Hereinafter, embodiments of the present invention will be described in more detail based on the drawings.
FIG. 1 is a system configuration diagram for implementing a method of proposing a recommended catalyst for an RF device according to this embodiment. The method of proposing a recommended catalyst for an RF device according to the present embodiment acquires the performance of the user's RF device, planned operating conditions, etc., and sends a catalyst suitable for the planned operating conditions to the terminal as a recommended catalyst. offer.

As shown in FIG. 1, the system has a main server 20 (device) and a data server 30 . The main server 20 and the data server 30 are communicably connected. The main server 20 and the data server 30 may be integrated or separated.

The main server 20 is connected via a network 40 to a terminal 10 operated by a user. The terminal 10 and the main server 20 may be connected by a dedicated line, or may be connected by an Internet line. The terminal 10 has a display device integrally or separately. A terminal is an information processing device owned by a user, such as a computer, a tablet terminal, or a mobile phone. Also, the terminal may be an information processing device that is not owned by the user. For example, it may be an information processing device logged in by a user. The information processing device has a processor, a storage unit for storing computer readable instructions, and a display device.

The main server 20 may be composed of a single server, or may be composed of a plurality of servers. The main server 20 consists of a processor 21 and a storage unit 22 that stores computer readable instructions. The processor 21 retrieves the computer readable instructions stored in the storage unit 22 and performs a method of suggesting recommended catalysts for RF devices, which is described in detail below.

The data server 30 is composed of a recording device such as a hard disk. The data server 30 has a bench plant database (hereinafter referred to as bench plant DB) 31 and a user database (hereinafter referred to as user DB) 32 . The bench plant DB 31 has reference performance information. The user DB 32 has user IDs and passwords registered by users, user record information, and the like. Each piece of information recorded in the user DB 32 and the bench plant DB 31 will be explained later.

FIG. 2 is a flowchart of the method according to this embodiment.
As shown in FIG. 2, the main server 20 performs user login processing (step S01). The main server 20 causes the terminal 10 to display a screen prompting the user to enter a user ID and password. The terminal 10 transmits the user ID and password entered by the user to the main server 20 . The main server 20 acquires this user ID and password. The main server 20 determines whether or not the acquired user ID and password match the user ID and password registered in the user DB 32 . If the two match, the main server 20 determines that a specific user has logged in, and proceeds with subsequent processing.

After completing the login process, the main server 20 determines whether or not there is user record information in the user DB 32 (step S02). The main server 20 inquires whether or not the user DB 32 has the user record information of the logged-in user.

If the user has previously registered user record information in the user DB 32, or if a user who has already used this method has logged into the main server 20, the user record information is recorded in the user DB 32. It is The main server 20 inquires whether or not there is user performance information in the user DB 32, and when the main server 20 determines that there is user performance information in the user DB 32 (step S02: Yes), the main server 20 selects the user from the user DB 32. (step S03).

On the other hand, there may be cases where the user DB 32 does not have user record information, such as in the case of a new user. When the main server 20 determines that there is no user performance information in the user DB 32 (step S02: No), the main server 20 causes the terminal 10 to display a screen prompting the input of user performance information. The terminal 10 transmits the user record information input by the user to the main server 20 . The main server 20 acquires the transmitted user record information (step S04) and writes it to the user DB 32. FIG.

Subsequently, the main server 20 reads the reference performance information from the bench plant DB 31 (step S05). The main server 20 calculates the user operation function by correcting the reference operation function based on the comparison between the reference performance information and the user performance information (step S06).

Performance information is information such as whether a product with a certain composition was obtained when a certain RF apparatus was operated under certain operating conditions. The performance information in the user's RF device is called user performance information, and the performance information in the bench plant is called reference performance information. A bench plant is an RF apparatus that has a proven track record of evaluating or operating various catalysts, and includes, for example, a research evaluation plant. Various information obtained when this bench plant is operated under various operating conditions is the reference performance information.

FIG. 3 shows an example of user record information. As shown in FIG. 3, the performance information includes at least information about the operating conditions and the composition of the products obtained under the operating conditions. Performance information includes at least the type of catalyst, number of days of operation, operating temperature on the first day of operation (start temperature), operating temperature on the last day of operation (final temperature), operating pressure, hydrogen oil ratio, liquid hourly space velocity of raw oil. , including operating conditions such as In addition, the performance information includes the properties of the feed oil such as the composition, density, and distillation properties of the product obtained under the operating conditions.

