Highlights:
1、LifenGas has secured a major BOG helium recovery project with advanced integrated technology.
2、The system achieves over 95% helium recovery with 99.9999% purity.
3、Innovative cryogenic processes enable efficient extraction from LNG by-product gas.
LifenGas has recently been awarded the BOG (boil-off gas) helium recovery and liquefaction project from JinHong Gas Co., Ltd. (Stock Code: 688106). The project will deliver a complete system designed to extract and liquefy enriched helium in non-condensable gas streams generated during natural gas liquefaction.
Headquartered in Suzhou, JinHong Gas is a comprehensive supplier specializing in R&D, production, sales, and technical services of gases. The company provides one-stop gas solutions covering bulk gases, specialty gases, and related services. Its partnership with LifenGas marks an important step in expanding its presence across the rare gas industry chain.
The project presents a short timeline, high standards, and advanced technology. Upholding its commitment to precision and quality, LifenGas has already completed detailed planning and full mobilization. A dedicated core engineering team is actively advancing preliminary design, equipment manufacturing, and construction preparation to ensure efficient execution and on-schedule delivery.
Helium is a scarce strategic resource essential for aerospace, semiconductor manufacturing, and MRI systems. However, China is naturally poor in Helium. Helium concentrations in its natural gas are typically below 0.05%, far lower than levels of up to 7.5% found in some gas fields in the United States. Direct extraction from conventional natural gas is therefore often uneconomical.
The BOG recovery route offers a smarter alternative. During LNG liquefaction, helium cannot condense due to its extremely low boiling point and becomes concentrated in BOG streams. This creates a viable source for recovery. To unlock this potential, LifenGas technical team developed a hybrid process combining deep cryogenic separation, low-temperature adsorption, and ultra-low-temperature expansion. The system operates across an extreme temperature span from 20°C down to –269°C, pushing domestically produced helium recovery and liquefaction equipment to a new technical level.
The helium recovery unit boasts several key advantages:
High Extraction Rate: Helium extraction exceeds 95%, enabling efficient capture of helium resources from BOG streams.
Ultra-high Purity: Product helium reaches 99.9999% purity, with proprietary technology reducing neon content to below 1 ppm.
Low Energy Consumption: Optimized process integration significantly cuts operating power demand and improves project economics.
Advanced Automation: A modern control system enables intelligent operation, stable performance, and user-friendly management.
Winning this contract highlights LifenGas’s strong technical expertise and execution capability in rare gas recovery and liquefaction. It also marks another milestone for the company in high-end equipment for the energy and chemical industries. LifenGas will continue to drive innovation, focus on client needs, and deliver high-quality projects on schedule while supporting the efficient use and supply security of strategic gas resources.
