Is calculated, and by comparing the obtained property measurement value and the predetermined control value, the temperature, the pressure, and the like are automatically adjusted by the purification control means 31 so that the temperature, the pressure, and the like become the predetermined target values. The efficiency of the property control can be improved. Further, the base material tank 17 is provided with a base material flow rate measuring device 32 so that the blend ratio of the gasoline base material in the initial stage of blending is calculated based on data obtained by the property measuring means 33 and the like. Therefore, an accurate initial blend ratio can be determined.

なっているという虞れはなくなる。Further, since the data obtained by the product property measuring device 35 is inputted to the blend control means 36 and the result is fed back to the flow rate regulator 34 of each gasoline base material, the blend ratio is automatically adjusted. Even if the properties of each gasoline base material fluctuate during production, the properties of the product can be kept at a constant target value. In addition, since the distillation property value is measured not only at one point as in the related art but at many points as described above, an accurate blend ratio can be obtained. Therefore, unlike the conventional case, since the blending ratio of each gasoline base material is constant during the blending process, there is no fear that the properties of the obtained product are different due to the property fluctuation of the gasoline base material during production.

As compared with the case in which at least one gasoline base material and at least one product receiving tank are required, the number of tanks can be considerably reduced by, for example, 30 to 70% in the entire manufacturing apparatus. As a result, the equipment cost can be reduced and the space used can be made more efficient. In the above embodiment, the case where the petroleum product is gasoline has been described as an example, but the present invention relates to other petroleum products,
For example, the present invention can be similarly applied to light oil, heavy oil, and the like.
