Description

  The present invention relates to an environmental impact substance emission evaluation apparatus and an environmental impact emission evaluation method.

Conventionally, deterioration of the atmospheric environment due to greenhouse gases typified by carbon dioxide (CO ₂ ) has become a serious social problem. In particular, in recent years, it has been pointed out that the rise in temperature on a global scale is the effect of greenhouse gases, which has become a serious international problem. In light of this situation, the Kyoto Protocol for the Prevention of Global Warming came into effect in February 2005, and international agreements were implemented regarding numerical targets for greenhouse gas reduction, emissions trading, joint implementation, clean development mechanisms, etc. . However, it is considered extremely difficult to achieve the numerical targets for greenhouse gas reduction due to economic growth and growth in electricity demand.

  On the other hand, since the consumer cannot grasp the environmental impact of the energy source required for the power generation of the power supplied to the consumer, the consumer simply uses energy that has been saved through energy saving in order to reduce the environmental load. The only way to reduce the amount was to take concrete measures for environmental conservation.

  In such a situation, a power supply method is disclosed in which a power consumer is made to select a power with a small environmental load and a supply state for each power plant is planned according to the demand of the consumer (for example, a patent). Reference 1). Also, for automobiles, etc., fuel brands sold to automobiles, such as fuel brands, additives, date of sale, etc., are sent to the automobiles, and the amount of greenhouse gases corresponding to the amount of fuel consumed by the automobiles is evaluated. The technique to do is disclosed (for example, refer patent document 2).

JP 2001-184406 A JP 2007-064091 A

  However, the technique described in Patent Document 1 is a technique that takes into account electric power that is required to be immediately adjusted for supply. For example, a fuel that is primarily stored in a fuel supply station such as a gas station. Is not taken into account. Furthermore, when considering the environmental nature of energy in a strict sense, not only the energy is considered by the form of power generation, but also the environmental nature accumulated in the process of mining primary energy, transportation / storage, fuel production and supply. It is necessary to think. For example, when power is generated using hydrogen as a fuel, the environmental characteristics of hydrogen obtained by converting natural energy into electricity and further hydrolyzing water and hydrogen obtained by reforming petroleum differ greatly.

In addition, regarding the automobile fuel in the technology described in Patent Document 2, the amount of CO ₂ emitted when a certain amount of fuel is burned by the brand is almost constant, and the amount of CO ₂ emitted by the vehicle can be calculated. Become. However, for example, when biofuel is mixed, it is conceivable that the CO ₂ emission amount varies greatly depending on the origin of the biofuel and the manufacturing process. In addition, it is difficult to specify the CO ₂ emission amount when the fuel mining location is different even with the same brand of automobile fuel.

  The present invention has been made in view of such a background, and the present invention quantifies the amount of environmental impact emissions in each process of manufacturing, transporting and using raw fuel, and displays the amount of emissions. An object of the present invention is to provide an environmental impact emission evaluation apparatus and an environmental impact emission evaluation method that support reduction of environmental impact emissions by energy suppliers and energy consumers.

  In order to solve the above-described problem, the environmental impact emission evaluation apparatus acquires identification information from the tags provided in the raw material tank, the utility supply apparatus, and the product tank, and determines the target process. The environmental impact emission evaluation device acquires flow rate data from the flow rate measuring means provided in each pipe connected to the raw material tank, the utility supply device, and the product tank, and the storage unit of the environmental impact emission assessment device The amount of environmental impact substance emission in the process is calculated and displayed using the heat quantity per unit quantity and the data on the amount of environmental impact substance emission per unit quantity of heat stored in.

  According to the present invention, in each process of manufacturing and transporting raw fuel, the amount of environmental impacts emitted by energy suppliers and energy consumers is quantified and displayed by quantifying the amount of environmental impact emissions. It is possible to provide an environmental impact emission evaluation device and an environmental impact emission evaluation method that support reduction.

  Next, the process information processing unit 120 (see FIG. 2) of the environmental impact substance emission evaluation device 1 stores the storage unit based on the raw material tank ID and the product tank ID acquired by the raw fuel facility information acquisition unit 110. The tank master table 520 (see FIG. 4) in 500 is searched to determine whether or not the tank ID is registered (step S1202). If the tank ID is not registered (step S1202 → No), a screen prompting the tank ID registration is output under the control of the display control unit 150, and the process is terminated. On the other hand, when the tank ID is registered (step S1202 → Yes), the process proceeds to step S1203.

The process information processing unit 120 receives the raw fuel for each tank in the tank accounting table 580 (see FIG. 10) in the storage unit 500 when the measurement information acquisition unit 130 (see FIG. 2) acquires the flow rate data. A new record relating to the delivery amount and the received amount is created (step S1205).

