Abstract
(EN) An apparatus for recovering CO2 having an absorbing tower (13) for contacting a CO2-containing gas (11) containing CO2 with a CO2-absorbing fluid (12) absorbing CO2, for the removal of CO2, and a regenerating tower (15) for regenerating a rich solution (14) having absorbed CO2, and reutilizing, in the absorbing tower (13), a lean solution (16) having been removed of CO2 in said regenerating tower (15), which comprises a regeneration heater (18) for withdrawing a lean solution (16) recovered in the vicinity of the bottom of the regenerating tower (15) to the outside thereof and subjecting the lean solution to the heat-exchange with a high temperature steam (17), and a steam-condensed water heat exchanger (21) being provided in a rich solution supplying line (20) supplying a rich solution (14) to the regenerating tower (15) from the absorbing tower (13) for heating said rich solution (14) by the use of the remaining heat of the steam-condensed water (19) from the above regeneration heater (18).
(FR) Appareil pour récupérer du CO2 ayant une tour d'absorption (13) pour mettre en contact un gaz contenant du CO2 (11) contenant du CO2 avec un fluide absorbant le CO2 (12) absorbant le CO2 pour enlever le CO2 et une tour de régénération (15) pour régénérer une solution riche (14) ayant du CO2 absorbé et réutiliser, dans la tour d'absorption (13), une solution pauvre (16) ayant été appauvrie en CO2 dans ladite tour de régénération (15), lequel comprend un réchauffeur de régénération (18) pour soutirer une solution pauvre (16) récupérée aux environs du fond de la tour de régénération (15) vers l'extérieur de celle-ci et soumettre la solution pauvre à un échange de chaleur avec une vapeur à haute température (17) et un échangeur de chaleur à l'eau condensée de la vapeur (21) étant disposé dans la ligne d'alimentation en solution riche (20) introduisant une solution riche (14) dans la tour de régénération (15) à partir de la tour d'absorption (13) pour chauffer ladite solution riche (14) grâce à l'utilisation de la chaleur résiduelle de l'eau condensée de la vapeur (19) provenant du réchauffeur de régénération (18) ci-dessus.
(JA)  本発明にかかるCO2回収装置は、CO2を含有するCO2含有ガス(11)とCO2を吸収するCO2吸収液(12)とを接触させてCO2を除去する吸収塔(13)と、CO2を吸収したリッチ溶液(14)を再生する再生塔(15)と、該再生塔(15)でCO2を除去したリーン溶液(16)を吸収塔(13)で再利用するCO2回収装置であって、再生塔(15)の塔底部近傍に回収されたリーン溶液(16)を外部へ抜き出して高温スチーム(17)により熱交換する再生加熱器(18)と、吸収塔(13)から再生塔(15)にリッチ溶液(14)を供給するリッチ溶液供給管(20)に設けられ、前記再生加熱器(18)からのスチーム凝縮水(19)の余熱により該リッチ溶液(14)を加熱するスチーム凝縮水熱交換器(21)とを具備してなる。