(driving function)
Information on products with specific compositions under specific operating conditions (catalyst type, operating temperature, operating days, operating pressure, hydrogen oil ratio, liquid hourly space velocity) based on the vast amount of actual information obtained from bench plants. can be grasped statistically. A reference operating function can be derived from the relationship between such bench plant operating conditions and product composition. In other words, the reference operating function is a function that expresses the relationship between operating conditions and the composition of products obtained when a bench plant RF unit is operated under the operating conditions.

For example, when feedstock oil with a certain composition α is supplied to a bench plant RF unit with a certain catalyst, operating temperature, operating days, operating pressure, hydrogen oil ratio, and liquid hourly space velocity, a product with a certain composition A is obtained. do. In addition, it is said that a product of a certain composition B was obtained when a feedstock oil of a certain composition β was supplied to a bench plant RF unit with a certain catalyst, operating temperature, operating days, operating pressure, hydrogen oil ratio, and liquid hourly space velocity. do. The relationship between the operating conditions such as catalyst type, operating temperature, operating days, operating pressure, hydrogen oil ratio, liquid hourly space velocity, properties of feed oil, and the composition of the product is the reference operating function. A huge amount of data is accumulated in the bench plant DB 31 regarding the relationship between each composition of the product according to the type of catalyst, operating temperature, operating days, operating pressure, hydrogen oil ratio, liquid hourly space velocity, and properties of feed oil. It is
Therefore, by inputting the type of catalyst, operating temperature, operating days, operating pressure, hydrogen oil ratio, liquid hourly space velocity, and feed oil properties, the composition of the product obtained at the bench plant can be easily calculated using the standard operating function. can be predicted to

However, since the user's RF equipment differs from the bench plant in terms of its size, shape, pipe length, etc., even if the standard operating function obtained in the bench plant is used as it is, the The composition of the resulting product cannot be accurately predicted. However, the relationship between operating conditions such as catalyst type, operating temperature, operating days, operating pressure, hydrogen oil ratio, liquid hourly space velocity, and properties of feed oil in the user's RF equipment and the composition of the product is different from those in the bench plant. There is a certain degree of correlation.

Therefore, the present inventor corrected the reference operating function obtained from the bench plant for the user's RF device to calculate the user operating function, and by using this user operating function, the generation obtained by the user's RF device We have found that the composition of matter can be easily predicted.

In addition, by using the operating function, it is possible to obtain the desired chemical composition of the catalyst from the operating conditions such as the type of catalyst, operating pressure, hydrogen oil ratio, liquid hourly space velocity, and properties of feed oil. An operating temperature that promotes the reaction can be calculated. In addition, since deterioration of the catalyst progresses as the number of operating days elapses, it is necessary to continue operation while setting the operating temperature high in order to promote desired chemical reactions in the deteriorated catalyst. Although the degree of deterioration of the catalyst changes depending on the operating temperature, the type of catalyst, etc., the degree of deterioration can also be calculated by using the operating function.

In addition, for each operation day, the properties of the product obtained from the operating conditions such as the operating temperature, the type of the specified catalyst, the operating pressure, the hydrogen oil ratio, the liquid hourly space velocity, and the properties of the raw oil are calculated, and these are calculated for the specified number of operating days. Repeatedly, it is possible to calculate the properties of the total product for a given number of operating days. The product properties shown in FIG. 6, etc. refer to the total product properties in this predetermined number of operating days.

Moreover, as the number of operating days increases, the operating temperature must be set higher so as to compensate for the activity of the deteriorated catalyst. Using the operating function, it is possible to estimate the operating temperature that will be reached at the end of the operation (final temperature). Further, when the operating temperature exceeds the upper limit temperature set for the RF device, the RF device cannot be operated substantially. Therefore, in this specification, such a situation is expressed as the end of the life of the catalyst. Using the run function, it is possible to estimate the number of days of operation (catalyst life) to reach the upper temperature limit set for the user's RF device.

In this way, by using the operating function, parameters such as operating temperature, operating days, service life, product properties, etc. can be evaluated with a small computational load. Therefore, for example, it is possible to easily calculate various parameters when an RF device is operated with a plurality of catalysts. Therefore, various parameters are calculated for a plurality of catalysts, and which catalyst has the longest life under the planned conditions set by the user, or which product has the highest economic value under the planned conditions set by the user is obtained. What is the catalyst, etc. can be evaluated.
The apparatus and method of the present embodiment are intended to suggest catalysts suitable for user's predetermined conditions by evaluating catalysts in this manner.

