粗氦精制技术应用及展望
Application and prospects of crude helium purification technology
摘要
Abstract
Crude helium contains small quantities of hydrocarbons,nitrogen,hydrogen and trace amounts of neon and other impurities.In order to produce certified helium products such as pure helium and high purity helium,it is essential to purify crude helium.In recent years,with the rapid advancement of technology and equipment in China's helium industry,crude helium purification technology has rapidly progressed,achieving large-scale industrial application.This paper introduces the application scenarios of crude helium purification technology,reviews the principles,indicators and typical process flow of catalytic dehydrogenation,Pressure Swing Adsorption(PSA)and low temperature adsorption in crude helium purification.It provides a detailed analysis of the technical paths,process flow arrangement and product indicators of typical industrial application for crude helium purification and concludes with a perspective on the future direction of technological development in crude helium purification.关键词
