Air & Gas Separation Units (ASU)
Air and gas separation systems are essential for producing industrial gases such as oxygen, nitrogen, argon, hydrogen, and CO₂ across the oil & gas, petrochemical, power generation, medical, and renewable energy sectors. We offer a full range of Cryogenic ASU, PSA/VPSA Oxygen & Nitrogen Generators, Hydrogen PSA Purifiers, Membrane Systems, and Containerized Mobile Units, designed for maximum efficiency, flexibility, and long-term reliability.
Cryogenic Air Separation Units (ASU)
Cryogenic separation is the leading technology for large-scale industrial gas production. Incoming air is compressed, purified, deeply cooled to cryogenic temperatures, liquefied, and then distilled into its components.
Products (Liquid & Gaseous)
Cryogenic ASUs produce high-purity liquid and gaseous industrial gases:
- LIN – Liquid Nitrogen
- LOX – Liquid Oxygen
- LAR – Liquid Argon
Additional Extracted Gases
Depending on the configuration, rare gases can also be produced:
- Neon (Ne)
- Krypton (Kr)
- Xenon (Xe)
Typical Purity Levels
- Oxygen: 99.5%+
- Nitrogen: up to 99.999%
- Argon: up to 99.999%
Applications
- Refining & petrochemicals
- Steel & metallurgical industries
- LNG plants (LIN for cooling cycles)
- Industrial gas distribution networks
- Medical oxygen production and storage
Cryogenic ASU is the best solution for high-capacity and ultra-high-purity gas production.
Pressure Swing Adsorption (PSA / VPSA)
PSA systems generate oxygen or nitrogen by using adsorbent materials that selectively trap impurities under pressure. The process cycles between adsorption and desorption to maintain constant output.
PSA / VPSA for Oxygen & Nitrogen Production
Purity Levels:
- Oxygen: 90%–95%
- Nitrogen: 95%–99.999%
Used In:
- Oil & gas facilities
- Chemical plants
- Food & beverage industry
- Electronics manufacturing
- Industrial packaging and inerting
- Medical oxygen supply in hospitals and clinics (PSA O₂ is widely used globally)
PSA units are known for low energy consumption, fast startup, modular design, and reliable 24/7 operation.
PSA for Hydrogen Purification & CO₂ Capture
In hydrogen production plants, PSA units are used to purify hydrogen up to 99.999%, removing CO₂, CO, CH₄, and nitrogen from the gas stream.
Used In:
- Hydrogen production via steam methane reforming
- Biomass and waste gasification
- Renewable hydrogen from electrolysis
- Syngas polishing operations
- Industrial CO₂ capturing and purification
PSA is the global benchmark for hydrogen purification due to its efficiency, modularity, and high purity output.
Containerized / Mobile PSA Packages (Skid + Container)
A widely adopted industrial practice is to design PSA systems in containerized mobile configurations. These packages include:
- Air compressor
- Dryer system
- Filters
- Storage tanks
- PSA adsorption towers
- Control and monitoring system
Key Applications:
- Oil drilling rigs
- Pipeline construction projects
- Well testing operations
- Remote gas fields
- Temporary nitrogen supply for shutdowns and maintenance
Benefits of Containerized PSA Units:
- Fully mobile — can be transported by truck or trailer
- Rapid deployment with plug-and-play installation
- Weather-protected and secure
- Reduced on-site construction work
- Ideal for remote and temporary industrial sites
All installed inside a standard ISO container (20ft or 40ft).
We engineer and supply complete containerized PSA systems, fully assembled, tested, and ready for field operation. These units are particularly valuable where mobility and fast relocation are operational requirements.
Membrane Separation Systems
Membrane systems use selective permeation to separate gases based on molecular size and solubility. They are compact, modular, and excellent for on-site nitrogen generation or hydrogen separation.
Membranes for Nitrogen and Oxygen
- Nitrogen purity: 95%–99.5%
- Oxygen-enriched air up to 40% O₂
Commonly used in offshore platforms, chemical plants, and inerting systems.
Membrane Systems in Hydrogen Production (Seawater + Solar Energy)
Membrane technologies are increasingly integrated into renewable hydrogen production, especially in systems involving:
Process Steps:
- Seawater intake & pretreatment
- Desalination or membrane purification
- Electrolysis powered by solar or hybrid renewable energy
- Production of hydrogen and oxygen
- Final polishing via membrane or PSA purification systems
Green Hydrogen from Seawater - This approach delivers clean hydrogen and oxygen, supporting global transitions toward green fuel, energy storage, and decarbonization. Many countries are investing heavily in this value chain due to its long-term sustainability, scalability, and compatibility with net-zero energy goals.
