摘　　要：氦气作为一种不可再生的战略性稀有气体,主要来自于含氦天然气中,一般采用深冷技术提纯获得。但深冷法获得的氦气成本较高。为降低氦气提取成本,在对传统深冷技术进行调研分析的同时,对变压吸附、膜分离、吸收法、水合物法等单一分离技术及多技术组合方法进行了分析对比,结果表明,多技术组合提取分离氦气可以有效打破单一分离技术的“瓶颈”,降低投资和消耗,具有更好的应用前景。As a non-renewable strategic rare gas,helium mainly comes from helium containing natural gas,which is generally purified by cryogenic technology.However,the cost of helium obtained by cryogenic method is high.In order to reduce the extraction cost of helium,the traditional cryogenic technologies such as pressure swing adsorption,membrane separation,absorption method,hydrate method and multi-technology combination methods were analyzed and compared.The results show that the multi-technology combination extraction and separation of helium can effectively break the“bottleneck”of single separation technology,reduce investment and consumption,and has a better application prospect.
