摘　　要：氦是一种广泛应用于国防与高科技工业的战略资源。含氦天然气是工业化提氦的主要来源。我国已探明的天然气中含氦气的天然气资源少,含氦天然气资源中氦含量也较低,氦资源极其宝贵且提取困难,介绍并总结了国内外提氦技术。变压吸附法与膜分离法工艺简单,产品氦的纯度高;深冷工艺虽然能耗高,但技术成熟,氦回收率高,是目前应用最广泛的技术。集成提氦技术综合多种分离工艺,如深冷与膜分离、轻烃回收与脱氮、水合物与催化脱氢集成技术,提高了氦回收率与纯度、降低提氦成本,具有广阔的应用前景。Helium is a strategic resource widely used in defense and high-tech industries.The main source of industrialization in helium extraction is helium-type natural gas.There are few natural gas resources containing helium in China’s proven natural gas,and a small amount of natural gas resources containing helium also have low helium content.Helium resources are extremely precious and difficult to extract.The technology at home and abroad is introduced and summarized:PSA(pressure swing adsorption)method and membrane separation method own the simple flow and high purity of helium product;cryogenic method,although it suffers from high consumption in energy,is a mature technology with high recovery of helium and is currently the widely used technology.Integrated helium-extraction technologies are a combination of multiple technologies for separation,such as helium extraction integrated with cryogenic method and membrane separation,light hydrocarbon recovery and denitrification,hydrate and catalytic dehydrogenation,which improving the recovery and purity of helium and reduced the cost,thus have broad prosperity of application.
