要約
(EN) An aspect of the present invention is a gas treatment method including: an absorption step of bringing a gas to be treated, which contains carbon dioxide and a sulfur compound, into contact with an absorption liquid to be phase-separated by carbon dioxide absorption, to cause the absorption liquid to absorb the carbon dioxide and the sulfur compound; and a first release step of heating the absorption liquid brought into contact with the gas to be treated to a temperature equal to or higher than a temperature at which the carbon dioxide absorbed by the absorption liquid is released from the absorption liquid and lower than a temperature at which the sulfur compound absorbed by the absorption liquid is released from the absorption liquid, to release the carbon dioxide from the absorption liquid.
(FR) Un aspect de la présente invention est un procédé de traitement de gaz comprenant : une étape d'absorption consistant à amener un gaz à traiter, qui contient du dioxyde de carbone et un composé soufré, en contact avec une solution d'absorption qui effectue une séparation de phase par absorption de dioxyde de carbone, ce qui amène le dioxyde de carbone et le composé de soufre à être absorbés par la solution d'absorption; et une première étape de libération consistant à chauffer la solution d'absorption qui a été mise en contact avec le gaz à traiter à au moins une température à laquelle le dioxyde de carbone absorbé dans la solution d'absorption est libéré de la solution d'absorption, mais inférieure à la température à laquelle le composé de soufre absorbé dans la solution d'absorption est libéré de la solution d'absorption, libérant ainsi le dioxyde de carbone de la solution d'absorption.
