The solution-saturation (13,26) is produced in a countercurrent manner under low pressure of the gas (19) in a chlorofluorohydrocarbon (1) which is sprayed (12A,12B), previously compressed (3), and supercooled (5) to a temperature in the neighborhood of or lower than the temperature chosen for the chlorofluorohydrocarbon dissolved gas mixture at the outlet (30), the first gas-liquid chlorofluorohydrocarbon contact being effected by a bubbling (25) under pressure of the gas in the chlorofluorohydrocarbon (26) under conditions of temperature and pressure lower than the critical conditions, with a strict thermal regulation (31) throughout the dissolving stage so as to effect it below the critical conditions, thereafter the chlorofluorohydrocarbon mixture having a high content of dissolved gas is compressed (28A,28B) under high pressure. Application in the chlorofluorohydrocarbon solutions and in particular dichlorodifluoromethane having a high content of carbon dioxide.
