1-7. (canceled)
A method for producing chilled water, at least one CO2-lean gas and one or more CO2-rich primary fluids from a process fluid containing CO2 and at least one compound more volatile than CO2 and industrial water, comprising the following steps:
- a) separating said process fluid into at least said CO2-lean gas and said CO2-rich primary fluids;
- and
- b) cooling said industrial water by exchange of heat with a non-zero fraction of said CO2-lean gas so as to obtain said chilled water;
- wherein, in step b), said exchange of heat is performed in a direct-contact tower.
