Title
(DA) APPARAT OG FREMGANGSMÅDE TIL GENVINDING AF CO2
Abstract
(EN) A CO 2 recovery system according to the present invention includes an absorption tower (13) that contacts CO 2 -containing gas (11) containing CO 2 with a CO 2 -absorbing solution (12) absorbing CO 2 to remove CO 2 ; and a regeneration tower (15) that regenerates a rich solution (14) having absorbed CO 2 , and reuses a lean solution (16), obtained by removing CO 2 from the rich solution in the regeneration tower (15), in the absorption tower (13). The CO 2 recovery system also includes a regeneration heater (18) that extracts the lean solution (16) recovered near a bottom portion of the regeneration tower (15) to the outside, and heat-exchanges the lean solution (16) with high-temperature steam (17); and a steam-condensate heat exchanger (21) that is provided in a rich-solution supply pipe (20) for supplying the rich solution (14) from the absorption tower (13) to the regeneration tower (15) and heats the rich solution (14) with the residual heat of steam condensate (19) fed from the regeneration heater (18).
