中国天然气提氦产业链技术发展现状及展望

Current status and prospects of technological development of helium extraction from natural gas industrial chain in China

天然气提氦产业链的健康有序发展十分重要,关系到氦气资源供应安全。中国需要加快形成具有强劲支撑力的氦产业链,切实保障我国氦供应。从粗氦提取、粗氦精制、氦气液化、氦的储运等方面分析研究了天然气提氦产业链技术的发展现状。研究发现中国在粗氦提取、粗氦精制和气氦储运方面整体技术指标已达到国际先进水平,在氦气液化和液氦储运的装备大型化方面与国际先进水平还存在差距。为建立起技术成熟可靠和完整装备的天然气提氦产业链,需要加快氦分离膜、大型氦液化器、大型液氦罐箱研发和应用,同时加强氦领域相关标准规范体系建设,推动氦保护法的建立。

The sustainable and well-regulated development of the natural gas helium extraction industrial chain is crucial,as it relates to the security of helium resource supply.China needs to accelerate the development of a robust helium industrial chain to ensure a stable supply of helium for the country.The development status of natural gas helium extraction industrial chain,including crude helium extraction,crude helium purification,helium liquefaction,and helium storage and transportation has been analyzed and studied.The study concluded that China has achieved advanced international standard in terms of the overall technical benchmarks for crude helium extraction,crude helium purification and gas helium storage and transportation.However,there remains a gap when compared to the advanced international standard in the large-scale equipment used for helium liquefaction and the storage and transportation of liquid helium.To develop a technically mature,robust and fully equipped natural gas helium extraction industrial chain,it is imperative to expedite the development and application of helium separation membranes,large-scale helium liquefiers,and large liquid helium tanks.Additionally,strengthening the development of related code and standards and regulatory frameworks within the helium industry is essential,along with advocating for the laws to protect helium resources.
