Document Type and Number:
WIPO Patent Application WO/2016/076091
Kind Code:
A1
Abstract:
This apparatus for separating CO2 in a gas is provided with: a first membrane separator 13A that performs membrane separation of CO2 from a starting material gas 11 by means of a separation membrane 13a; a first permeated gas discharge line L12 that discharges a first permeated gas 14A, which has permeated through the membrane separation of the first membrane separator 13A; a first non-permeated gas discharge line L13 that discharges a first non-permeated gas 15A, which has not permeated through the membrane separation of the first membrane separator 13A; a second membrane separator 13B that is provided in the downstream of the first membrane separator 13A and performs further membrane separation of CO2 from the first non-permeated gas 15A by means of a separation membrane 13b; a second permeated gas discharge line L14 that discharges a second permeated gas 14B, which has permeated through the membrane separation of the second membrane separator 13B; and a second permeated gas return line L15 that is branched from a part of the second permeated gas discharge line L14 and returns the second permeated gas 14B to the starting material gas 11 side.
