Abstract
The invention relates to a method for treating a gas stream comprising combustion fumes containing CO2 in an initial proportion, water vapor, one or more volatile acid compounds, and one or more additional impurities selected from among oxygen, nitrogen and argon, comprising the steps of: i) compressing the gas stream to a final pressure of 1 bar to 74 bar absolute; ii) cooling the gas stream to a temperature of around −10° C. to around −130° C. and eliminating at least one additional impurity; and iii) recovering a CO2-enriched gas stream containing a final proportion of CO2 greater than the initial proportion of CO2 in the stream to be treated. In addition, the method comprises, prior to step i), a step of pre-drying the stream for removing therefrom at least a portion of the water vapor which it contains.
