1. LNG Regasification
Converting Liquefied Natural Gas Back to Usable Energy
Energy Sector Overview • Industrial Process Guide

2. What is LNG Regasification?
LNG regasification is the process of converting liquefied natural gas back into its gaseous form for
practical applications.
• Storage Temperature: Around -162°C (-260°F)
• Essential for heating, electricity generation, and vehicle fuel
• Enables distribution to end-users via infrastructure networks
• Critical for global energy security and sustainability

3. Why LNG Matters in Global Energy
• Cleaner alternative to coal and traditional fossil fuels
• Enables energy diversification for importing countries
• Supports transition to sustainable energy sources
• Provides economic advantages through competitive pricing

4. The LNG Regasification Process
Six critical stages in the conversion process:
• Storage & Transportation
• Unloading at Terminal
• Heating & Vaporization
• Pressure Regulation
• Distribution Networks
• End-User Delivery

5. Stage 1: Storage & Transportation
• LNG transported in specialized cryogenic tanks
• Maintains ultra-low temperatures during transit
• Prevents evaporation and energy loss
• Engineered for safety and efficiency during long-distance transport

6. Stage 2: Unloading at Terminal
Upon arrival at regasification terminal:
• LNG carriers unload cargo into insulated storage tanks
• Critical to maintain low-temperature conditions
• Prevents premature vaporization
• Ensures product quality and safety compliance

7. Stage 3: Heating & Vaporization Methods
Three primary heating technologies:
• Open Rack Vaporizers (ORV): Use seawater or ambient air
• Submerged Combustion Vaporizers (SCV): Flame submerged in water
• Heat Exchangers: Transfer heat from hot medium like seawater

8. Heating Technology Comparison
ORV
Uses seawater or ambient air as heat source
SCV
Submerged flame provides controlled heating
Heat Exchangers
Efficient heat transfer mechanism

9. Stage 4: Pressure Regulation
After heating, gaseous natural gas must be regulated:
• Ensures compliance with pipeline distribution standards
• Maintains safe operating pressures throughout network
• Prevents equipment damage and safety hazards
• Optimizes flow for efficient end-user delivery

10. Stages 5 & 6: Distribution & Delivery
Multiple distribution channels to reach consumers:
• Primary: Pipeline networks for widespread coverage
• Alternative: Truck transport for localized delivery
• Secondary: Smaller ships for regional distribution
• End-uses: Vehicle fuel, industrial heating, electricity generation
