Definitions
- the present invention relates to the distribution of alcohol-based fuel, including ethanol, bioethanol, butanol, methanol and mixtures thereof, for example with hydrocarbons.
- the present invention relates to a fuel storage installation comprising at least one alcohol-based fuel tank, for example E85, said tank comprising at least fuel withdrawal means, filling means, and a conduit. in communication with a gas manifold that can be in communication with the vents of other fuel storage tanks and the tank of a loading truck.
- the installation comprises means for dehumidifying the gases passing through the vent pipe of the alcohol-based fuel tank, in particular bioethanol, comprising: a refrigerating exchanger intended to freeze the water and to condense the vapors of fuel, or condensates; - Condensate collection means; - Defrosting means and collection of defrost water.
- the dehumidification means may comprise a condensate and defrosting water receiving tank from said exchanger, and two distribution valves for discharging the condensates separately from the water.
- the de-icing means may comprise means for controlling the valves so as to close the condensate discharge valve before defrosting while opening the water discharge valve.
- a gas collection duct can connect the dispensing gun to a fuel tank. All vent lines in each fuel cell can pass through a refrigeration exchanger to condense the fuel vapors.
- the vent pipes of the diesel tank and the biofuel tank can be in communication.
- the invention also relates to a method for dispensing fuel from a fuel storage installation comprising at least one alcohol-based fuel tank, said tank comprising at least fuel withdrawal means, filling means , and a vent pipe in communication with a gas manifold that can be in communication with the vents of other fuel storage tanks and the tank of a cargo truck. According to the method, the following steps are carried out:
- the invention combines the condensation of fuel vapors, hydrocarbon or alcohol-based, for example ethanol, bioethanol, butanol, methanol, their mixtures, for example with hydrocarbons, with the drying of air by the cold. For this we lower the temperature of the air entering the tank to turn the water into frost.
- FIG. 1 shows a bioethanol tank and its filling and emptying circuits
- FIG. 2 is a view showing a service station during filling of its tanks, including a bioethanol tank.
- Figure 3 shows a part of the installation of Figure 2 during emptying of its tanks.
- bioethanol is not limited to this fuel, and extends to any alcohol-based fuel, such as those mentioned above.
- the tank 1 is intended to contain a fuel based on bioethanol. For its filling, it has a pipe 2 which connects to the loading hose of a tanker truck.
- vent gases are collected by means of a manifold 5, an output of which allows to connect a pipe 7 which brings these gases to the tank of the supply truck.
- vent pipe 3 is surmounted by a safety valve 6 for controlling the pressure of the gases in the tank.
- the safety valve 6 operates in both directions of overpressure or depression in the tank.
- the implementation is as follows:
- the fuel molecules contained in the gas are condensed.
- the condensate is sent into a container 8.
- this container can operate on the same principle as a flush.
- a valve 111 opens to evacuate these fuel condensates to a suitable tank via the conduit 110.
- the invention allows, in combination, to recover in liquid form the fuel vapors and to remove the water contained in the gas in contact with a miscible fuel in water.
- a defrost cycle of the machine is started.
- the defrost cycle consists of operating the machine producing cold upside down, following the same principle as reversible air conditioning. Ice in the form of frost melts and flows into the container 8.
- a valve 112 on a specific water discharge conduit 9 opens to discharge the water to a tank, for example the settling tank from the service station.
- the defrosting step can begin with the complete evacuation of the condensates via the duct 110.
- the valve 112 is closed. .
- the system includes programmed periodic defrost cycles, combined with the operation of the exhaust valves 111 and 112.
- FIG. 2 shows a variant in which the system according to the invention is integrated in a set of tanks for gasoline and diesel fuel C1 to C4.
- FIG. 2 shows a service station S comprising four tanks C1, C2, C3, C4, and a bioethanol tank 1, of a storage facility I, each intended to contain a fuel intended to be distributed from volumetizers or "pumps", of which only one, referenced P, is represented.
- the tanks C1, C2 and C3 are intended to contain light fuels, namely "gasoline 98", “gasoline 95".
- the tank C4 is, for its part, intended to contain a heavy fuel, namely diesel, which differs from the light fuels of tanks C1, C2, C3 by its lower volatility.
- the tank 1, according to Figure 1 contains a fuel based on ethanol.
- the tank C1 is being filled from a tank 10 of a delivery truck, as represented by the arrows Fl.
- a discharge pipe 11 connects the tank 10 to the tank C1 in which is disposed for example a not shown gauge.
- a vent pipe 12 has its inlet 12a disposed in the upper portion of the tank C1 to collect the vent gas resulting from the filling operation. The circulation of these vent gases is represented by arrows F2.
- the vent duct 12 is provided, in its current part, with a condenser 13 and is connected, at its outlet orifice 12b, to a manifold 14 provided with a safety valve 15 for venting free the manifold in case of overpressure or gas vacuum.
- the outlet 14A of the manifold 14 is connected by a recycling duct 19 to a gas distribution network 16 inside the tank 10 (more particularly visible in FIG. 3), so that the condenser 13 is integrated in a line collecting the vents of the tank C1 towards the tank, this line being formed by the meeting of the vent pipe 12, the collector 14, the pipe 19 and the network 16.
