A carbon dioxide separation and recovery system includes: an adsorption reactor, which adsorbs, by an adsorbent, carbon dioxide contained in a to-be-treated gas, discharges the to-be-treated gas from which the carbon dioxide has been removed, and discharges the adsorbent that has adsorbed the carbon dioxide; a desorption reactor, which receives the adsorbent discharged from the adsorption reactor, condenses desorbing steam on the adsorbent to cause carbon dioxide to desorb from the adsorbent, and then discharges the adsorbent; and an adsorbent dryer, which receives the adsorbent discharged from the desorption reactor, dries the adsorbent until a water content ratio thereof becomes a predetermined value greater than or equal to a water content ratio limit by causing, with use of a drying gas, condensation water contained in the adsorbent to evaporate as steam, and then discharges the adsorbent. |

1. A carbon dioxide separation and recovery system for separating carbon dioxide from a to-be-treated gas containing the carbon dioxide with use of a carbon dioxide adsorbent and regenerating the adsorbent after the adsorbent has adsorbed the carbon dioxide, the carbon dioxide separation and recovery system comprising:
an adsorption reactor that adsorbs, by the adsorbent, carbon dioxide contained in the to-be-treated gas and discharges the to-be-treated gas from which the carbon dioxide has been removed; a desorption reactor that condenses desorbing steam on the adsorbent that has adsorbed the carbon dioxide to cause the carbon dioxide to desorb from the adsorbent; and an adsorbent dryer that dries the adsorbent until a water content ratio thereof becomes a predetermined value greater than or equal to a water content ratio limit by causing, with use of a drying gas, condensation water contained in the adsorbent from which the carbon dioxide has desorbed to evaporate as steam. |
