The invention relates to a method for producing at least one gas lean in CO2 and one or more primary fluids rich in CO2 from a fluid to be processed that contains CO2 and at least one compound more volatile than CO2, implementing: a) a first cooling of the fluid to be processed by heat exchange without state modification; b) a second cooling of a at least a portion of the fluid to be processed cooled during step a) in order to obtain at least one solid mainly containing CO2 and at least one gas lean in CO2; and c) a step including the liquefaction and/or sublimation of at least a portion of said solid in order to obtain said one or more CO2-rich primary fluids; wherein the method is characterised in that step b) is carried out in at least one expansion turbine, the solid being formed inside said turbine.
