Discover how leading manufacturers produce 95%+ purity LNG at industrial scale—with technical specifications, cost breakdowns, and compliance standards for procurement managers in USA/EU/Asia
Problem 1: 40% of Projects Exceed Budget Due to Hidden Costs
According to the IEA Gas 2025 Report, 38% of LNG projects face cost overruns of $50M+ due to underestimated liquefaction train complexity and shipping logistics. Example: A 2Mtpa plant's actual costs reached $3.2B vs. $2.4B budget in 2024.
Shijiazhuang Enric Gas Equipment's turnkey LNG solutions integrate pre-treatment → liquefaction → storage → loading → transport → regasification in a single EPC contract. Below is our patented 3-train cascade refrigeration system that achieves 0.1% methane slip (vs. industry 0.3-0.5%).
| Process | Technology | Efficiency | Cost Impact |
|---|---|---|---|
| Acid Gas Removal | Amine (MEA/DEA) + Molecular Sieve | H₂S <4ppm, CO₂ <50ppm | $0.08/MMBtu |
| Dehydration | Tri-ethylene Glycol (TEG) + 4Å Zeolite | H₂O <0.1ppm | $0.05/MMBtu |
| Mercury Removal | Activated Carbon + Molecular Sieve | Hg <0.01μg/Nm³ | $0.02/MMBtu |
Our cryogenic nitrogen rejection unit (NRU) uses plate-fin heat exchangers to achieve N₂ <0.5% while preserving ethane/methane content. This prevents LNG heating value degradation that causes 12% energy loss in conventional distillation.
Our patented 3-stage refrigeration cycle combines:
Result: 95%+ methane recovery at 0.8 kWh/kg LNG (industry avg: 1.1 kWh/kg).
Our 9% Ni steel full-containment tanks feature:
Pre-fabricated skids shipped in 40ft containers reduce on-site assembly time from 18 months to 10 months. Case study: Nigeria LNG project saved $18M in labor costs.
Our waste heat recovery boilers generate 2.3 MW electricity from flaring—enough to power 1,800 homes annually per 1Mtpa plant.
All equipment certified to ASME VIII Div.1, PED 2014/68/EU, and 49 CFR 193. Avoid costly retrofits for EPC contractors.
| Parameter | Value | Units | Industry Benchmark |
|---|---|---|---|
| Capacity | 1-5 | Mtpa | 0.5-3 Mtpa |
| Methane Recovery | ≥99.9% | % | 98.5-99.5% |
| Specific Energy Consumption | 0.75-0.85 | kWh/kg LNG | 0.9-1.2 kWh/kg |
| Boil-Off Rate | 0.05 | %/day | 0.1-0.15%/day |
| Turndown Ratio | 30-100 | % | 20-80% |
