[0008] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a diagram showing the configuration of a cost calculation system 1 according to this embodiment. The cost calculation system 1 includes an adhesion prevention system 2 and a calculation device 3. In the cost calculation system 1, the adhesion prevention system 2 prevents adhesion of dirt on a target facility, and the calculation device 3 calculates the cost for the adhesion prevention system 2 preventing the adhesion of dirt.

[0009] 2 is a diagram showing an example of the configuration of the adhesion prevention system 2. The adhesion prevention system 2 includes a target facility 21, an adhesion prevention device 22, and a sensor 23. The target equipment 21 is a device for which adhesion of dirt is to be suppressed. The target equipment 21 is, for example, a heat exchanger or a pipe. The target equipment 21 is, for example, a device for manufacturing a product. The products manufactured by the target equipment 21 are, for example, crude oil, petroleum, chemical raw materials, chemical products, and food and beverages.

[0010] The adhesion prevention device 22 is a device that prevents adhesion of dirt to the target equipment 21. The adhesion prevention device 22 outputs data on the operation of preventing adhesion of dirt to the calculation device 3. The adhesion suppression device 22 is, for example, an ultrasonic generator, and suppresses adhesion of dirt by generating ultrasonic waves in the target equipment 21. The adhesion suppression device 22 outputs, for example, data on the generated ultrasonic waves to the calculation device 3. The suppression of adhesion of dirt to the target equipment 21 may be performed using a scale inhibitor. Means for suppressing adhesion of dirt to the target equipment 21, such as the adhesion suppression device 22 and the scale inhibitor, will be referred to as adhesion suppression means hereinafter.

[0011] The sensor 23 is attached to the target equipment 21. The sensor 23 measures process data representing state quantities (temperature, flow rate, etc.) of the target equipment 21. The state quantities of the target equipment 21 are used as judgment indication values ​​for estimating the degree of adhesion of dirt to the target equipment 21. For example, when the target equipment 21 is a heat exchanger, the sensor 23 measures the flow rate of fluid flowing into the low-temperature fluid side of the heat exchanger and the temperature of the fluid at each of the inlet and outlet. Also, for example, when the target equipment 21 is a heat exchanger, the sensor 23 measures the flow rate of fluid flowing into the high-temperature fluid side of the heat exchanger and the temperature of the fluid at each of the inlet and outlet.

[0012] 3 is a diagram showing an example of the configuration of the calculation device 3. The calculation device 3 includes a sensor data acquisition unit 31, a suppression effect identification unit 32, a compensation calculation unit 33, a billing cost calculation unit 34, an output unit 35, and a storage unit 39. The storage unit 39 stores process data acquired by the sensor data acquisition unit 31 and constants used by the compensation calculation unit 33 to calculate the compensation.

[0013] The sensor data acquiring unit 31 acquires process data that represents a state quantity related to the target equipment 21, which is sensor data measured by the sensor 23.

[0014] The suppression effect specifying unit 32 specifies an effect (hereinafter, referred to as suppression effect) obtained as a result of the adhesion of dirt being suppressed by the adhesion suppression means. The suppression effect specifying unit 32 specifies the suppression effect, for example, by comparing past process data with current process data. The past process data is stored in the storage unit 39, for example.

[0015] The storage unit 39 may store the correspondence relationship between the time information and the suppression effect, and the suppression effect identification unit 32 may identify the suppression effect based on the correspondence relationship between the time information and the suppression effect. The time information is, for example, information about a season or a month. Since the suppression effect may differ depending on the environmental conditions, it is possible to eliminate the influence of environmental factors, which are external factors, by identifying the suppression effect based on the correspondence relationship between the time information and the suppression effect.

[0016] The compensation calculation unit 33 calculates compensation for suppression based on the suppression effect identified by the suppression effect identification unit 32 and the measurement results by the sensor 23. The compensation calculated by the compensation calculation unit 33 increases, for example, as the suppression effect increases. For example, there are several stages of suppression effect, with a high suppression effect corresponding to a high compensation and a low suppression effect corresponding to a low compensation.

[0017] The billing cost calculation unit 34 calculates the billing cost based on the consideration calculated by the consideration calculation unit 33. The billing cost calculation unit 34 calculates a higher billing cost when the consideration exceeds a predetermined standard than when the consideration does not exceed the predetermined standard.

[0018] The billing cost calculation unit 34 may calculate different billing costs depending on the payment method of the billing cost. The payment method is, for example, a subscription method in which payment is made periodically over a predetermined period of time, or an incentive method in which payment is made only when the improvement effect exceeds a predetermined standard. The billing cost calculation unit 34 may calculate different billing costs when the payment method of the billing cost is different between the subscription method and the incentive method, while the compensation is the same.

[0019] There may be multiple types of suppression effects. The types of suppression effects may differ depending on the products manufactured by the target equipment 21.

