For example, fuel oil for internal combustion engines such as light oil, kerosene, naphtha, A heavy oil, C heavy oil, etc. Any form of mixed fuel oil in which alcohol is mixed with can be targeted. Moreover, although the structure which supplies to vehicles, such as a motor vehicle, as a fuel oil supply body in what is called a gas station which is a gas station, alcohol and fuel oil are mixed and it supplies to a fuel oil supply body as mixed fuel oil. The fuel oil supply body is not limited to a vehicle such as an automobile, but can be any supply target such as an airplane, a ship, or a storage tank. Can do.
FIG. 1 is a conceptual diagram showing a schematic configuration of a fuel oil supply apparatus according to a first embodiment of the present invention.

In FIG. 1, reference numeral 100 denotes a fuel oil supply device. The fuel oil supply device 100 is provided, for example, in a gas station 10 that is a filling station, and alcohol is mixed in a vehicle 1 such as an automobile as a fuel oil supply body. This is a facility for appropriately supplying mixed fuel oil, which is gasoline.
Here, as the mixed fuel oil, for example, gasoline and ethyl tertiary butyl ether (ETBE) as an ether mixed with ethanol, which is an alcohol derived from a raw material, are appropriately mixed, for example, 60 Examples of those mixed at a ratio of / 40 to 95/5. And as ETBE, it produces | generates by reaction of what is called bioethanol which is ethanol derived from biomass produced | generated from industrial wastes, such as a plant and garbage, for example, and isobutene produced | generated as a by-product of petroleum products.

And in the gas station 10, the fuel oil storage tank 11 as a fuel oil storage part is installed under the ground. The fuel oil storage tank 11 is capable of flowing mixed fuel oil conveyed from an oil refinery, which is a manufacturing apparatus for producing mixed fuel oil, through a tank lorry or the like from an inlet (not shown) and flowing out the mixed fuel oil that has flowed in. To accumulate.
Further, the gasoline station 10 is provided with a fuel oil supply unit 12 as a supply path for appropriately pumping the mixed fuel oil stored in the fuel oil storage tank 11 from the fuel oil storage tank 11 and supplying the mixed fuel oil to the vehicle 1.
The fuel oil supply unit 12 is connected to the fuel oil storage tank 11 and displays a flow pipe 12A as a flow path provided with a pump (not shown), for example, a supply amount to be supplied and a charge that is a price for the supplied mixed fuel oil. A counting unit 12B having a display device (not shown) and the like, a supply nozzle 12C for supplying the mixed fuel oil to the vehicle 1, and the like are provided.

An oil / water separator 15 is provided in the flow pipe 12 </ b> A of the fuel oil supply unit 12 of the gasoline station 10. The oil / water separator 15 separates and removes water mixed from the mixed fuel oil flowing through the flow pipe 12A. Examples of the oil / water separator 15 include a filter separator and a so-called coalescer, and various configurations that can separate and remove water by any method such as adsorption or filtration can be applied. In addition, it is desirable to have a configuration that can separate and remove not only water mixed in a colloidal form but also dissolved water. And the fuel oil supply apparatus of this invention is comprised by 12 A of distribution pipes and oil-water separation apparatus 15 which comprise this supply path | route.
