LNG Vaporization Equipment: Core Unit for Clean Energy Conversion

LNG Vaporization Equipment: Core Unit for Clean Energy Conversion

LNG vaporization equipment serves as a critical component in the liquefied natural gas (LNG) supply chain, converting LNG at -162°C into gaseous state at ambient temperature through heat exchange for industrial, residential, or power generation applications. Its core function is to achieve phase transition safely and efficiently while enabling energy recovery and environmental compliance.

1. Multi-Technology Vaporization for Full-Scenario Adaptation

Four vaporizer types are deployed based on heat sources:

• Ambient Vaporizers: Utilize natural air convection (zero energy consumption but climate-dependent) 7;
• Submerged Combustion Vaporizers (SCV): Heat water baths via fuel combustion, ideal for large-scale continuous supply with high efficiency 8;
• Electric Heaters: Enable precise temperature control in areas lacking waste heat resources;
• Steam-Heated Units: Integrate industrial waste heat to reduce operational costs 2.

Typical application: A 70-ton/day integrated system can simultaneously achieve cold energy power generation, refrigeration, and ice storage, with comprehensive energy efficiency reaching 42.5% 9.

2. Skid-Mounted Integration for Rapid Deployment

Modern vaporization stations adopt modular designs, integrating vaporization, pressure regulation, metering, and odorization into a single skid:

• Reduce on-site installation workload by 70% and accelerate commissioning 8;
• Incorporate smart monitoring systems for real-time detection of pressure, flow, and leakage risks 5.

3. Multi-Layer Safety Protections

Addressing natural gas flammability hazards:

• Cryogenic Material Resistance: Austenitic stainless steel and aluminum alloys prevent brittle fractures at -162°C 8;
• Leak Prevention: Dual-seal valve assemblies + emergency shutdown system (response time <3 seconds) 8;
• Ventilation Redundancy: Semi-open structure with mechanical forced exhaust to prevent gas accumulation 5.

4. Cold Energy Recovery Enhances Economic Value

Innovative cold energy recycling during vaporization:

• Pre-cool power generation working fluids or drive refrigeration systems, reducing external electricity consumption 9;
• Cold energy recovery rate reaches 24% of total energy, cutting annual CO₂ emissions by 14,500 tonnes 29.

Applications and Value Proposition

Widely deployed in LNG receiving terminals, city gate stations, industrial fuel supply, and refueling stations to deliver:
✅ High-Efficiency Conversion: Gasification loss rate <0.1%;
✅ Cost Optimization: Cold energy utilization lowers operating costs by $0.0049/kWh 2;
✅ Eco-Compliance: Replaces coal/oil fuels, reducing sulfur oxide emissions by >90% 4.

Reference case: CNOOC’s coastal LNG project achieved nationwide deployment and reduced end-user gas prices via integrated vaporization solutions 8.
