Title
(EN) Apparatus and method for recovering CO2
Abstract
(EN) A CO2 recovery system including an absorption tower that receives C02-containing gas and C02-absorbing solution, and causes the C02-containing gas to come in contact with the C02-absorbing solution to produce CO2 rich solution, and a regeneration tower that receives the rich solution and produces lean solution from the rich solution by removing CO2 from the rich solution, the CO2 recovery system comprising: a semi-lean-solution extraction path that extracts semi-lean solution from a middle portion of the regeneration tower and returns extracted semi-lean solution to the middle portion of the regeneration tower; a lean-solution supply member that extracts the lean solution from the regeneration tower and conveys extracted lean solution to the absorption tower; and a lean-solution heat exchanger that is provided in the semi-lean-solution extraction path and the lean-solution supply member, and heats the semi-lean solution in the semi lean-solution extraction path with the lean solution in the lean-solution supply member.
