摘要
氦气作为一种重要的战略资源,主要来源于富氦天然气,其在全球分布并不均匀,相较美国、卡塔尔、阿尔及利亚、俄罗斯及加拿大而言,我国天然气中含氦量较低,氦气资源较为匮乏,自产量远远小于消费量,约有95%需从国外进口。目前,常用的提氦方法有深冷法、变压吸附法、膜分离法及多技术组合法,其中多技术组合法较为适合我国的国情。
As an important strategic resource,helium gas mainly comes from helium-rich natural gas,and its global distribution is not uniform.Compared to the United States,Qatar,Algeria,Russia and Canada,the helium gas in China contains low helium and helium resources are relatively scarce,and its self-production is far lower than its consumption,about 95%of which needs to be imported from abroad.At present,deep cooling method,pressure change adsorption method,membrane separation method and multi-technology group are the commonly used helium extraction methods,among which the multi-technology group is more suitable for China's national conditions.
