二氧化碳回收系统
摘要：
本发明提供能够降低胺向大气中的放出量的二氧化碳回收系统。基于实施方式的二氧化碳回收系统(1)具备吸收塔(20)、再生塔(30)和加热部(52)。吸收塔(20)具有将从二氧化碳回收部(20a)排出的燃烧排放气体(3)用第1洗涤液(11)进行洗涤而将燃烧排放气体(3)中伴随的胺回收的第1洗涤部(21)、和将从第1洗涤部(21)排出的燃烧排放气体(3)用第2洗涤液(12)进行洗涤而将燃烧排放气体(3)中伴随的胺回收的第2洗涤部(22)。加热部(52)对第1洗涤液(11)进行加热，使第1洗涤液(11)的温度比二氧化碳回收部(20a)的上端部的温度高、且比第2洗涤液(12)的温度高。
摘要（英）：

A carbon dioxide capture system according to an embodiment includes an absorber, a stripper, and a heater. The absorber includes a first cleaning unit and a second cleaning unit. The first cleaning unit uses first cleaning liquid to clean combustion exhaust gas discharged from a carbon dioxide capturer and captures amine flowing together with the combustion exhaust gas. The second cleaning unit uses second cleaning liquid to clean the combustion exhaust gas discharged from the first cleaning unit and captures amine flowing together with the combustion exhaust gas. The heater heats the first cleaning liquid to a temperature higher than the temperature of an upper portion of the carbon dioxide capturer and of the second cleaning liquid.
