What considerations are there in the design of the ventilation system for a self-bunded fuel tank

2025-07-10 Leave a message

Ventilation System Design for Self-Bunded Fuel Tanks

1. Pressure Equalization

  • Maintains balance between internal/external pressure
  • Prevents vacuum formation during fuel withdrawal
  • Avoids over-pressurization that could damage tank structure
  • Technical Specification

    Calibrated vents activate at 0.5-2 psi thresholds for vapor release/air intake

    2. Vapor Control Systems

  • Limits VOC emissions to meet environmental regulations
  • Complies with:
    • EPA Quad O (US)
    • EU Solvent Emissions Directive
  • Activated Carbon Filters
    Catalytic Converters
    Function

    Traps or oxidizes vapors before atmospheric release

    3. Contamination Protection

  • Essential protective components:
    • Weatherproof covers
    • Flame arrestors (mesh/perforated plates)
  • Prevents ignition of flammable vapors
  • Blocks debris, rain, or snow ingress
  • Safety Mechanism

    Flame arrestors cool and extinguish sparks entering/exiting the system

    4. Airflow Configuration

  • Flow rates customized based on:
    • Tank size
    • Usage patterns
  • High-flow vents for rapid fueling/dispensing
  • Low-flow designs for static storage
  • Design Consideration

    Ventilation path must avoid contact with outer bund  effluent

    5. Compliance & Durability

  • Meets regional standards:
    • UL 142 (North America)
    • EN 12285-1 (Europe)
  • Constructed with corrosion-resistant metals
  • Tested for temperature extremes and long-term reliability
