I. Core Basic Parameters (General & Capacity Classification)

Core Process Parameters

• Liquefaction temperature: -162°C (atmospheric pressure)
• Liquefaction processes: MRC (Mixed Refrigerant), propane pre-cooling + MRC, nitrogen expansion, cascade refrigeration
• Feed gas pretreatment: CO₂ removal, H₂S removal, dehydration, de-heavy hydrocarbon, demercuration, compliant with GB 17820 / ISO 13686
• BOG handling: BOG compressor + recondenser, recovery rate ≥ 95%
• Storage tanks: atmospheric / low-pressure (0.2–0.8 MPa), inner tank 304L / 9%Ni steel, outer tank carbon steel with insulation
• Power consumption: approx. 0.29–0.31 kWh/Nm³ for large-scale plants; slightly higher for small skid-mounted units
• Control system: DCS + SIS, supporting remote monitoring and unattended operation

• Small skid-mounted: 100,000–500,000 Nm³/d (36,000–180,000 t/y), small footprint, modular, fast commissioning
• Medium-scale: 1,000,000–3,000,000 Nm³/d (360,000–1,080,000 t/y), suitable for regional supply / distributed energy
• Large / extra-large: 5,000,000 Nm³/d + (1.8 million t/y +), single train up to 7.8 million t/y (Qatar)
• Typical large plant: 2,000,000 Nm³/d (720,000 t/y), 2×30,000 m³ storage tanks, vaporization capacity 3,000,000 Nm³/d

Core: Energy Security + Low-Carbon Compliance

• Pain point: Dependence on Russian pipeline gas; LNG import penetration over 65% with strong demand for terminals and storage.
• Highlights:
• Ensures energy supply security, supporting the EU’s REPowerEU strategy.
• Low-sulfur, low-nitrogen, compliant with EU ETS and FuelEU Maritime.
• Matches FSRU, terminal expansion and peak-shaving storage.
• Stable supply with long-term contracts + spot trading to hedge price volatility.

• North America (USA, Canada)
• Low-cost shale gas supply; world’s largest LNG exporter (230 million t/y).
• Modular construction reduces cost by 15–20%.
• Main export markets: Europe (over 50%) and Asia-Pacific.
• Latin America (Brazil, Argentina, Chile)
• LNG used for emergency power generation during water shortage.
• Replaces diesel / heavy oil for industry and city gas.
• Small/medium LNG plants fit weak pipeline networks.

3. Southeast Asia

Core: Growth Engine + Hub + Fuel Replacement

• Accounts for over 60% of global LNG demand growth.
• India’s demand growing 8%+ annually; China imports over 120 million t/y.
• Singapore, Malaysia as regional LNG bunkering and transshipment hubs.
• Replaces coal / heavy oil in power, steel, cement, shipping.
• Massive investment in terminals, tanks and stations, ideal for small/medium LNG plants.

• World-leading natural gas reserves (Qatar, Iran, Saudi Arabia).
• Ultra-large-scale exports; single-train cost as low as ~$2/MMBtu.
• Emerging as a global LNG bunkering hub (Oman).
• Dual model: domestic power/industry + export to Europe/Asia.
• Large plants can integrate CCUS for low-carbon compliance.

5. Africa

Core: Resource Development + Local Power + Export to Europe

• Huge untapped gas resources (Nigeria, Mozambique, Tanzania).
• Fast monetization via FLNG / small onshore plants.
• Solves power shortage for industry and residential use.
• Becomes a new supply source for Europe to replace Russian gas.
• Lower investment threshold and shorter payback period.

• Energy transition bridge: cleaner than coal/oil, more stable than renewables.
• Flexible trade: seaborne worldwide, no pipeline constraints.
• Scalable: large plants for cost efficiency; small skids for remote areas.
• Eco-friendly: low emissions, compatible with CCUS and global carbon policies.
• Full-chain integration: covers upstream gas fields, midstream liquefaction, downstream regasification and distribution.
