CO2 RECOVERY SYSTEM

摘要

The present invention has: a CO2 absorption tower (16) that brings a cooled CO2-containing exhaust gas (12) into contact with a CO2-absorption solution (15) that absorbs CO2, thereby removing the CO2 from said exhaust gas (12); an absorption-solution regeneration tower (18) that releases CO2 from the CO2-absorption solution that has absorbed CO2 (rich solution) (17), thereby regenerating the absorption solution (15); and a lean-solution temperature-reduction means (50) that recovers heat from a lean solution (15) discharged from the absorption-solution regeneration tower (18).