[0020] The suppression effect is, for example, the effect of reducing cleaning-related costs for cleaning dirt on the target equipment 21. When calculating the suppression effect based on the cleaning-related cost reduction effect, the compensation calculation unit 33 calculates the suppression effect based on the number of objects to be cleaned included in the target equipment 21, the number of cleanings in a predetermined period, and the size of the target equipment 21.

[0021] 4 is a diagram showing the reduction effect of a series of cleaning-related costs, such as the direct cleaning cost, the cost of preparation for performing the cleaning work, and the cost of treating waste liquid after cleaning. The compensation calculation unit 33 calculates the product of the number of target equipment 21, the number of cleanings reduced per year by introducing the service, and the cleaning-related costs, which differ depending on the size of the target equipment 21, as the reduction cost. The compensation calculation unit 33 calculates the reduction cost as compensation. Cleaning-related costs, which vary with the size of the target equipment 21, may also vary with the product that the target equipment 21 produces.

[0022] The suppression effect is, for example, an effect of improving the operation rate by not performing the previous cleaning. When calculating the compensation for suppression based on the operation rate improvement effect, the compensation calculation unit 33 calculates the compensation for suppression based on the time previously required to clean the target equipment 21 in a specified period, the operation time of the target equipment 21 in the specified period, and the production volume of the target equipment 21. In the case of conventional cleaning methods (physical cleaning and chemical cleaning), it is necessary to stop the target equipment 21, but the adhesion suppression means allows the target equipment 21 to continue operating without stopping it.

[0023] Fig. 5 is a diagram showing the effect of improved operation rate. The compensation calculation unit 33 calculates the improved operation rate by calculating the ratio of the reduced cleaning time (time spent on cleaning) to the equipment operation time. Thereafter, the compensation calculation unit 33 calculates a predicted increase in sales by multiplying the production volume by the improved operation rate, and calculates the expected increase in income (expected income increase) by multiplying the predicted increase in sales by the profit margin. The compensation calculation unit 33 calculates the expected income increase as compensation.

[0024] The suppression effect is, for example, the effect of reducing energy required to compensate for the deterioration of performance of the target equipment 21 due to the adhesion of dirt to the target equipment 21. When calculating the consideration for suppression based on the effect of reducing the required energy, the consideration calculation unit 33 calculates the consideration for suppression based on the required heat exchange amount and the decrease in thermal efficiency of the target equipment 21 in a predetermined period. The decrease in thermal efficiency is calculated, for example, from the difference between the measurement results of temperature and flow rate by the sensor 23. When calculating the consideration for suppression based on the improvement effect of the required energy, the consideration calculation unit 33 calculates the consideration for suppression based on the decrease in thermal efficiency due to the adhesion of dirt to the target equipment 21, the unit price of a heat source such as steam, and the operating time of the target equipment 21.

[0025] FIG. 6 is a diagram showing an example of the effect of reducing energy required to compensate for the deterioration of the performance of the target equipment 21 due to the adhesion of dirt. The compensation calculation unit 33 calculates the steam consumption (e.g., annual steam consumption) in a predetermined period from the steam consumption per hour of the target equipment and the equipment operation time. The compensation calculation unit 33 may estimate the steam consumption based on the pipe diameter, steam pressure, and steam flow rate. The compensation calculation unit 33 multiplies the steam consumption in the predetermined period by the value of the thermal efficiency decrease due to the adhesion of dirt to the target equipment 21 to calculate the amount of steam required for compensation (required compensation steam amount). The compensation calculation unit 33 calculates the cost required for compensation by multiplying the required compensation steam amount by the steam unit price. The steam unit price is calculated by calculating the amount of energy required to produce steam per unit, calculating the amount of fuel required to produce the amount of energy with a specified fuel (such as city gas) from the lower heating value (heat amount per unit volume), and setting the unit price of the fuel amount and the specified fuel as the steam unit price. The compensation calculation unit 33 calculates the cost required for compensation as compensation. The steam pressure may be measured by the sensor 23. The consideration calculation unit 33 may estimate the steam consumption based on the steam flow rate [t / h] measured by the sensor 23.

[0026] The suppression effect is, for example, the effect of reducing the carbon dioxide emission carbon price or carbon dioxide related tax that increases by producing compensatory steam required to maintain the heat amount when dirt adheres to the target equipment 21. When calculating the suppression consideration based on the reduction effect of the carbon dioxide emission carbon price or carbon dioxide related tax, the compensation calculation unit 33 calculates the suppression consideration based on the type of fuel used in the target equipment 21, the amount of energy equivalent to the usage amount of the compensatory heat source in a specified period, the carbon dioxide emission coefficient corresponding to the type of fuel, and the carbon dioxide trading price or global warming countermeasures tax.