(Method of correcting operation function)
For example, under the same operating conditions, the octane number of the product obtained on the user's RF unit may be 80% of the octane number obtained on the bench plant's RF unit. In this case, the user operating function is obtained by correcting the reference operating function so that the octane number of the product obtained with the user's RF apparatus under the operating conditions is 80% of the octane number of the product obtained with the RF apparatus of the bench plant. obtain.
Alternatively, the composition of the product obtained in the RF device of the bench plant operates the user's RF device at an operating pressure set 10% higher than the operating pressure set in the RF device of the bench plant while other operating conditions are the same. It may be similar to the composition of the product obtained when In this case, the user operation function is obtained by correcting the reference operation function so that 1.1 times the operation pressure input by the user is used for the calculation as the operation pressure.
However, this is a simplified model, and in practice various corrections will be made depending on the operating conditions of the user's RF equipment and the composition of the product.

After calculating the user operation function as described above, the main server 20 stores the calculated user operation function in the user DB 32 .

Next, the main server 20 acquires schedule conditions and constraint conditions from the terminal 10 (step S07). FIG. 4 shows the schedule conditions and constraint conditions entered by the user. The scheduled conditions are various conditions that the user intends to set when operating his/her own RF device. Constraints are constraints on the RF device that are set when the user operates his/her RF device.
In the present embodiment, either one of the scheduled number of days of operation and the final temperature is the scheduled condition. Further, when the scheduled number of days of operation is obtained as a schedule condition, the maximum temperature of the user's RF device is obtained as a constraint, and when the final temperature is obtained as a schedule condition, the prescribed number of days of operation of the user's RF device is set as a constraint. get.

When a user wishes to evaluate multiple catalysts, there are two approaches.
The first approach is to first calculate what the operating temperature (final temperature) will be when an RF device filled with a specific catalyst is operated up to the number of days of operation specified for the RF device. method. If the ultimate temperature is lower than the upper limit temperature specified for the RF device, the catalyst is considered acceptable.
The second approach is to first calculate how many days (life) it will take for the operating temperature of an RF device filled with a specific catalyst to reach the upper limit temperature. The catalyst is considered acceptable if it has a life longer than the specified number of days of operation specified for the RF device.
Based on this idea, in the apparatus and method according to the present embodiment, either one of the scheduled number of days of operation and the final temperature is set as a scheduled condition, and when the scheduled number of days of operation is acquired as the scheduled condition, the user The upper limit temperature of the RF device is set as a constraint condition, and the specified operating days of the user's RF device are set as a constraint condition when the final temperature is obtained as a scheduled condition. For example, in the first approach, a specified number of operation days is set as a scheduled condition, and an upper limit temperature is set as a constraint condition. In the second approach, the final temperature is set as the scheduled condition, and the specified operating days are set as the constraint condition.

In the RF apparatus, the catalyst is periodically subjected to regeneration treatment to recover the activity of the catalyst and reused. The timing of this reproduction is set for each user's RF device. At the timing of this regeneration, the RF device must be stopped. In other words, there is a limit to the number of days that the RF device can continue to operate. For this reason, the user sets the number of days of operation to within the number of days for which operation can be continued. The number of days of operation set by the user is called a specified number of days of operation.

In general, it is often attempted to operate the RF device under conditions partially changed from past operating conditions. For example, it is often the case that only the operating pressure is changed and the other conditions are kept as they were in the past (operating conditions entered in the performance information). Therefore, in the present embodiment, the operating conditions that are changed by the user are referred to as scheduled conditions, and the operating conditions that are diverted from the operating conditions input in the performance information are referred to as diversion conditions.

A case where the user evaluates the catalyst based on the first approach will be described with reference to FIGS. 2 and 4 to 6. FIG. FIG. 4 shows schedule conditions, constraint conditions, and diversion conditions input by the user. As shown in FIG. 2, the main server 20 acquires the scheduled conditions, the diversion conditions, and the constraint conditions from the terminal 10 or the data server 30 (step S07).

In the example shown in FIG. 4, the main server 20 acquires the scheduled operating days and operating pressure as the scheduled conditions. Also, the main server 20 acquires the upper limit temperature as a constraint. Further, the main server 20 obtains the target octane number, the hydrogen oil ratio, the liquid hourly space velocity, and the properties of the raw material oil by using the user record information registered in the user database 32 . The main server 20 also acquires catalyst types A, B, and C that the user wants to compare.

