Product Overview
The Chemical Plant Oxygen Supply System is a fully engineered on-site oxygen generation solution designed for continuous, large-scale industrial applications in the chemical and petrochemical industries.
Unlike traditional liquid oxygen (LOX) delivery or cylinder-based supply, our system enables independent oxygen production directly at the plant site, ensuring stable, safe, and cost-efficient oxygen availability for critical chemical processes.
The system integrates air compression, purification, oxygen separation (PSA/VPSA), storage, and intelligent control into a complete turnkey engineering solution.
It is widely used in:
- Chemical oxidation processes
- Petrochemical refining
- Nitric acid & hydrogen peroxide production
- Wastewater treatment systems
- Catalyst regeneration systems
- Industrial oxygen-enriched processes
Why On-site Oxygen Generation for Chemical Plants?
Chemical industries require continuous, stable, and high-purity oxygen supply. Traditional supply methods face major limitations:
Liquid Oxygen (LOX) Challenges
- High logistics and transportation cost
- Supply chain dependency risk
- Safety hazards during storage and handling
- Price fluctuation in global gas markets
Cylinder Supply Limitations
- Not suitable for continuous production
- Frequent replacement required
- High labor and storage cost
Our Solution Advantage
Our PSA/VPSA oxygen generation system eliminates these issues by providing:
- Continuous 24/7 oxygen production
- Stable supply independent from external vendors
- Significant reduction in oxygen cost (OPEX savings up to 30–60%)
- On-demand production aligned with plant consumption
System Working Principle
Our system is based on proven Pressure Swing Adsorption (PSA) or Vacuum Pressure Swing Adsorption (VPSA) technology.
Working Process:
Step 1: Air Compression
Ambient air is compressed to required pressure using an energy-efficient air compressor.
Step 2: Air Purification
Advanced filtration removes:
- Oil
- Moisture
- Dust particles
Step 3: Oxygen Separation
Air flows into adsorption towers filled with zeolite molecular sieve, where:
- Nitrogen is absorbed
- Oxygen is separated and collected
Step 4: Oxygen Buffering
Oxygen is stabilized in buffer tanks to ensure:
- Constant pressure
- Stable flow output
Step 5: Final Delivery
Oxygen is delivered directly into chemical process pipelines or storage systems.
