A process for compressing a CO2-rich fluid containing water. The CO2-rich fluid is compressed in a compressor; upstream of the compression step, an antifreeze is mixed with the CO2-rich fluid containing water. The CO2-rich fluid containing antifreeze is cooled, water is separated from the cooled fluid and the water-depleted cooled fluid is compressed in the compressor, wherein the CO2-rich fluid containing water is sent to a scrubbing column fed, preferably at the top, with a water/antifreeze mixture, where it cools and is separated from the water, the water-depleted cooled fluid is extracted from the top of the column; a water/antifreeze mixture in the column is extracted at a level below the top; the mixture is cooled using the refrigeration from an apparatus for cooling and/or purifying the cooled fluid compressed in the compressor and the fluid is returned to the top of the column.
