Abstract
A carbon dioxide recovery system is equipped with: a first distillation column for heating an absorption liquid that has absorbed carbon dioxide to release carbon dioxide from the absorption liquid; a first reboiler for exchanging heat between the absorption liquid extracted from the first distillation column and steam; a second reboiler for exchanging heat between the absorption liquid extracted from the first distillation column and a fluid different from both an effluent gas from the first distillation column and the steam; and a first compressor for compressing the fluid before the fluid flows into the second reboiler.
