Title (EN) METHOD FOR TRAPPING CARBON DIOXIDE BY CRYOCONDENSATION
(FR) PROCEDE DE CAPTURE DU DIOXYDE DE CARBONE PAR CRYO-CONDENSATION
Abstract:
(EN) The invention relates to a method for producing at least one gas lean in CO2 and one or more fluids rich in CO2 from a fluid to be processed including CO2 and at least one compound more volatile than CO2, wherein said method comprises: a) cooling, by cryocondensation, at least a portion of said fluid to be processed in at least one container so as to obtain at least one solid mainly containing CO2 and at least said gas lean in CO2; b) extracting at least a portion of the solid produced during step a) from said container; and c) liquefying and/or subliming a at least a portion of said solid extract during step b) in order to obtain one or more fluids rich in CO2; characterised in that the time intervals during which step b) is implemented are included in the time intervals during which said step a) is implemented.
(FR) Procédé de production d'au moins un gaz pauvre en CO2 et d'un ou plusieurs fluides riches en CO2 à partir d'un fluide à traiter comprenant du CO2 et au moins un composé plus volatil que le CO2, ledit procédé mettant en œuvre : a) un refroidissement dans au moins une enceinte d'au moins une partie dudit fluide à traiter de manière à obtenir au moins un solide comprenant majoritairement du CO2 par cryo-condensation et au moins ledit gaz pauvre en CO2; b) une extraction de ladite enceinte d'au moins une partie dudit solide formé à l'étape a); et c) une liquéfaction et/ou une sublimation d'au moins une partie dudit solide extrait à l'étape b) de manière à obtenir un ou plusieurs fluides riches en CO2; caractérisé en que les intervalles de temps pendant lesquels ladite étape b) est mise eu œuvre sont inclus dans les intervalles de temps pendant lesquels ladite étape a) est mise en œuvre.
