A CO2 separation unit for recovering CO2 from a CO2-containing gas by using a solid CO2 capturing material, in which the amount of used steam is decreased: the unit comprising a capturing material container (1) having a CO2 capturing material for capturing CO2, a first pipeline (2a) for allowing the CO2-containing gas to flow therethrough into the capturing material container (1), a second pipeline (2b) for allowing a gas from which CO2 has been removed by the CO2 capturing material to be discharged therethrough from the capturing material container (1), a third pipeline (2c) for introducing a steam-containing gas to the inside of the capturing material container (1), a fourth pipeline (2d) for allowing a desorbed CO2-containing gas desorbed from the CO2 capturing material, while the steam-containing gas flows in the container, to be discharged therethrough from the capturing material container (1), wherein the unit further includes a compressor (4a) for compressing steam, a fifth pipeline (2e) for connecting the capturing material container (1) with a suction port of the compressor (4a), and a sixth pipeline (2f) for connecting a discharge port of the compressor (4a) with the third pipeline (2c). |

1. A CO2 separation unit for recovering CO2 from a CO2 containing gas, the unit comprising:
a capturing material container having a CO2 capturing material for capturing CO2; a first pipeline for allowing the CO2-containing gas to flow therethrough into the capturing material container; a second pipeline for allowing a gas from which CO2 has been removed by the CO2 capturing material to be discharged therethrough from the capturing material container; a third pipeline for introducing a steam-containing gas to the inside of the capturing material container; and a fourth pipeline for allowing a desorbed CO2-containing gas desorbed from the CO2 capturing material, while the steam-containing gas flows in the container, to be discharged therethrough from the capturing material container, the unit further comprising: a compressor for compressing steam, a fifth pipeline for connecting the capturing material container with a suction port of the compressor, and a sixth pipeline for connecting a discharge port of the compressor with the third pipeline. |