[0027] FIG. 7 is a diagram showing an example of the reduction effect of the carbon dioxide emission carbon price or carbon dioxide related tax. The compensation calculation unit 33 calculates the amount of carbon dioxide generation that can be reduced by reducing the use of surplus energy through cleaning by multiplying the carbon dioxide emission coefficient corresponding to the type of fuel by the amount of energy (compensatory fuel amount) equivalent to the amount of use of the compensation heat source in a specified period. The compensation calculation unit 33 calculates the carbon dioxide trading cost by multiplying the amount of carbon dioxide generation by the carbon dioxide trading price or the sum of ICP (Internal carbon pricing) and global warming countermeasures tax as the global warming countermeasures tax. The compensation calculation unit 33 calculates the carbon dioxide trading cost as the compensation.

[0028] The suppression effect is, for example, an effect of improving the productivity decline of the target equipment 21 caused by the adhesion of dirt to the target equipment 21. When calculating the consideration for suppression based on the effect of improving the productivity decline, the consideration calculation unit 33 calculates the consideration for suppressing the dirt of the target equipment 21 based on the profit brought about by the target equipment 21 in a predetermined period and a numerical value corresponding to the productivity decline. The numerical value corresponding to the productivity decline is calculated based on, for example, the difference in flow rate measured by the sensor 23.

[0029] Fig. 8 is a diagram showing an example of an improvement effect of productivity decline. The compensation calculation unit 33 calculates the profit brought by the target equipment 21 in a predetermined period by multiplying the production volume and the profit rate. The compensation calculation unit 33 uses the productivity decline rate in the case where the target equipment 21 is not cleaned as a numerical value corresponding to the productivity decline, and calculates the opportunity profit loss by multiplying the productivity decline rate by the profit brought by the target equipment 21. The compensation calculation unit 33 calculates the opportunity profit loss as compensation.

[0030] The suppression effect is, for example, an effect of improving equipment damage caused by adhesion of dirt to the target equipment 21. Equipment damage is, for example, corrosion or thinning caused by cleaning.

[0031] The suppression effect includes, for example, an effect of improving the environmental load caused by suppressing adhesion of dirt to the target equipment 21. When calculating the compensation for suppression based on the effect of improving the environmental load, the compensation calculation unit 33 calculates the environmental load when chemical cleaning is performed instead of using ultrasonic waves or a scale inhibitor as the compensation. The compensation calculated here is, for example, the cost required for neutralizing and disposing of chemical waste liquid generated when chemical cleaning is performed.

[0032] The suppression effect includes an improvement effect of a decrease in yield caused by, for example, dirt adhering to the target equipment 21 and the dirt peeling off and mixing into the product. Fig. 9 is a diagram showing the improvement effect of a decrease in product yield. The compensation calculation unit 33 calculates the compensation for cleaning by multiplying the production volume, the waste loss rate caused by dirt mixing into the product, and the cost rate of the product.

[0033] The output unit 35 outputs the compensation information calculated by the compensation calculation unit 33. The output unit 35 includes, for example, a display unit, and displays a plurality of figures corresponding to each of the suppression effects. The size of each of the displayed figures corresponds to the size of the compensation indicated by the corresponding suppression effect. FIG. 10 is an example of a plurality of figures corresponding to each of the suppression effects displayed on the display unit. The plurality of figures corresponding to each of the suppression effects are, for example, pie charts. The display unit may display the compensation indicated by the suppression effect or a ratio to the total compensation together with the plurality of figures corresponding to each of the suppression effects. The output unit 35 may output the billed cost calculated by the billed cost calculation unit 34.

[0034] 11 is a flowchart showing the operation of the calculation device 3. The sensor data acquisition unit 31 acquires sensor data from the sensor 23 (step S101). The suppression effect identification unit 32 identifies the suppression effect based on the sensor data (step S102). The compensation calculation unit 33 calculates the compensation (step S103). The output unit 35 outputs the calculated compensation (step S104).

[0035] FIG. 12 is a diagram showing an example of the configuration of the calculation device 3 according to the second embodiment. The calculation device 3 according to the second embodiment includes a maintenance timing estimation unit 36 ​​in addition to the calculation device 3 according to the first embodiment. A storage unit 39 according to the second embodiment stores a maintenance timing estimation model. The maintenance timing estimation model is a model that receives a measurement result by the sensor 23 as an input and outputs the maintenance timing of the target equipment 21. The maintenance timing estimation model is obtained by machine learning that uses the measurement result by the sensor 23 (for example, the difference between the temperatures measured by the sensor 23 and the temperatures at the inlet and outlet of the heat exchanger) as learning data and uses the maintenance timing of the target equipment 21 (for example, the maintenance timing when the adhesion of dirt to the target equipment 21 is suppressed by the adhesion suppression device 22) as a correct answer corresponding to the learning data.

[0036] The maintenance timing estimation unit 36 ​​estimates the maintenance timing by inputting the measurement results by the sensor 23 into the maintenance timing estimation model. This makes it possible to grasp the maintenance timing.
