Technical Requirement Analysis of Domestic Helium Liquefaction,Storage,and Trans-portation
In order to meet the rapid growth of domestic demand for helium,effectively ensure the safety of domestic helium use,and ensure the smooth operation of related industries,the domestic de-mands for helium liquefaction and storage technology are analyzed from the aspects of helium extraction and liquefaction technology,helium liquefaction storage technology,liquid helium transportation technology,and product application,and the end user's demands for liquid helium and helium recov-ery technology are introduced.The results show that compared with other helium extraction processes,cryogenic liquefaction helium extraction has the advantages of high efficiency,high purity,and good compatibility with downstream storage and transportation processes,making it the most widely used natural gas helium extraction technology in the world at present.Compared with high-pressure helium and gas storage facilities,liquefied helium storage has the advantages of high efficiency,high safety,high purity,and less loss.Liquid helium has obvious advantages in long-distance and high-capacity transportation.More than 40%of end users use liquid helium as a medium.To avoid the loss of helium resources,it is necessary to ensure the effective utilization of liquid helium and timely recovery and re-liquefaction of the gasification part.Therefore,helium liquefaction technology and liquid helium stor-age and transportation technology are the keys to solving the current domestic helium shortage and ef-fective utilization,and it is necessary to achieve technological breakthroughs in improving the perfor-mance of domestic key equipment and reducing costs.