Based on the diversion conditions, the scheduled conditions, and the user operation function, the main server 20 determines either the planned number of days of operation or the final temperature reached when the user's RF device is operated under the scheduled conditions and the diversion conditions for a plurality of catalyst types. The other is calculated (step S08).
In this example, the main server 20 calculates the final temperatures of the catalysts A, B, and C when the user's RF device is operated under the predetermined conditions and the diversion conditions, based on the diversion conditions, the scheduled conditions, and the user operation function. calculate. FIG. 5 is a graph showing the relationship between operating days and operating temperature obtained from the user operating function.

As described above, by using the operating function, it is possible to obtain a product with a desired composition from the operating conditions such as the type of catalyst, operating pressure, hydrogen oil ratio, liquid hourly space velocity, and feed oil properties. An operating temperature can be calculated that promotes the desired chemical reaction. The operating temperature at which the undegraded catalyst promotes the desired chemical reaction on the first day of operation is called the initiation temperature. This onset temperature is the Y-intercept in FIG.
Also, by using the operating function, the degree of deterioration of the catalyst can be calculated from the operating temperature, the type of catalyst, and the like. The degree of deterioration is shown as the slope of the graph in FIG.

That is, the Y intercept and slope in FIG. 5 can be calculated from the acquired scheduled conditions, the diversion conditions, and the user operation function, and straight lines A, B, and C can be calculated from these. The straight lines A, B, and C themselves show changes in operating temperature according to operating days when the user's RF apparatus is operated under predetermined conditions using catalysts A, B, and C, respectively. That is, the straight lines A, B, and C should be set when trying to obtain a product having a target octane number under the operating conditions set as the predetermined conditions and the diversion conditions using the catalysts A, B, and C, respectively. It shows the operating temperature depending on the day. Further, the operating temperature at the intersection of the straight lines A, B and C and the specified number of operating days is the final temperature reached when each of the catalysts A, B and C is used.
Note that the graph shown in FIG. 5 is shown for convenience of explanation, and the main server 20 may be configured to display it on the terminal 10, or may be configured not to display it.

Next, the main server 20 outputs to the terminal 10 at least one catalyst whose calculated final temperature satisfies the constraint (step S09). FIG. 6 shows an example of evaluation results displayed on the screen of the terminal 10 by the main server 20. As shown in FIG.

In FIG. 5, the final temperature reached by the catalyst A is below the upper limit temperature, which is a constraint condition. The final temperature reached by catalyst B is below the upper limit temperature, which is a constraint condition. The ultimate temperature reached by the catalyst C exceeds the upper limit temperature, which is a constraint condition. That is, catalysts A and B satisfy the constraint, and catalyst C does not. Therefore, the main server 20 outputs to the terminal 10 that at least the catalysts A and B are recommended catalysts that satisfy the constraint. Therefore, unlike FIG. 6, the main server 20 may display on the display section of the terminal 10 only that catalysts A and B are recommended catalysts.

However, the device 1 can provide various useful information to the terminal 10 of the user by calculation using the driving function. Therefore, with reference to FIG. 6, items that are preferably output to the terminal 10 together with the recommended catalyst will be described.

In FIG. 6, the main server 20 displays the final temperature reached for each evaluated catalyst. By knowing the final temperature, the user can know the margin of the final temperature with respect to the upper temperature limit of the user's RF device.

In FIG. 6, the ultimate temperatures of the catalysts A and B are lower than the upper limit temperature, so the catalysts A and B are judged to be suitable for the user's RF device, and are circled in the life column. Since the ultimate temperature of catalyst C exceeds the upper limit temperature, catalyst C is judged to be unsuitable for the user's RF device, and the service life is marked with x. In this way, the user can easily understand at a glance by displaying with ◯ and × depending on whether or not the constraint is satisfied.

In FIG. 6, the main server 20 displays life ranks. This life rank is determined in descending order of temperatures obtained by subtracting the ultimate temperature from the upper limit temperature. When the user wants to evaluate the catalyst by the final temperature reached with respect to the upper limit temperature, it can be evaluated at a glance by this life rank. That is, the main server 20 compares the final temperature reached with the upper limit temperature, and expresses the degree of approximation between them by the difference between the final reached temperature and the upper limit temperature. The catalyst may be displayed together with this degree of approximation. The degree of approximation may be expressed by the ratio of both, instead of the difference between the two.

