Short answer: Industrial gases are typically produced through air separation or chemical processes, stored under pressure or as cryogenic liquids, and delivered via cylinders, bulk tanks, or on-site systems depending on usage needs.
Industrial gases — such as nitrogen, oxygen, argon, carbon dioxide, and hydrogen — are essential across manufacturing, healthcare, food processing, and technology. Understanding how they are produced, stored, and delivered helps businesses make informed decisions about supply and efficiency.
How Industrial Gases Are Produced
Most industrial gases originate from air separation. Ambient air is compressed, cooled, and separated into its primary components:
- Nitrogen (≈78%)
- Oxygen (≈21%)
- Argon (trace amounts)
This process is typically done using cryogenic distillation, where air is cooled to extremely low temperatures and separated based on each gas’s boiling point.
Other gases are produced through chemical processes:
- Carbon dioxide (CO₂): captured as a byproduct of fermentation or industrial production
- Hydrogen: produced through steam methane reforming or electrolysis
How Industrial Gases Are Stored
Storage depends on the gas type and volume requirements:
Compressed Gas Cylinders
Gases are stored at high pressure in steel or aluminum cylinders. This method is ideal for smaller-scale or intermittent use.
Cryogenic Liquid Storage
Gases like nitrogen, oxygen, and CO₂ can be cooled into liquid form and stored in insulated tanks. This allows large volumes to be stored efficiently in a smaller footprint.
On-Site Generation
Some facilities generate gases like nitrogen or oxygen on-site using specialized equipment, reducing the need for delivery.
How Industrial Gases Are Delivered
Delivery methods are tailored to usage levels and operational needs:
- Cylinder delivery: Regular exchange of individual tanks
- Bulk delivery: Scheduled refills of large on-site storage tanks
- On-site systems: Continuous supply with minimal external delivery
Advanced systems may include remote monitoring and telemetry, allowing suppliers to track usage and schedule deliveries proactively.
The Bottom Line
Industrial gases move through a carefully controlled lifecycle — from production to storage to delivery — designed to ensure purity, safety, and reliability at every stage.
Partnering with an experienced supplier like Irish Industrial Gases ensures your operation receives the right gas, in the right form, at the right time.
