Abstract

In a method for compressing a water-containing CO2-rich fluid wherein the CO2-rich fluid is compressed in a compressor located upstream from the compression step, an antifreeze agent is injected into the water-containing CO2-rich fluid in order to lower the water solidification temperature. The antifreeze agent-containing CO2-rich fluid is frozen, water is extracted from the frozen fluid, and the frozen fluid is compressed in the compressor.
