Containerized PSA Oxygen Plant
The Containerized PSA Oxygen Plant is a fully integrated, factory-assembled industrial gas generation system housed inside a modified 20-foot or 40-foot ISO shipping container. Utilizing Pressure Swing Adsorption (PSA) technology with high-grade Zeolite Molecular Sieves (ZMS), the system extracts oxygen from ambient air onsite. It delivers a continuous supply of 93% +/- 3% oxygen purity at pressures up to 150 bar (via integrated booster). Engineered for direct plug-and-play field deployment, it bypasses the need for dedicated compressor rooms, external pipe racks, or complex civil construction foundations.

Key Features
Modular Skid Architecture: Air compressor, refrigerated dryer, filtration train, twin adsorption towers, surge tanks, and oxygen booster pre-wired and piped internally.
Heavy-Duty Process Valves: Pneumatic switching valves rated for >= 1,000,000 switching cycles without mechanical overhaul.
Automatic Purity Purging: Integrated zirconia oxygen analyzer continuously monitors output purity; off-spec gas is automatically vented prior to the storage tank.
Climate-Controlled Enclosure: Equipped with industrial HVAC units, louvered ventilation vents, and 50mm polyurethane sandwich panel thermal insulation.
PLC Control & SCADA Integration: Siemens S7-1200/1500 PLC with HMI touch screen supporting Modbus TCP/IP for remote plant monitoring.
Applications
Remote Mining Operations: Onsite supply for gold leaching and worker respiratory safety in high-altitude regions.
Healthcare Facilities: Primary or backup medical gas pipeline supply aligned with ISO 7396-1 standards.
Water & Wastewater Treatment: High-purity oxygen feed for ozone generators in municipal sewage and industrial effluent treatment.
Metal Fabrication & Glass Working: Fuel-gas assistance for heavy oxy-fuel cutting, welding, and ampoule manufacturing furnaces.
Customization Options
High-Altitude Adaptations: Oversized air compressors and adjusted cycle times to compensate for low barometric pressure (> 2,500m elevation).
Power Redundancy: Integrated diesel generator backup interface for off-grid operation.
Explosion-Proof Rating: ATEX / IECEx certified electrical components for Zone 2 hazardous classified environments.
Dual-Line Output: Simultaneous delivery of low-pressure process gas and high-pressure cylinder filling manifold.
Manufacturing & Quality Control
Vessel Fabrication: Adsorption towers built according to ASME Section VIII Div. 1 or PED 2014/68/EU codes, utilizing carbon steel Q345R or stainless steel 304.
Welding Standards: 100% radiographic (RT) and ultrasonic testing (UT) performed on high-pressure piping and pressure vessels by certified EN ISO 9606 welders.
Factory Acceptance Testing (FAT): Every unit undergoes a 72-hour continuous full-load run test measuring flow, power draw, and dew point stability prior to crating.
Certifications & Compliance
ISO 9001:2015 Quality Management System certified manufacturing facility.
CE Compliance: For electrical panels, Pressure Equipment Directive (PED), and machinery safety.
ISO 13485 :Compliance alignment for medical-grade oxygen production systems.
Packaging & Delivery
Shipping Unit: Built inside a standard CSC-certified ISO shipping container, allowing direct ocean freight booking without special flat-rack permits.
Internal Protection: Anti-condensation coating applied to container interior; equipment anchored to structural floor beams using anti-vibration mounts.
Documentation Package: Complete dossier supplied including material test reports (MTRs), welding logs, electrical schematics, and PLC source code backup.
FAQ
Q: What is the typical maintenance schedule for the molecular sieve?
A: Zeolite molecular sieve life exceeds 5 to 8 years under proper operating conditions. Maintenance is limited to replacing compressor air filter elements every 2,000 operational hours and checking coalescing filter drains.
Q: Can the container withstand extreme winter conditions?
A: Yes. The container walls incorporate 50mm polyurethane sandwich panel insulation, paired with internal electric duct heaters and thermostat-controlled exhaust fans.
Q: What utilities must be prepared on-site prior to delivery?
A: A leveled concrete foundation pad, a 3-phase industrial power supply drop, and a grounding rod grid. No permanent shelters or buildings are required.
