Title:
二酸化炭素分離回収システム及び方法
Document Type and Number:
Japanese Patent JP7123749
Kind Code:
B2
Abstract:
A carbon dioxide separation recovery method includes: bringing a particulate carbon dioxide adsorbent and a treatment target gas containing carbon dioxide into contact with each other to make the carbon dioxide adsorbent adsorb the carbon dioxide contained in the treatment target gas; and bringing the carbon dioxide adsorbent which has adsorbed the carbon dioxide and desorption steam into contact with each other to desorb the carbon dioxide from the carbon dioxide adsorbent, and thereby, regenerate the carbon dioxide adsorbent and recover the desorbed carbon dioxide. The step of recovering the carbon dioxide includes utilizing a recovery gas as a heat source of a heat exchanger, the recovery gas containing the desorption steam which has contacted the carbon dioxide adsorbent and the carbon dioxide which has been desorbed from the carbon dioxide adsorbent.
