Method of blending fuels and related system
View Patent ↗A method and related system blend fuels and dispense a blended fuel to a vehicle at a fueling station. In one aspect, the method comprises selecting the desired proportion of at least one of the fuels available at the service station, blending that fuel with another one available, and delivering the blended fuel to the vehicle. Preferably, the first fuel is a non-renewable, petroleum based one, while the second fuel is a non-petroleum based, renewable one (such as ethanol or biodiesel).
1. A method of encouraging resource conservation at a fueling station for dispensing a blended fuel to a vehicle, comprising:
substantially matching a temperature of a renewable biodiesel fuel and a non-renewable diesel fuel prior to blending;
blending the renewable biodiesel fuel and the non-renewable diesel fuel at the fueling station to produce the blended fuel; and
obtaining an incentive based on the amount of the renewable biodiesel fuel in the blended fuel.
2. The method of claim 1 , further comprising selecting the amount of at least one of the renewable and non-renewable fuel comprising the blended fuel.
3. The method of claim 1 , further comprising the step of pricing the blended fuel according to the incentive obtained.
4. The method of claim 3 , further comprising displaying the amount of savings realized by the consumer by selecting a particular blended fuel.
5. A system for dispensing blended biodiesel fuels at a fueling station having a first storage vessel having a first biodiesel fuel at the fueling station and a second storage vessel having a second petroleum-based diesel fuel at the fueling station, comprising:
a fuel terminal with a nozzle adjacent the storage vessels;
a selector for selecting a proportion of at least one of the first or second fuels to be blended with the other to create a blended biodiesel fuel for delivery through the nozzle;
a heat exchanger for substantially matching a temperature of the first fuel to the second fuel prior to blending; and
a blender for blending the first biodiesel fuel with the second petroleum-based diesel fuel at the selected proportion and at the substantially matched temperature to form a blended fuel having a desired B factor delivered through the nozzle.
6. The system of claim 5 , wherein the blender includes a flow control valve associated with each storage tank and a common line for receiving the flow of each fuel from the corresponding storage vessel.
7. The system of claim 5 , wherein the blender comprises at least one metering pump.
8. The system of claim 5 , further including a common delivery line associated with the nozzle and the blender.
9. The system of claim 5 , wherein the common delivery line includes a mixer.
10. The system of claim 5 , further including a third storage vessel having a third fuel and a fourth storage vessel having a fourth fuel, and further including a second selector for selecting a proportion of the third fuel to the fourth fuel to be blended by a second blender for delivery through the nozzle.
