Correction is made based on the properties calculated in advance and the analyzed values of the analyzed properties, and the properties of the gasoline base material stored in the base material tank 230 are recognized. Specifically, the calculation result calculated based on the property estimation formula stored in the storage unit 310 described above is recognized as the property of the gasoline base material.

[Operation of gasoline preparation system]
Next, a gasoline preparation operation will be described as an operation of the gasoline preparation system 100 shown in FIG. 1 described above. FIG. 3 is a flowchart showing an operation of preparing a base material with a predetermined property at the time of gasoline preparation.

First, the preparation control device 300 recognizes the properties of each base material fraction measured by the fraction property measuring means 215 and flowing through each branch pipe 211 of the transport line 210 by the fraction property recognizing means 321 of the calculating means 320, for example, Density of substrate fraction (D _i ), vapor pressure (RVP _i ), research octane number (RON _i ), motor method octane number (MON _i ), distillation properties (initial boiling point, 10% point, 30% point, 50 The fraction property information of% point, 70% point, 90% point, end point) is acquired (step S101). The preparation control apparatus 300 recognizes the inflow amount of each base material fraction measured by the flow meter 217 and flowing through each branch pipe 211 of the transfer line 210 by the fraction flow rate recognition unit 322 of the calculation unit 320, that is, each base unit. Fraction flow rate information relating to the flow rate of the material fraction is acquired (step S102).

  Then, the computing means 320 computes the properties of the gasoline base material based on the properties and flow rates of each base material fraction by using the respective property estimation formulas stored in the storage means 310 by the base material characteristic recognizing means 323. (Step S103). The property of the gasoline base material recognized in step S103 is compared with the base material target value information set in advance and stored in the storage means 310, and it is determined whether or not the property is a predetermined property (step S104). If it is determined in step S104 that the predetermined property is obtained, the property of the gasoline base material calculated by the property estimation formula is recognized as the property of the gasoline base material stored in the base material tank 230 and stored in the storage means 310. Output and store appropriately (step S105). On the other hand, if it is determined in step S104 that the predetermined properties are not obtained, the distillate flow rate control means 324 controls each regulating valve 216 to appropriately change the flow rate, and the process returns to step S102. That is, the process which adjusts a flow volume suitably in the state by which the property of a gasoline base material becomes a predetermined property.

  Thereafter, the calculation means 320 determines whether or not there is a stop request such as interruption or cancellation of the gasoline preparation process (step S106). When recognizing that a stop request has been made, the calculation means 320 performs a process of interrupting or canceling the gasoline preparation process. On the other hand, if it is recognized in step S106 that there is no stop request, the process returns to step S101 and the process of specifying the properties of the gasoline base material is continued. Thus, by repeatedly calculating the properties of the gasoline base material, the properties of the prepared gasoline base material are continuously monitored. Then, the preparation control device 300 controls the blending device 250 based on the properties of the gasoline base material recognized by the above-described processing and the product target value information, and appropriately adjusts the flow rate of the gasoline base material to obtain a predetermined value. Process to prepare gasoline base material with properties.

[Operation effect of gasoline preparation system]

Recognize the amount of base material fraction that flows into the base material tank 230 and the gasoline base material that is prepared by the base material fraction flowing into the base material tank 230. Based on the properties of the pseudo sample prepared in this way, the properties of the gasoline base material prepared by flowing the base material fraction into the base material tank 230 is recognized by the base material characteristic recognition means 323. For this reason, it is not necessary to directly measure the properties of the gasoline base material, the properties of the gasoline base material for producing the gasoline can be sequentially recognized, the gasoline can be continuously produced, and the gasoline can be produced efficiently. Furthermore, the configuration and work for measuring the properties of the gasoline base material are not required, and the configuration can be simplified and made more efficient. In addition, it is possible to identify the properties of the gasoline base material with high accuracy and accuracy without measuring the properties of the gasoline base material, and to easily recognize the properties of the gasoline base material by performing the operation of separately preparing the pseudo sample. .

  Further, the base material characteristic recognition unit 323 determines the gasoline base material based on the properties of each base material fraction recognized by the fraction property recognition unit 321 and the inflow amount of each base material fraction recognized by the fraction flow rate recognition unit 322.

The property of the base material is recognized, that is, the property of the gasoline base material is recognized using the property estimation formula. For this reason, it is possible to specify the properties of the gasoline base material successively and accurately without the need to measure the gasoline base material, and it is easy to identify the properties of the gasoline base material quickly and efficiently by calculating the simple property estimation formula. Therefore, an efficient gasoline preparation can be easily obtained, and a control configuration for preparing the gasoline can be easily simplified.

  Further, the characteristics of the gasoline base material, which recognizes each inflow amount that the base material fraction adjusted by the regulating valve 216 flows into the base material tank 230 by the distillate flow rate control means 324, is necessary for producing gasoline. The amount of inflow is controlled so as to correspond to the properties of the gasoline base material. For this reason, the gasoline base material prepared by inflow of the base material fraction can be immediately used for the production of gasoline that is appropriately mixed based on the recognized properties of the gasoline base material, and can efficiently produce gasoline, Control is easy and gasoline can be manufactured easily.

  Moreover, the mixer 220 which mixes each base material fraction is provided in the conveyance line 210 which flows in each base material fraction into a base material tank.

Furthermore, by using a static mixer as the mixer 220, a gasoline base material can be efficiently prepared in a short time with a simple configuration, and a power source is unnecessary, so that the preparation cost can be easily reduced. In addition, by providing a structure in which the branch pipe 211 through which each base material fraction flows is mixed in the main pipe 212 connected to one pipe, the base material fraction is mixed to some extent when it joins in the main pipe 212. In addition, the efficiency of in-tube mixing is further improved, and a simplified apparatus configuration and a more efficient preparation of a gasoline base can be easily obtained with a simple structure.
