| Zusammenfassung: | To provide a gas concentration method and a gas concentration device where a large volume storage tank is not needed and power consumption can be suppressed.SOLUTION: A gas concentration device 100 concentrating target gas comprises: a gas separation membrane module 3 including a gas separation membrane 1 and a storage container 2; a gas supply line L1 supplying first mixed gas G1 containing the target gas to the gas separation membrane module 3; a gas recovery line L2 taking second mixed gas G2 containing the target gas out from the gas separation membrane module 3; a gas discharge line L3 discharging exhaust gas G3 from the gas separation membrane module 3; and a raw material gas line L0 supplying raw material gas G0 to the gas supply line L1. The raw material gas G0 from the raw material gas line L0 and the second mixed gas G2 from the gas recovery line L2 are supplied in the gas supply line L1. The gas concentration device and a gas concentration method are provided.SELECTED DRAWING: Figure 1
【課題】大容量の貯蔵タンクが不要で、電力消費を抑制できるガス濃縮方法及びガス濃縮装置を提供する。【解決手段】目的ガスを濃縮するガス濃縮装置であって、ガス分離膜１及び収納容器２を含むガス分離膜モジュール３と、目的ガスを含む第１の混合ガスＧ１をガス分離膜モジュール３に供給するガス供給ラインＬ１と、目的ガスを含む第２の混合ガスＧ２をガス分離膜モジュール３から取り出すガス回収ラインＬ２と、排気ガスＧ３をガス分離膜モジュール３から排出するガス排出ラインＬ３と、ガス供給ラインＬ１に原料ガスＧ０を供給する原料ガスラインＬ０と、を備え、ガス供給ラインＬ１には、原料ガスラインＬ０からの原料ガスＧ０及びガス回収ラインＬ２からの第２の混合ガスＧ２が供給される、ガス濃縮装置１００、並びにガス濃縮方法。【選択図】図１ |