- the vent gases flowing in the pipe 12 are cooled in the condenser 13 and are thus discharged from their fuel particles which condense and flow to the tank Cl as represented by the arrows F3.
- the condensates circulate in a specific evacuation duct 17 shown in phantom, or, alternatively, flow into the vent duct 12, in particular by means of a capillary, either by simple gravity , or forcibly by means of a pump not shown.
- the exhaust duct 17 is connected to the discharge pipe 11 so as to promote the flow of condensates by Venturi effect caused by the flow of fuel removed from the tank 10.
- the tanks C1, C2, C3 and C4 of the installation I are each equipped with a vent duct 22, 32, 42 opening at the outlet into the manifold 14 which is therefore common to all the vent ducts 12, 22 , 32 and 42, in the sense that gases can pass from any duct to another via this manifold.
- the collector 14 is preferably equipped with gas distribution means passing therethrough, sensitive to the gas pressure prevailing in the various vent pipes 12, 22, 32 and 42: if the pressure prevailing in one of these vent pipes is greater than those prevailing in other conduits, these distribution means balance these gas pressures by allowing a portion of the gas duct pressure to pass into the ducts of lower pressure.
- the vent duct 3 of the tank 1 is connected to the vent duct 42 of the diesel fuel tank.
- vent pipes 22 and 32 associated with tanks C2 and C3 of light fuel are each equipped with a condenser 23 and 33 substantially similar to the condenser 13.
- Each condenser 23 and 33 is connected to an evacuation pipe of condensates 27 and 37, similar to the conduit 17 associated with the condenser 13 and adapted to direct the condensed vapors at the outlet of each condenser respectively to the tanks C2 and C3.
- the vent duct 42 associated with the diesel fuel tank C4 is also equipped with a condenser 43.
- This condenser 43 is implanted in a similar manner to that of the condenser 13 of the duct 12, but is different from this condenser 13 by its dimensioning. More specifically, the cooling capacity of the condenser 43 is significantly lower than that of the condensers 13, 23 and 33.
- the vent duct 3 being connected upstream of the condenser 43, all the gases of the tank 1 pass through said condenser 43 .
- the condenser 43 is connected to a condensate discharge duct 47 which, unlike the ducts 17, 27 and 37, does not direct the condensates towards the tank from which the condensates originate.
- gas vents treated in the condenser but to one of the tanks of light fuels, namely, for example, tanks C1, C2, C3, or tank 1, in Figure 1.
- means for distributing defrost water and condensates 113 are placed on the evacuation line 47.
- the vent pipe 42 of the diesel fuel tank C4 is provided with a valve 20 disposed between the condenser 43 and the manifold 14.
- This valve is preferably calibrated more weakly than the valve 15, for example at -5 mbar instead of -15 mbar, so as to allow the introduction of ambient air into the tank C4 as soon as a depression is formed therein in particular when dispensing fuel from the tank C4 to the pump P .
- the vent pipe 3 also comprises a valve 6.
- its calibration must not allow the introduction of ambient air, but priority is given to the valve 20 so that the air introduced into the tank 1, and C4 passes through an exchanger, for example that referenced 43.
- the condensers 13, 23, 33 and 43 are for example adapted to be supplied with a heat transfer fluid from a cooling unit of this fluid, the latter being selected according to environmental standards in force.
- This unit comprises for example one or more compressors able to cool the fluid supplying the condensers at a temperature between -55 ° C and -25 ° C, preferably between about -45 ° C and -4O 0 C. Details of Conductors of this type are for example given in WO-A-03/006358.
- the installation I further comprises a suction duct 18 opening, at one of its ends, in the tank C1 and, at its opposite end, in a gas collection network of the flow meter P.
- the meter is equipped with fuel dispensing guns, respectively provided, for the light fuel dispensing guns, with a suction nozzle for the fuel vapors released during the filling of the tank of a motor vehicle.
- These suction nozzles collect the gases resulting from the filling of this tank and send them into the conduit 18 so that these vapors are not released into the atmosphere but returned to the tank Cl.
- the conduit 18 and the collection network of the meter P thus form means for recovering gases released during the filling of these tanks, able to meet certain environmental standards. It should be noted that these recovery gases can not reach the tank 1 of bioethanol fuel without passing through at least one exchanger, which guarantees dehumidification of the gases and prohibits an increase in the possible rate of water in the fuel. based on bioethanol stored in the tank 1.
- the fumes of light fuels passing through the common manifold 14, one of the tanks 1, C1, C2 and / or C3 to the tank C4, are at least partially recovered, by means of condenser 43, in the form of condensates discharged to the tank C1 being understood that these condensates could be evacuated as well to any light fuel tank of the installation.
- This passage of fuel vapors is even more marked than the diesel tank is frequently solicited compared to tanks of light fuels.
- the gases that can return to the tank 1 are dehumidified by icing.
- the return of the condensates in one of the tanks of light fuel namely in the tank C1 in the example in the figures
- the concomitant return of cooled gases, freed from most of their light fuel particles , in the tank C4 and, where appropriate, in the tanks C1, C2 and C3 make it possible to avoid sending light fuels into the tank of heavy fuel C4 and to cool the internal gas atmosphere of the tanks, which limits evaporation of fuels in the tanks.
