Title
(EN) CALCINATION PROCESS
(FR) PROCÉDÉ DE CALCINATION
Abstract
(EN)
A process comprising the following steps:a) calcination of a metal carbonate by combustion of a fuel in the presence of a mixture of oxygen, water vapour and carbon dioxide, to generate a metal oxide, water vapour, carbon dioxide and heat;b) using the heat generated to drive an oxygen generation reaction; and c) use of the oxygen generated in step b) in calcination step a). The use of the process on carbon dioxide sequestration and/or in oxygen generation.
(FR)
La présente invention concerne un procédé comprenant les étapes suivantes : a) la calcination d'un carbonate de métal par combustion d'un combustible en présence d'un mélange d'oxygène, de vapeur d'eau et de dioxyde de carbone, pour générer un oxyde de métal, de la vapeur d'eau, du dioxyde de carbone et de la chaleur ; b) l’utilisation de la chaleur générée pour entraîner une réaction de génération d'oxygène ; et c) l’utilisation de l'oxygène généré à l'étape b) dans l'étape a) de calcination. L'invention concerne également l'utilisation du procédé dans la séquestration de dioxyde de carbone et/ou dans la génération d'oxygène.
