Helium is an important strategic resource.China belongs to a helium poor country with a 95%import depend-ence.The vast majority of natural gas produced domestically has a helium content below0.1%.Although it does not meet the helium rich standard,when natural gas is liquefied,trace amounts of helium will be concentrated in the BOG tail gas during the liquefaction process,becoming a potential helium resource in China.This article briefly analyzed the technical characteristics of helium extraction from BOG tail gas of LNG plants,calculated the potential amount of helium resources in BOG tail gas of LNG plants in China,established an economic calculation method for BOG tail gas helium extraction pro-jects,and quantitatively analyzed the influencing factors of economic benefits.Finally,suggestions for the development of helium extraction from BOG tail gas of LNG plants in China are provided.
