Beschreibung
Zusammenfassung:	This carbon dioxide recovery system comprises: a first distillation column in which an absorption liquid that has absorbed carbon dioxide is heated so as to let carbon dioxide diffuse therefrom; a first reboiler which performs heat transfer between vapor and the absorption liquid extracted from the first distillation column; and a hydrogen feed unit which feeds hydrogen to the absorption liquid in the first reboiler, or to the absorption liquid that has flown out of the first reboiler.
