Title (EN) CARBON DIOXIDE RECOVERY SYSTEM
(FR) SYSTÈME DE RÉCUPÉRATION DE DIOXYDE DE CARBONE
(JA) 二酸化炭素回収システム
Abstract:
(EN) The purpose of the present invention is to inhibit a CO2 absorption tower in which a CO2 trapping agent is contained from decreasing in CO2 trapping amount due to an increase in the internal temperature thereof caused by the heat of CO2 trapping reaction. In a CO2 recovery system for recovering CO2 from a CO2-containing gas, CO2 trapping agents of two or more different kinds are disposed in the absorption tower.
(FR) La présente invention a pour but d'empêcher une tour d'absorption de CO2 dans laquelle un agent de piégeage de CO2 est contenu, de présenter une quantité de piégeage de CO2 diminuée à cause d'une augmentation de la température interne de celle-ci provoquée par la chaleur de la réaction de piégeage de CO2. Dans un système de récupération de CO2 pour récupérer du CO2 à partir d'un gaz contenant du CO2, des agents de piégeage de CO2 d'au moins deux différentes sortes sont disposés dans la tour d'absorption.
(JA)  CO2捕捉剤を収容したCO2吸収塔内において、CO2捕捉反応熱のために吸収塔内の温度が上昇することによりCO2捕捉量が低下することを抑制する。CO2含有ガスからCO2を回収するCO2回収システムにおいて、異なる二種類以上のCO2捕捉剤を吸収塔に設置する。
