摘要：
A method of purifying a gas composed of a product gas and one or more impurity gases, comprising:
- combining a first feed stream (115) with a second stream (108) thereby forming a combined feed stream (404),
- introducing the combined feed stream (404) into a first pressure swing adsorption device (405), thereby producing a first high purity gas stream (407) and a first off-gas stream (406), and
- introducing the first off-gas stream (406) into a membrane separation device (104), thereby producing a gas stream lean in high purity gas stream (105) and a permeate stream (106).
