Industrial Air Separation for Oxygen & Nitrogen
An Oxygen & Nitrogen Gas Plant is an industrial facility designed to separate atmospheric air into its main components — primarily oxygen (O₂) and nitrogen (N₂) — for industrial, medical, and commercial applications.
Since air is roughly 78% nitrogen, 21% oxygen, and small amounts of other gases, these plants use specialized separation technologies to isolate and purify each gas with exceptional precision.
Tech Care India designs and manufactures these plants with end-to-end support — covering installation, commissioning, and annual maintenance to ensure peak performance from day one.
How an Air Separation Plant Works
Air Compression
Atmospheric air is drawn in and compressed using air compressors to required pressure.
Air Purification
Compressed air passes through filters removing dust, moisture, CO₂ and hydrocarbons.
Cooling Process
Purified air is cooled to very low temperatures until it fully liquefies.
Cryogenic Distillation
Liquid air is separated based on different boiling points of O₂ and N₂.
Collection & Storage
High-purity oxygen and nitrogen are collected in storage tanks or sent to cylinder filling.
Air Compression
Atmospheric air is drawn in and compressed using air compressors to the required working pressure.
Air Purification
Compressed air passes through filters and purification units to remove dust, moisture, CO₂ and hydrocarbons.
Cooling Process
Purified air is cooled to very low temperatures until it fully liquefies for separation.
Cryogenic Distillation
Liquid air is separated based on different boiling points — nitrogen at -196°C and oxygen at -183°C.
Collection & Storage
High-purity oxygen and nitrogen are collected in storage tanks or sent for cylinder filling.
Separation by Boiling Point
Liquid air is separated using the principle that different gases have different boiling points. Because nitrogen has a lower boiling point than oxygen, it vaporizes first and rises while oxygen remains as liquid — achieving ultra-high purity separation.
Output Options & Storage Methods
After separation, high-purity oxygen and nitrogen can be delivered in multiple formats depending on your operational requirements.
Cylinder Filling
Gaseous oxygen or nitrogen is compressed into high-pressure cylinders for portable industrial, medical, or laboratory use.
Liquid Storage (LOX / LIN)
Gases stored as liquid oxygen (LOX) or liquid nitrogen (LIN) in cryogenic tanks for bulk, long-term supply needs.
Pipeline Supply
Continuous on-site pipeline distribution of gaseous oxygen or nitrogen directly to production lines and processes.
Key Components of an Oxygen & Nitrogen Plant
A complete plant integrates multiple precision-engineered systems working in sequence to deliver reliable gas output.
Choosing the Right Generation System
Different production scales and purity requirements call for different separation technologies. We offer all three major systems.
Cryogenic Air Separation Plant
The industry standard for large-scale production. Delivers ultra-high purity oxygen and nitrogen (99%+) through liquefaction and fractional distillation. Ideal for hospitals, industrial gas suppliers, and heavy manufacturing.
PSA Plant (Pressure Swing Adsorption)
Uses adsorption materials to selectively separate gases. Best for smaller oxygen generation systems where moderate purity is sufficient. Compact, cost-effective, and easy to operate.
Membrane Separation Plant
Uses hollow-fibre membranes to separate nitrogen from air. Suitable for lower purity nitrogen generation with no moving parts, zero maintenance, and instant start-up — perfect for purging and blanketing applications.

What Makes Our Oxygen Plants Stand Out
Medium Operating Pressure
Operates at just 32–35 kg/cm², significantly reducing energy consumption vs conventional high-pressure systems.
Cryogenic Liquid Oxygen Pump
Seamless cylinder filling of dry gaseous oxygen at desired pressure up to 200 kg/cm²g — safe and efficient.
Integrated Molecular Sieve Dryer
Removes moisture, CO₂, acetylene, hydrocarbons, and all impurities before separation for ultra-clean output.
Fast Start-Up
Only ~8 hours to resume full production after defrost cycle. Short stop requires just 1–1.5 hours to restart.
Dual Production Capability
Simultaneously produces high-purity Oxygen (99.6%) and Nitrogen (99.9999%) at no additional cost.
Compact Layout
Complete plant and cylinder filling station fits within a compact footprint — ideal for space-constrained sites.
Built to Outperform Industry Benchmarks
Industry-Leading Energy Efficiency
For 250 m³/hr capacity and above under normal continuous operation — one of the lowest energy profiles in the industry.
Exceeds Rated Output
Output typically exceeds rated capacity due to efficient design, precision engineering, and high-quality materials.
Long Defrosting Cycle
Super-efficient expansion engine ensures rapid cooling, reduced startup time, and long-term power savings.
How Cryogenic Air Separation Works
Air Compression
Atmospheric air drawn in and compressed to required working pressure.
Purification
Molecular sieves remove CO₂, moisture, acetylene & hydrocarbons.
Heat Exchange
Compressed air pre-cooled through multi-pass heat exchangers.
Liquefaction
Expansion engine generates refrigeration, liquefying the air stream.
Separation
Distillation columns separate O₂ & N₂ for delivery or cylinder filling.
