Abstract
(EN)
This method for separating and recovering carbon dioxide includes: a step for bringing a particulate carbon dioxide adsorbent into contact with a carbon dioxide-containing gas to be treated, and adsorbing carbon dioxide contained in the gas to be treated onto the carbon dioxide adsorbent; and a step for regenerating the carbon dioxide adsorbent and recovering desorbed carbon dioxide, by bringing a carbon dioxide adsorbent in which carbon dioxide is adsorbed, into contact with desorption vapor, to desorb carbon dioxide from the carbon dioxide adsorbent. The step for recovering carbon dioxide includes using, as a heat source of the heat exchanger, the recovered gas which contains: desorption vapor which has contacted the carbon dioxide adsorbent; and carbon dioxide which has been desorbed from the carbon dioxide adsorbent.

Ce procédé de séparation et de récupération de dioxyde de carbone comprend : une étape consistant à amener un adsorbant de dioxyde de carbone particulaire en contact avec un gaz contenant du dioxyde de carbone à traiter, et à adsorber le dioxyde de carbone contenu dans le gaz à traiter sur l'adsorbant de dioxyde de carbone; et une étape de régénération de l'adsorbant de dioxyde de carbone et de récupération de dioxyde de carbone désorbé, par mise en contact d'un adsorbant de dioxyde de carbone dans lequel du dioxyde de carbone est adsorbé, en contact avec la vapeur de désorption, pour désorber le dioxyde de carbone de l'adsorbant de dioxyde de carbone. L'étape de récupération de dioxyde de carbone consiste à utiliser, en tant que source de chaleur de l'échangeur de chaleur, le gaz récupéré qui contient : de la vapeur de désorption qui a mis en contact avec l'adsorbant de dioxyde de carbone; et du dioxyde de carbone qui a été désorbé de l'adsorbant de dioxyde de carbone.

二酸化炭素分離回収方法は、粒子状の二酸化炭素吸着材と二酸化炭素を含む処理対象ガスとを接触させて、処理対象ガスに含まれる二酸化炭素を二酸化炭素吸着材に吸着させるステップと、二酸化炭素を吸着した二酸化炭素吸着材と脱着用蒸気とを接触させて、二酸化炭素吸着材から二酸化炭素を離脱させることにより当該二酸化炭素吸着材を再生するとともに、離脱した二酸化炭素を回収するステップとを含む。二酸化炭素を回収するステップが、二酸化炭素吸着材と接触した脱着用蒸気と当該二酸化炭素吸着材から離脱した二酸化炭素とを含む回収ガスを熱交換器の熱源として利用することを含む。
