СИСТЕМА ДЛЯ ИЗВЛЕЧЕНИЯ CO2 И СПОСОБ ИЗВЛЕЧЕНИЯ CO2

摘要

A CO 2 recovery system (10A) includes an absorption tower (13) and a regeneration tower (15). CO 2 rich solution (14) is produced in the absorption tower (13) by absorbing CO 2 from CO 2 -containing gas (11). The CO 2 rich solution (14) is conveyed to the regeneration tower (15) where lean solution (16) is produced from the rich solution (14) by removing CO 2 . A compressor (44-1, 44-2) compresses CO 2 (41) that is removed from the rich solution (14) and discharged through a head of the regeneration tower (15). Heat is generated while the compressor compresses the CO 2 . A heat supplying unit supplies the heat to the regeneration tower (15) for heating the lean solution (16).
