Title (EN) CO2 RECOVERY METHOD USING CRYO-CONDENSATION
(FR) PROCÉDÉ DE CAPTURE DU CO2 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 and/or sublimed such that the one or more primary fluids having a high CO2 concentration are obtained. The disclosed method is characterized in that at least some of the cold required for the first cooling process and/or the second cooling process is supplied by one or more refrigeration cycles, each of which includes at least one quasi isentropic expansion of a gas.
(FR) Procédé de production d'au moins un gaz pauvre en C02 et d'un ou plusieurs fluides primaires riches en C02 à partir d'un fluide à traiter comprenant du C02 et au moins un composé plus volatil que le C02, mettant en œuvre : a) un premier refroidissement dudit fluide à traiter par échange de chaleur sans changement d'état; b) un second 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 C02 et au moins ledit gaz pauvre en C02; et c) une étape comprenant la liquéfaction et/ou la sublimation d'au moins une partie dudit solide et permettant d'obtenir lesdits un ou plusieurs fluides primaires riches en C02; ledit procédé étant caractérisé en ce qu'au moins une partie du froid nécessaire pour réaliser ledit premier refroidissement et/ou ledit second refroidissement est fournie par un ou plusieurs cycles frigorifiques comprenant chacun au moins une détente quasi isentropique d'un gaz.
