Title (EN) CARBON DIOXIDE RECOVERY METHOD USING CRYO-CONDENSATION
(FR) PROCEDE DE CAPTURE DU DIOXYDE DE CARBONE PAR CRYO-CONDENSATION
Abstract:
(EN) Disclosed is a method for producing at least one gas having a low CO2 concentration and one or more primary fluids having a high CO2 concentration from a fluid which is to be treated and contains CO2 and at least one compound that is more volatile than CO2. Said method comprises the following steps: a) the fluid to be treated is subjected to a first cooling process using heat exchange without the fluid undergoing a change of state; b) at least some of the fluid to be treated and cooled in step a) is cooled a second time such that a solid is obtained which contains mainly CO2 and at least the gas having a low CO2 concentration; and c) a step in which at least some of said solid is liquefied such that the one or more primary fluids having a high CO2 concentration are obtained. The disclosed method is characterized in that at least part of the first cooling process in step a) is carried out by heating at least some of the one or more primary fluids having a high CO2 concentration.
(FR) Procédé de production d'au moins un gaz pauvre en CO2 et d'un ou plusieurs fluides primaires riches en CO2 à partir d'un fluide à traiter comprenant du CO2 et au moins un composé plus volatil que le CO2, mettant en œuvre : a) un premier refroidissement dudit fluide à traiter par échange de chaleur sans changement d'état; b) un deuxième refroidissement d'au moins une partie dudit fluide à traiter refroidi à l'étape a) de manière à obtenir au moins un solide comprenant majoritairement du CO2 et au moins ledit gaz pauvre en CO2; et c) une étape comprenant la liquéfaction d'au moins une partie dudit solide et permettant d'obtenir lesdits un ou plusieurs fluides primaires riches en CO2; caractérisé en ce qu'au moins une partie dudit premier refroidissement opéré à l'étape a) est obtenue par réchauffement d'au moins une partie desdits un ou plusieurs fluides primaires riches en CO2.
