Definitions

the present invention relates to a process for obtaining solutions with a high content of dissolved gas, the solutions obtained by this process and an installation for implementation,
a process has been found which makes it possible to obtain a regular oroduction of a solvent / carbon dioxide mixture which can reach high concentrations of 25 to 30% by weight, at a temperature in the region of 20 ° C. and at a pressure lower than the vapor pressure of carbon dioxide at the same temperature.
hydrochlorofluorinated hydrocarbon mixture with a high concentration of carbon dioxide is compressed under high pressure for their subsequent use.
chlorofluorocarbons suitable for carrying out the process are the products known under the trademark "Freon”, in particular “dichlorodifluoroinethane CCl 2 F 2 ", designated under the trademark "Freon 12".
the compressed “Freon” is sub-cooled in the cold exchanger called the cooler exchanger (5) on the inlet pipe to "Freon” (4).
the inlet temperature varies between - 10 ° C and + 50 ° C, and the minimum outlet temperature is - 10 ° C; the instantaneous flow being 500 kg / hour.
the cold exchanger on the pipe is bathed in a thermostatically controlled bath (6) of a refrigeration unit (7) which can lower the temperature down to - 10 ° C.
the temperature of the thermostatically controlled bath is controlled and regulated by means of the temperature regulator (8).
the sub-cooled “Freon” circulates inside the insulated pipe (9), crosses the valve (10) controlled by the level regulator (11), liquid hydrocarbon in the dissolution zone, then always under insulated pipe is routed to the spray nozzle (12 A), located at the top of the saturator (13).
This spray nozzle can be of any suitable type, such as the swirl type with full cone and impact diameter of 15 to 50 cm, with a high flow rate of 500 kg / hour under a differential pressure of 10 bars.
the saturator body (13), the volume of which is a function of the desired flow rate, can be of cylindrical shape, for example 2 meters high and 200 millimeters in diameter, resistant to a test pressure of 50 bars.
the saturator is: fitted with pressure control means via the display manometer and low and high pressure alarm pressure switch (16) and the purge valve and safety valve (17), calibrated at 35 bars, both located at the top of the saturator (13). It is also provided with means for controlling the temperature of the liquid in the saturator, by means of the temperature probe (18); as well as means for controlling and regulating the level of the "Freon", in the saturator, by means of the level regulator (11).
the saturator is surrounded by thermal insulation (13a).
Carbon dioxide circulates in line (23), fitted with a non-return valve or a high anti-siphon point, shown in (24), the two means being able to be associated.
This pipe (24) penetrates to the lower part of the saturator body (13) where it is extended by a perforated ramp (25) intended for the boiling under pressure of carbon dioxide in the liquid “Freon” (26).
the temperature of the "Freon” solution containing C0 2 is + 10 ° C.
This solution with a high concentration of dissolved C0 2 is drawn off by the heat-insulated pipe (27), at the bottom of the saturator (13).
