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.
Abstract
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 re-sources 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 adsorp-tion)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 cryo-genic method and membrane separation,light hydrocarbon recovery and denitrification,hydrate and cata-lytic dehydrogenation,which improving the recovery and purity of helium and reduced the cost,thus have broad prosperity of application.
