Fuel Compatibility Guide for Self-Bunded Tanks
Standard Fuels
- Gasoline/Diesel/Kerosene: Steel or HDPE tanks
- Anti-corrosive coatings for steel
- HDPE's chemical inertness ideal for hydrocarbons
- Example: HDPE for diesel in fleet operations
Note: Diesel's low volatility pairs well with HDPE's resistance properties.
Biofuels
- Ethanol blends: HDPE or FRP preferred
- Ethanol's hygroscopic nature risks steel corrosion
- Special linings required in some regions
Warning: Moisture accumulation in ethanol blends can degrade unlined steel tanks.
Gaseous Fuels
- LPG/CNG: Require pressure-rated tanks
- Must comply with ASME standards
- Additional safety features needed
Specialized Fuel Considerations
Aviation Fuels
- Jet A/A1: High-purity steel tanks
- Food-grade coatings required
- Must meet ASTM D912 cleanliness standards
Alternative Fuels
- Hydrogen: Composite-lined tanks only
- Methanol: FRP or stainless steel required
- High corrosion potential
Flammable Solvents
- Acetone/Toluene: Steel with epoxy linings
- Plastic degradation risk over time
- Verify compatibility via MSDS
Regulatory & Operational Requirements
- Standards: EPA (U.S.), PPG2 (UK), ISO 13628 (marine)
- Vapor control: Required for high-volatility fuels like gasoline
- Temperature management: Critical for fuel stability
- Material verification: Always check against MSDS data
Key Selection Criteria
- Material compatibility with specific fuel type
- Compliance with industry and regional regulations
- Temperature and vapor pressure requirements
- Long-term degradation risks
- Cleanliness standards for sensitive fuels
Best Practice: Consult with tank manufacturers and fuel suppliers for specific compatibility verification.
