摘要： The present provides a helium gas separation and recovery process involving cryogenic fractionation process, which comprises cooling a dehydrated high-pressure gas stream while maintain velocity and pressure of the stream; reducing pressure of the dehydrated high-pressure gas stream via a Joule-Thompson's process to obtain a partially liquefied gas stream; and iii) subjecting the partially liquefied gas stream to at least one gas-liquid separation process to obtain at least one liquid stream and a gaseous stream comprising helium, and a residual amount of the gaseous components; recycling the liquid stream obtained in step iii) for use as cooling refrigerant to cool the dehydrated high-pressure gas stream; and purifying the unrefined helium gas stream using pressure swing adsorption (PSA) and/or membrane separation process to obtain a helium product stream having a purity of 98.0 mole % or more.
