| 摘 要： | 膜分离法与深冷法联合用于从天然气中提氦，是一种新的从贫氦天然气分离氦的工艺流程。该工艺利用膜分离法从贫氦天然气制取富氦天然气，经深冷分离及精制而获得纯氦。该方法使得在同样氦气产出的情况下，深冷分离的规模减小，在同样深冷分离规模下氦气产量增加。文章给同了膜分离单元工艺流程，举例测算了膜分离单元的工艺数据，以及膜分离法与深冷法联合用于从天然气中提氦的工艺流程的特点。

| Abstract: | A novel permeation-cryogenic hybrid scheme is proposed for helium separation from natural gss.The key concept of the suggested scheme is to separate helium-enriched gas stream from natural gas and then recover helium by conventional partial condesation and purification steps, thereby, minimizing energy intensive and expensive compression. gas liquefaction and vaporization. A conceptual flow scheme for the proposed hybrid process is outlined. |
