High-Purity Industrial Oxygen Plant for Semiconductor and Medical Use

High-Purity Industrial Oxygen Plant is an advanced cryogenic air separation system designed for industries requiring continuous and reliable oxygen supply. By utilizing deep cryogenic distillation technology, the plant separates oxygen directly from atmospheric air and delivers stable oxygen purity from 99.5% to 99.999%.

Unlike conventional PSA oxygen generators, cryogenic oxygen plants are engineered for large-scale production with higher efficiency, longer operation cycles, and the capability to simultaneously recover nitrogen and argon. The system provides an independent oxygen source for semiconductor manufacturing, medical facilities, chemical processing, metallurgy, and energy industries.

◆◆ Key Applications ◆◆

1. Semiconductor Manufacturing:

• High-purity oxygen is essential for oxidation processes, etching, and chemical vapor deposition (CVD) in silicon wafer fabrication. In the precision-driven environment of microelectronics, even microscopic impurities can ruin an entire production batch. Our plant supplies the exact ≥99.999% purity required for these sensitive reactions. Recent deployments at leading global semiconductor foundries demonstrate a flawless track record, maintaining absolute gas consistency during continuous 24/7 production cycles and providing strong on-site proof of our equipment's reliability.Provides ultra-high purity oxygen for wafer oxidation, chemical vapor deposition (CVD), and advanced semiconductor fabrication processes where contamination control is critical.

2. Pharmaceuticals and Biotechnology:

• Supports sterile fermentation, cell culture processes, and the production of active pharmaceutical ingredients (APIs). The biological synthesis of delicate compounds demands absolute sterility and exact atmospheric control. This system provides a dependable oxygen source for these critical processes, verified by successful installations in major biopharma facilities across Europe and Asia, ensuring zero contamination risk for sensitive medical products.

3. Chemical and Petrochemical Industries:

• Used in oxidation reactions, synthesis of specialty chemicals (e.g., ethylene oxide), and catalyst regeneration. Heavy-duty chemical synthesis relies on massive volumes of reactive gas. The plant supports these intense oxidation reactions by delivering a stable, high-volume flow, proven in large-scale petrochemical refineries where operational uptime directly dictates the facility's overall profitability.

4. Medical and Healthcare:

• Produces medical-grade oxygen (99.95% purity) for hospitals, respiratory therapy, and life support systems. Life support networks cannot tolerate supply interruptions. Generating medical-grade oxygen at a strict 99.95% purity, our units serve as the primary lifeline for numerous large-scale metropolitan hospitals. The breathable gas produced is odorless, exceptionally clean, and strictly adheres to global pharmacopeia monographs.

5. Aerospace and Energy:

• Provides oxygen for rocket propulsion systems, fuel cell testing, and clean combustion in power generation. From clean combustion in advanced power generation to rigorous fuel cell testing, the aerospace sector demands energetic oxidizers without moisture or particulate matter. Our separation technology guarantees the ultra-dry, dense oxygen required for these extreme-environment applications.

6. Steel & Chemical Industry

• Supplies high-volume oxygen for blast furnace enrichment, basic oxygen furnace (BOF), and metal refining processes, improving combustion efficiency and reducing fuel consumption.

◆◆ Technology and Features ◆◆

1. Advanced Air Separation Methods:

• Cryogenic Distillation: The gold standard for high-purity oxygen, involving air liquefaction at cryogenic temperatures (-185°C) and fractional distillation to isolate oxygen. Operating at a profound -185°C, the cryogenic distillation column represents the pinnacle of molecular separation. The thick, frost-coated exterior of the primary vessel houses a complex array of precision-engineered trays, effectively liquefying ambient air and isolating oxygen molecules with absolute certainty.

2. Multi-Stage Purification:

• Post-distillation or adsorption processes include catalytic converters to remove residual hydrocarbons and moisture filters to achieve ultra-high purity (≥99.999%). Before reaching the final storage manifold, the gas passes through intensive catalytic converters and advanced moisture filters. This multi-stage scrubbing eradicates residual hydrocarbons and trace moisture, guaranteeing the final output consistently hits the strict ≥99.999% ultra-high purity threshold demanded by sensitive applications.

3. Modular and Scalable Design:

• Customizable configurations (e.g., skid-mounted, containerized) for efficient integration into existing facilities. We engineer these plants with a highly compact, skid-mounted architecture that drastically reduces your facility's footprint. We provide comprehensive civil engineering and pipeline routing guidance prior to delivery, ensuring rapid on-site deployment.

• Scalable output from 100 Nm³/h to 50,000 Nm³/h to match diverse industrial demands. Whether you run a specialized laboratory or a massive steel mill, the output capacities are precisely tailored to match your specific operational scale.

4. Energy Optimization:

• Heat recovery systems, turboexpanders, and variable frequency drives (VFDs) minimize energy consumption. At the heart of the system lies a commitment to mechanical excellence. We exclusively integrate internationally recognized components, including Siemens PLC control architectures, heavy-duty Atlas compressors, and premium-grade cryogenic valves, ensuring decades of reliable, vibration-free operation.

• Compatible with renewable energy sources for sustainable operations. When combined with our custom heat recovery systems, these top-tier parts minimize power draw and allow for integration with green energy grids.

5. Automation and Safety:

• Integrated PLC systems enable real-time monitoring, remote control, and predictive maintenance. The entire generation process is governed by an intelligent, automated brain featuring a glowing, intuitive touchscreen interface for instant performance tracking.

• Explosion-proof designs and oxygen-compatible materials prevent combustion risks. Constructed entirely from specialized alloys, the plant actively mitigates fire hazards, providing operators with complete peace of mind during continuous operation.

6.Air Separation Process

• The system adopts cryogenic distillation technology, including air compression, purification, cooling, liquefaction, and fractional distillation. This process enables continuous oxygen production with exceptional purity stability.
