Helium recovery from liquefied natural gas waste stream using nanoporous mxene materials

许多液化天然气（LNG）行业的废水中仍然含有宝贵的氦气，这可能是维持我们经济增长的下一种矿物。该项目旨在通过分层二维材料有效地将氦从甲烷和氮中分离出来。该项目将试图了解这些纳米级Mxene薄片的组装行为及其分子筛分性能。澳大利亚在全球液化天然气（LNG）生产和贸易中发挥着主导作用。该项目预计将进一步使澳大利亚在天然气加工和材料开发领域处于领先地位。这将带来显著的好处，例如通过先进的多孔纳米材料经济有效地生产有价值的副产品氦，进一步提高这些液化天然气项目的经济性。

The waste streams from many liquefied natural gas (LNG) industries still contains valuable helium, a possible next mineral to sustain our economic growth. This project aims to efficiently separate helium from methane and nitrogen via the layered two dimensional materials. This project will seek to understand the assembling behaviour of these nano-sized Mxene flakes and their molecular sieving properties. Australia is playing a leading role in the global liquefied natural gas (LNG) production and trade. This project expects to further position Australia at the forefront of intellectual leadership in the field of gas processing and material development. This will have significant benefits, such as further improving these LNG projects economics by cost-effectively producing helium as a valuable by-product via advanced porous nano-materials.
