Abstract:Helium, recognized as a scarce and vital strategic resource, is predominantly extracted from natural gas through the cryogenic separation method. Nevertheless, conventional cryogenic separation processes are plagued by challenges, such as elevated energy consumption, diminished helium extraction efficiency, and escalated production costs. Through the study of various helium extraction methods and their technological characteristics, this paper proposes a novel natural gas cryogenic−membrane separation helium e… Show more