And the measurement information acquisition part 130 acquires flow volume data for every predetermined time from the flow volume measurement means 40 (refer FIG. 1) installed in each piping etc. (step S1206), the tank accounting table 580, and the process data table 560. (See FIG. 8).

Then, the environmental evaluation processing unit 140 associates the environmental impact emission amount calculated in step S1207 and the environmental impact emission basic unit calculated in step S1208 with the process data ID, and processes in the storage unit 500. It memorize | stores in the evaluation table 570 (refer FIG. 9) (step S1210). In addition, the environmental evaluation processing unit 140 refers to the process connection tank table 550 (see FIG. 7), and when the takeover flag of the process is “1”, the environmental impact emission amount of the product manufactured by this process is reduced. The unit is registered as the raw fuel in the raw fuel table 510 (see FIG. 3).
The environmental evaluation processing unit 140 may calculate the efficiency of the process using the above-described (Equation 4), and may store the calculated process efficiency in the process evaluation table 570 in step S1210.

  Subsequently, the display control unit 150 of the environmental impact material discharge amount evaluation apparatus 1 displays the environmental impact material discharge amount, the environmental impact material discharge basic unit, and the like stored in the process evaluation table 570 for each process. The information is displayed on a liquid crystal display or the like (step S1211).

FIG. 16 is a diagram illustrating an example of a supply chain table 600 according to the second embodiment. The supply chain table 600 stores a product delivery side tank ID and a reception side tank ID in association with the raw fuel ID. By recording tank IDs for delivering and receiving raw fuel in the supply chain table 600, it becomes possible to manage the distribution channels of products.

  In the energy transportation means 70 according to the second embodiment, a plurality of products transported from different raw material tanks 10 may be mixed and stored in one product tank 30. In the case of mixing such environmental impact substances and a plurality of products having different discharge amounts, the environmental impact discharge amount evaluation apparatus 1b according to the second embodiment uses the supply chain table 600 and the tank accounting shown in FIG. Using the table 580 (see FIG. 10) and the tank state table 590 (see FIG. 11), the mixed products in the same tank can be managed individually.

For example, the case where an ethanol tank and a gasoline tank are connected via piping or transportation means and ethanol is transferred to the gasoline tank will be described.
When ethanol is transferred to the gasoline tank, in the supply chain table 600, as shown by ID “2” in FIG. 16, the raw fuel ID “2” of ethanol and the delivery tank ID “2” (ethanol tank) are received. Data with a tank ID of “3” (gasoline tank) is input, and the ethanol distribution channel is stored.

  Then, the amount of ethanol delivered is measured by the flow rate measuring means 40M (see FIG. 13) provided in the raw material tank. Then, as illustrated in the ID “3” of the tank accounting table 580 shown in FIG. 10, the ethanol tank ID “2”, the delivery raw fuel name “ethanol”, the delivery amount “8” (L), the date and time Is memorized. Next, the amount of ethanol received into the product tank 30 is measured by the flow rate measuring means 40P provided in the product tank. Then, the gasoline tank ID “3”, the received raw fuel name “ethanol”, the received amount “8” (L), and the date and time are stored in the ID “4” of the tank accounting table 580. In this way, the input / output of the raw fuel for each tank is managed.

  Further, the tank state table 590 is updated from the state of the tank state table 590 shown in FIG. 11 to the current storage amount state of each tank as shown in FIG. Therefore, “8” (L) is subtracted from the stored amount of the ethanol tank of ID “2”, and the stored amount becomes “92” (L). Then, a record with a new ID “4” is created, and ethanol of the raw fuel ID “2” is stored as “8” (L) in the tank ID “3” of the gasoline tank. As a result, in the gasoline tank with the tank ID “3”, the gasoline with the raw fuel ID “3” indicated by the ID “3” contains the stored amount “1000” (L) and the raw fuel ID “ID” indicated by the ID “4”. It is managed that ethanol of “2” exists at a ratio of the storage amount “8” (L), and a total of 1008 (L) is stored.

  By doing in this way, even if the product contained in the tank is composed of a plurality of fuels, the environmental impact material emission evaluation device 1b considers the composition ratio of each fuel and the environmental impact. It becomes possible to calculate the amount of discharge.

  As described above, also in the process of transporting raw fuel, the amount of environmental impact emission and the amount of environmental impact emission are the same as those in Embodiment 1 using the fuel impact emission evaluation apparatus 1b according to the second embodiment. The basic unit can be calculated and displayed.
