In today’s dynamic industrial ecosystem, oxygen is no longer just a medical or welding gas—it plays a pivotal role in sectors like steel manufacturing, pharmaceuticals, water treatment, glass production, and food processing. As demand for high-purity oxygen increases, industries are investing in on-site oxygen generation plants.
If you’re considering setting up one or simply looking to understand how they work, this blog explains in detail: What are the Components of an Industrial Oxygen Plant? We’ll break down the core subsystems, their functions, and how together they deliver reliable oxygen output.
Let’s explore the inner framework of a PSA-based industrial oxygen generation system.
Introduction to Industrial Oxygen Generation
Industrial oxygen plants are engineered to produce continuous, high-purity oxygen (up to 93%-95%) by separating it from atmospheric air using Pressure Swing Adsorption (PSA) technology or cryogenic methods.
Among the many technologies available, PSA oxygen plants are favored for their low operational costs, modularity, faster installation, and low maintenance requirements.
Understanding What are the Components of an Industrial Oxygen Plant? is crucial not only for buyers and operators but also for technicians, engineers, and consultants in the industrial gas sector.
Core Components of a PSA Industrial Oxygen Plant
Let’s break down the primary and auxiliary components that work together to ensure efficient and reliable oxygen production.
1. Air Compressor
The air compressor is the first and most critical component. It draws in ambient air and compresses it to the desired pressure level—usually around 7–10 bar—for further processing.
Key Functions:
- Supplies air for separation
- Maintains continuous flow and pressure
- Ensures the required air volume for steady oxygen production
Oil-free screw compressors are often used to maintain purity and reduce contamination risks. Alkeynes Global Projects ensures that compressors used are energy-efficient and robust for 24/7 operation.
2. Air Pre-Filtration System
Before compressed air enters the PSA unit, it must be free from dust, oil, and water. This is achieved through a multi-stage filtration system, which includes:
- Dust filters
- Coalescing filters
- Activated carbon filters
These ensure the removal of oil aerosols and other impurities that could damage downstream components or compromise gas purity.
3. Compressed Air Dryer
Moisture is a major contaminant in compressed air. The air dryer is critical to remove this moisture content.
Types used:
- Heatless desiccant dryers
- Refrigerated air dryers
Dry air ensures maximum adsorption efficiency in the next stage. The quality and performance of the dryer directly impact the life of the PSA molecular sieves.
4. Buffer Vessel (Air Receiver)
This is a pressurized storage tank that acts as a buffer between the compressor and the PSA module.
Roles:
- Stabilizes air pressure and flow rate
- Provides reserve air during high-demand periods
- Reduces compressor load by minimizing frequent on/off cycles
Typically made of stainless or carbon steel, these tanks are pressure-tested and certified for industrial use.
5. PSA Module with Adsorption Towers
The heart of the system, the PSA (Pressure Swing Adsorption) unit consists of two or more towers filled with Zeolite Molecular Sieves (ZMS).
How It Works:
- Compressed air enters one tower where nitrogen is adsorbed
- Oxygen passes through as product gas
- Once the first tower saturates, the system switches to the second
- Meanwhile, the first tower regenerates by depressurization
This cyclic operation continues to produce a consistent stream of high-purity oxygen.

6. Oxygen Buffer Tank
After oxygen is produced, it is stored in a buffer tank to balance variations in demand and ensure constant delivery pressure.
Key Features:
- Prevents pulsations in oxygen supply
- Allows steady downstream flow to processes
- Acts as a temporary reservoir during power or compressor failure
The size and material of this tank depend on the plant’s capacity and usage pattern.
7. Oxygen Flow Meter & Analyzer
To maintain quality assurance and traceability, each plant is equipped with:
- Digital oxygen purity analyzers
- Flow meters to measure output (Nm³/hr)
- Pressure gauges for monitoring tank levels
This instrumentation ensures that oxygen meets the required purity level, generally >93% for industrial applications.
8. Control Panel with Automation (PLC/SCADA)
Modern PSA oxygen plants feature smart controls to monitor, regulate, and manage operations.
Features:
- Auto-start and auto-stop
- Alarm systems for low purity or pressure
- Data logging for compliance and auditing
- Remote monitoring and diagnostics
Alkeynes provides PLC or SCADA-based control panels with intuitive user interfaces and built-in safety protocols.
9. Oxygen Distribution System
After generation, oxygen is supplied to various application points via a manifold and piping system, designed for:
- Minimal pressure drops
- Leak-proof connections
- Stainless steel piping (where purity is critical)
Industries may connect the system to furnaces, packaging lines, cutting torches, or fill it into oxygen cylinders.
10. Safety & Auxiliary Systems
Safety is integral to the design of an oxygen plant. Standard systems include:
- Pressure relief valves
- Emergency shut-down buttons
- Oxygen non-return valves
- Flame arrestors (if required)
- Ventilation and exhaust systems
Additionally, backup power generators, silencers, and air intake filters form part of auxiliary infrastructure.
Optional Add-Ons for Customization
Depending on your industry needs, the plant can be equipped with:
- Cylinder filling stations (with boosters)
- Oxygen purity upgrade systems (up to 99%)
- Medical-grade sanitization filters
- Skid-mounted portable systems
- Online cloud monitoring dashboards
Alkeynes Global Projects specializes in tailor-made oxygen generation systems based on client-specific technical and environmental requirements.
