PROBLEM TO BE SOLVED: To cut cost required for gas separation even with a simple configuration.SOLUTION: A gas separation device 100 includes: an absorption tower 110 that includes an absorbent 120 absorbing oxygen in an environment of a predetermined pressure and a predetermined temperature, and at least a part of which is exposed to an atmosphere of a temperature higher than an ordinary temperature; a first supply path 132 introducing air blown in from an air blower 130 into the absorption tower 110, and a second supply path 136 introducing the air lower in flow rate than the air introduced by the first supply path 132 into the absorption tower 110; a separated-gas discharge unit 140 connected to the absorption tower 110, and discharging separated gas; a first heat exchange unit 150 exchanging heat between the separated gas discharged from the absorption tower 110 and the air introduced from the first supply path 132 into the absorption tower 110; an oxygen discharge unit 160 depressurizing an interior of the absorption tower 110, desorbing the oxygen from the absorbent 120, and discharging the oxygen from the absorption tower 110; and a second heat exchange unit 170 exchanging the heat between the oxygen and the air introduced from the second supply path 136 into the absorption tower 110. |
