Title
(EN) IMPROVEMENTS IN THE RECOVERY OF CARBON DIOXIDE
(FR) RÉCUPÉRATION DU DIOXYDE DE CARBONE PERFECTIONNÉE
Abstract
(EN)
A process for removing the carbon dioxide from a flue gas exiting from a fossil fuel combustion reaction, wherein the process includes the following steps: a. cooling the flue gas to below 50°C by directly contacting the flue gas with a counter current stream of liquid water; and, b. removing the carbon dioxide from the flue gas by directly contacting the flue gas with a scrubbing agent.
(FR)
L'invention concerne un procédé permettant d'éliminer du dioxyde de carbone d'un gaz brûlé issu d'une réaction de combustion de combustible fossile. Le procédé consiste à : a) refroidir le gaz brûlé à moins de 50 °C par contact direct avec un écoulement à contre-courant d'eau liquide; et b) éliminer le dioxyde de carbone du gaz brûlé par contact direct avec un agent de lavage.
