System and method for recovering CO2

摘要

A CO 2 recovery system includes an absorption tower (13) that receives CO 2 -containing gas (11) and CO 2 -absorbing solution (12), and causes the CO 2 -containing gas (11) to come in contact with the CO 2 -absorbing solution (12) to produce CO 2 rich solution (14), and a regeneration tower (15) that receives the rich solution (14) and produces lean solution (16) from the rich solution (14) by removing CO 2 from the rich solution (14). A heating member (30) is provided in the regeneration tower (15). The heating member (30) heats the rich solution (14) in the regeneration tower (15) with steam generated when regenerating the rich solution (14) in the regeneration tower (15).
