Skid-Mounted Oxygen Production System
The Skid-Mounted Oxygen Production System is a modular, turnkey industrial gas generation plant utilizing Pressure Swing Adsorption (PSA) technology. Integrated onto a heavy-duty structural steel base frame, the system houses air compressors, refrigerated air dryers, multi-stage filtration banks, compressed air/oxygen surge receivers, and dual-tower PSA oxygen generators.
Factory pre-piped, pre-wired, and pressure-tested prior to shipment, this modular design eliminates complex on-site civil engineering and field assembly, allowing facilities to achieve rapid commissioning upon utility hookup.

Key Features
Modular Footprint: Structural carbon steel skid architecture reduces required plant floor space by up to 40% compared to conventional station layouts.
Rapid Cold Start: Reaches operational oxygen purity within 15 to 20 minutes from startup.
Automatic Purity Control (APC): Inline zirconia sensor continuously monitors oxygen concentration; sub-specification gas is automatically vented to protect downstream lines.
Pneumatic Process Valves: Heavy-duty, low-maintenance process valves rated for 1,000,000 switching cycles or more.
Optimized Energy Draw: Engineered molecular sieve packing density and automated pressure equalization cycles minimize specific power consumption per cubic meter of O2.
Applications
Metallurgy & Metal Fabrication: Oxy-fuel cutting, scrap steel melting in Electric Arc Furnaces (EAF), and specialized glass manufacturing.
Water & Wastewater Treatment: High-purity oxygen feed for biological municipal or industrial aeration tanks to accelerate chemical oxygen demand (COD) reduction.
Aquaculture: High-density fish farming and recirculating aquaculture systems (RAS) requiring stable dissolved oxygen (DO) levels.
Gold Mining: Carbon-in-leaching (CIL) and cyanidation recovery enhancement.
Healthcare: On-site central oxygen pipeline supply for regional clinics and field hospitals (complies with medical gas standards when paired with medical filtration trains).
Customization Options
Containerized Enclosures: Weatherproof, ISO-certified steel containers with integrated HVAC, fire suppression, and sound insulation for harsh outdoor or remote environments.
High-Pressure Cylinder Filling Station: Integration of a heavy-duty booster compressor and high-pressure manifold for filling 150 bar / 200 bar storage cylinders.
Explosion-Proof Configuration: ATEX/IECEx certified electrical components, instrumentation, and purge systems for hazardous oil, gas, or chemical plant zones.
Dual-Line Redundancy: Parallel compressor-generator trains for continuous 24/7 manufacturing plants requiring zero downtime.
Manufacturing & Quality Control
Structural Preparation: Skid frames undergo shot-blasting to Sa 2.5 standard, followed by an epoxy zinc-rich primer and polyurethane topcoat to resist industrial corrosion.
Pressure Vessel Compliance: Air and oxygen receivers manufactured to ASME Section VIII Div. 1 or PED 2014/68/EU standards; welded seams undergo 100% radiographic (RT) or ultrasonic (UT) non-destructive testing (NDT).
Piping & Cleanliness: All stainless steel process pipelines undergo acid pickling and passivation to remove oil residues, securing oxygen service safety.
Factory Acceptance Testing (FAT): Every skid undergoes a continuous 72-hour full-load runtime test measuring gas flow, power draw, dew point, and purity stabilization before crating.
Certifications & Compliance
Quality Management: ISO 9001:2015 certified manufacturing facility.
Pressure Safety: ASME U Stamp / PED CE certification available for pressure vessels.
Electrical Safety: CE compliant control panels with UL/CSA rated components available upon request.
Packaging & Delivery
Export Crating: Fumigation-free wooden crates or heavy-duty shrink-wrapped open-frame securing for container shipping (20'GP, 40'HQ, or Open Top).
Component Protection: Instrumentation ports sealed with threaded plugs; desiccant bags placed inside electrical cabinets to prevent humidity damage during ocean transit.
Documentation Package: Includes piping and instrumentation diagrams (P&ID), electrical schematics, PLC source code backup, NDT test reports, and English user manuals.
FAQ
Q: What is the expected lifespan of the zeolite molecular sieve?
A: Under stable operating conditions with proper oil and moisture filtration (maintaining dew point -40 deg C or lower and oil content less than 0.003 mg/m3), the molecular sieve operates for 6 to 8 years before replacement is required.
Q: How does ambient temperature affect system performance?
A: Standard units are rated for ambient operating temperatures between +5 deg C and +45 deg C. For extreme climates, optional ambient heating or tropical cooling packages are integrated into the skid.
Q: Can the system integrate into an existing plant SCADA network?
A: Yes. The Siemens PLC controller supports standard industrial communication protocols including Modbus RTU, Profinet, and Ethernet/IP for remote monitoring.
