichment to increase flame temperature and thermal efficiency.
Customization Options
Containerized Enclosures: ISO-certified weatherproof and sound-attenuated container packages for outdoor installation.
High-Pressure Filling Systems: Integrated multi-stage oxygen booster compressors for cylinder filling (up to 150 bar).
Dew Point Suppression: Refrigerated and desiccant air dryers tailored for humid tropical or sub-zero operating environments.
Redundant Configurations: Dual-train valve manifolds or backup liquid oxygen vaporization integration.
Manufacturing & Quality Control
Vessel Fabrication: Pressure vessels built strictly to ASME Section VIII or CE/PED standards, featuring automated submerged arc welding (SAW) and 100% radiographic weld inspection.
Sieve Loading Technique: Dense, vibration-assisted molecular sieve loading prevents channeling and premature bed attrition.
Factory Acceptance Testing (FAT): Every plant undergoes a 72-hour continuous full-load run test measuring power draw, flow stability, and purity output prior to crating.

ASME U Stamp certified pressure vessels available.
CE / PED 2014/68/EU compliance for European pressure equipment directives.
Electrical panels compliant with UL / CSA or IEC standards.
Packaging & Delivery
Modular Skid Design: Base-frame mounted units designed for standard 20ft/40ft open-top shipping containers.
Protective Prep: Flanges sealed with blind covers; delicate instruments removed and packed in shock-absorbing export crates.
Documentation Package: Includes P&ID drawings, electrical schematics, material test reports (MTRs), and FAT certificates.
FAQ
Q: What is the typical lifespan of the Zeolite Molecular Sieve (ZMS)?
A: Under proper feed air filtration meeting ISO 8573-1 standards (oil and moisture free), the ZMS operates for 8 to 12 years before requiring replacement.
Q: How does ambient humidity affect plant output?
A: High inlet humidity increases the load on the air preparation train. Our systems integrate strict ISO 8573-1 air quality controls and are sized using local peak psychrometric data to maintain rated output at 45C ambient.
Q: Can the system integrate with an existing backup manifold?
A: Yes. The PLC includes auxiliary dry contacts and Modbus/TCP communication protocols for automated switchover to backup liquid cylinders.
