Abstract
An acidic gas separation module 10, which improves gas separation efficiency and reduces pressure loss, includes: a permeating gas collecting tube 12 having tube walls in which through holes 12A are formed; a layered body 14 that has at least an acidic gas separation layer 32 and that is wound on the permeating gas collecting tube 12; and telescope prevention plates 18 (a gas supply side 18A and a gas discharge side 18B) provided at both end faces in an axial direction of the wound layered body 14, wherein the ratio (D2/D1) of the open area ratio D2 of the telescope prevention plate on the gas discharge side 18B relative to the open area ratio D1 of the telescope prevention plate on the gas supply side 18A is from 0.5 to 0.9. An acidic gas separation device includes the acidic gas separation module 10.
