摘要：
The invention relates to a method for treating a gas stream comprising combustion fumes containing CO
2 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 CO
2 -enriched gas stream containing a final proportion of CO
2 greater than the initial proportion of CO
2 in the stream to be treated. In addition, the method comprises, prior to step i), a step of predrying the stream for removing therefrom at least a portion of the water vapor which it contains. The invention further relates to equipment for implementing the method. The invention can be used for treating oxycombustion fumes.
