Selecting the right cryogenic storage tank for your specific application is crucial. The stored media in cryogenic tanks can plummet to extremely low temperatures, and choosing the wrong vessel may lead to product waste or even hazardous situations. This guide will help you easily select the appropriate storage for Liquid Oxygen, Liquid Nitrogen, Liquid Argon, Liquid Carbon Dioxide, and Liquefied Natural Gas.
1.Ensure Media Compatibility
Storage media must not be interchanged arbitrarily; each medium has specific performance requirements for the tank.
Liquid Oxygen (LOX): Requires strict oxygen cleaning (per ASTM G93) to remove hydrocarbons. Any oil residue can trigger an explosion. An oxygen cleaning certificate is mandatory.
Liquid Nitrogen (LIN) & Argon (LAr): Standard inert gas tanks. The focus is on low evaporation rates and suitable pressure ratings for your application (e.g., higher pressure for welding argon).
Liquid Carbon Dioxide (LCO₂): The key difference is that it operates under high pressure. Standard LOX/LIN tanks cannot be used for carbon dioxide.
Liquefied Natural Gas (LNG): Requires special materials like 9% nickel steel to prevent brittleness at -162°C. Designs range from full containment to membrane types.
2.Tank Size & Configuration
Micro-capacity (450L – 3000L): Ideal for clinics, laboratories, and small workshops. A replacement for bulky gas cylinders.
Large-capacity (5m³ – 200m³+): Designed for high-volume industrial users. Available for customized on-site installation.
Orientation: Choose vertical to save ground space, or horizontal to fit height-restricted sites.
3.Insulation & Efficiency
Heat ingress causes evaporation loss, wasting money.
Vacuum Perlite: Cost-effective for most large tanks.
Multi-Layer Insulation (VML): Superior performance (heat leak <0.2% per day). Recommended for high-value gases like LNG or long-term storage.
ROI Tip: Compared to non-insulated tanks of equal cost, insulated tanks save over $15,000 in gas loss over 10 years.
4.Compliance & Safety
Never compromise on certification. Verify based on your region:
USA/Canada: ASME U/UM Stamp, NBIC.
Europe: CE Mark, PED.
Global: ISO 9001 with Third-Party Inspection (SGS/TUV).
5.Key Safety Features
Dual Safety Valves + Rupture Disc.
Vacuum Monitoring Port to detect insulation failure.
Leak Detection Sensors (for LNG/LOX).
Seismic Rating for earthquake-prone zones.
6.Choosing the Right Tank
Confirm gas compatibility (especially for CO₂ and LOX).
Calculate total cost (price + gas evaporation loss).
Check certifications (ASME/CE).
Prioritize insulation quality.
