摘　　要：对近年来常见的深冷、膜+深冷、膜分离3种含氦天然气提浓工艺进行了模拟,希望找到更为经济的氦气提浓方式,从而为国内低品位含氦气田的经济利用提供有益的参考。模拟发现,对于氦气体积分数为0.0416%的天然气,膜分离技术可以大幅降低氦气提浓过程的能耗,3种提浓工艺中,膜分离工艺单耗最低、氦气收率最高。因此,目前对于低品位含氦天然气提浓过程,膜分离工艺是最为适合的提浓工艺。In order to obtain more helium resources more economically and ensure China's national economic security,three kinds of common helium-containing natural gas enrichment process in recent years,namely cryogen,membrane-cryogenic and membrane separation,are simulated to provide a useful reference for the economic utilization of low-grade helium-containing gas fields in China.It is found through simulation that as for natural gas with a helium content of 0.0416%in volume,the membrane separation technology can greatly reduce the energy consumption of the helium enrichment process,and exhibits the lowest unit consumption and the highest helium yield among these three enrichment processes.Therefore,at present,the membrane separation process is the most suitable enrichment process for low-grade helium-containing natural gas.
