Definitions
- Fuel storage and distribution facility particularly for motor vehicles.
- the present invention relates to a fuel storage and distribution installation, in particular for motor vehicles.
- the tanks are conventionally filled with different types of fuel. These tanks contain so-called light fuels, such as unleaded gasoline 98 octane (E98), 95 unleaded gasoline octane (E95), the mixture of gasoline and diesel. ethanol (biofuel) as those additives with ethanol up to 10% or up to 85% by volume, called E10 and E85, and so-called heavy fuels, such as oil or diesel.
- light fuels such as unleaded gasoline 98 octane (E98), 95 unleaded gasoline octane (E95), the mixture of gasoline and diesel.
- ethanol (biofuel) as those additives with ethanol up to 10% or up to 85% by volume, called E10 and E85, and so-called heavy fuels, such as oil or diesel.
- VOCs volatile organic compounds
- gasoline vapors from the liquid fuel, in the gas phase in thermodynamic equilibrium in the tank with the liquid phase.
- the gas phase can contain between 40 and 90% by volume of VOCs, some of which are very harmful to human health.
- the gaseous complement is air charged with water vapor or moisture.
- the VOC content is very low.
- Each fuel tank which is generally buried, has a filling means which connects it to the fuel delivery truck, at least one withdrawal means to a distribution device and a conduit. vent which avoids overpressure or depression of this tank. Each vent is generally provided with a valve to balance the pressure of the storage tank according to whether this tank is in depression or in overpressure.
- recovery phase I This recovery is better known under the name “recovery phase I", which has been in place for many years in European countries in particular.
- recovery phase I In the case of the distribution of fuel in the tank of a motor vehicle to the distribution station, the liquid fuel supply flushes out of this tank, the gaseous phase loaded with hydrocarbons contained in the tank of the vehicle.
- This gaseous phase is then emitted into the atmosphere while, in the storage tank, the volume of liquid fuel thus subtracted is compensated by an air intake coming from the outside, generally through the vent pipe.
- phase II recovery To avoid this gas phase emission containing hydrocarbons in the surrounding atmosphere, a complementary regulation called “phase II recovery” has been introduced in some countries. For this, it implements, in the fuel dispensing gun, a collection line by suction of the gas phase of the automobile tank with a return to a storage tank of light products, generally E95.
- the volume of the sucked gas phase is identical to the volume of liquid delivered into the tank, which is not necessarily the case in practice.
- Water vapor is thus brought from outside by the vent pipe for pressure compensation or rebalancing in the storage tanks or by return to the tank of the gaseous phase sucked into the tanks of the cars. even in contact with the outside air and therefore loaded with moisture.
- This moisture has the disadvantage of causing corrosion of the walls of the tank which, in time, can be pierced with the spillage of fuel in the basement resulting in significant pollution.
- this moisture can cause icing of the water during negative temperature with a risk of clogging the vent ducts or fuel distribution ducts.
- the negative cold supply thus makes it possible to condense the hydrocarbons in a temperature range below 0 ° C. (typically 0 ° C. to -40 ° C.).
- This technique has the disadvantage of also condensing in frost water vapor contained in the gas head of the tank, which has the effect of reducing the condensation performance of gaseous hydrocarbons and impose a systematic defrosting step.