In FIG. 6, the main server 20 displays the product composition obtained when using each catalyst. For users looking to particular ingredients, it is preferable to have the composition of the product displayed. In addition, the user can examine the catalyst by comprehensively judging the composition of the product and the service life of the catalyst. As described above, using the user operation function, the properties of the product obtained from the operating conditions such as the operating temperature, the type of the specified catalyst, the operating pressure, the hydrogen oil ratio, the liquid hourly space velocity, and the properties of the raw oil are calculated for each operating day. can be calculated. The main server 20 repeats the calculation of the properties of the products for a predetermined number of operating days, and calculates the total properties of the products in the predetermined operating days shown in FIG.

In FIG. 6, the main server 20 displays economic ranks. Using the operating function, the composition of the products obtained with each catalyst can be calculated. Therefore, by multiplying the production amount of each component by the economic value of each component and adding them up, the economic value of the product can be calculated. Also, the total merit can be calculated by subtracting the cost of the catalyst consumed at this time from the economic value of the product. The main server 20 may be configured to assign an economic rank in descending order of total merit. When the user wants to evaluate the catalyst from an economic point of view, the user can evaluate the catalyst at a glance based on this economic rank.
The economic value of the product may be calculated from the yield of any one of the reformed gasoline, mixed xylene and hydrogen. Among the components of the product, these three are particularly useful components.

Next, the case where the user evaluates the catalyst using the second approach described above will be described. That is, it is a method of calculating how many days (lifetime) it will take for the operating temperature of the user's RF device to reach the upper limit temperature.

2 and 7 to 9, the case where the user evaluates the catalyst based on the second approach will be described. FIG. 7 shows schedule conditions, constraint conditions, and diversion conditions input by the user. As shown in FIG. 2, the main server 20 acquires the scheduled conditions, the diversion conditions, and the constraint conditions from the terminal 10 or the data server 30 (step S07).

In the example shown in FIG. 7, the main server 20 acquires the final temperature and the operating pressure as the scheduled conditions. In addition, the main server 20 acquires the specified operating days as a constraint. Further, the main server 20 obtains the target octane number, the hydrogen oil ratio, the liquid hourly space velocity, and the properties of the raw material oil by using the user record information registered in the user database 32 . The main server 20 also acquires catalyst types D, E, and F that the user wants to compare.

The main server 20 calculates the number of days of scheduled operation for the catalysts D, E, and F when the user's RF device is operated under the scheduled conditions and the diversion conditions, based on the diversion conditions, the scheduled conditions, and the user operation function (step S08). ). FIG. 8 is a graph showing the relationship between operating days and operating temperature obtained from the user operating function.

As shown in FIG. 8, when catalysts D and E were used, the planned number of days of operation until reaching the final temperature set as the planned condition was longer than the specified number of days of operation. When catalyst F was used, the planned number of days of operation until reaching the final temperature set as the planned condition was smaller than the prescribed number of days of operation. In other words, catalysts D and E are the catalysts whose scheduled number of days of operation satisfies the constraint.

FIG. 9 shows an example of an evaluation result displayed on the terminal 10 by the main server 20. As shown in FIG. As shown in FIG. 9, the main server 20 outputs to the terminal 10 that at least catalysts D and E are recommended catalysts that satisfy the constraint. In FIG. 9 as well, catalysts D, E, and F were evaluated using the same evaluation items as those shown in FIG. 6, and the results are displayed.

In the above-described first and second examples, the example in which the main server 20 acquires the operating pressure as a scheduled condition in addition to either the scheduled number of days of operation or the final temperature reached has been described. However, the present invention is not limited to this.
When the device of the present embodiment evaluates the catalyst, the predetermined conditions or diversion conditions are either one of the number of operation days and the final temperature, the operating pressure, the hydrogen oil ratio, the liquid hourly space velocity, and the feedstock oil. It can be calculated by obtaining the properties and the target octane number of the product. In other words, all of the operating pressure, the hydrogen oil ratio, the liquid hourly space velocity, the properties of the raw oil, and the target octane number of the product may be set as predetermined conditions, or at least one of these items may be set. It may be set as a scheduled condition.

When using direct simulation, it is necessary to execute direct simulation each time the type of catalyst is changed or the operating pressure is changed. It was impractical to evaluate multiple types of catalysts under conditions.
According to the apparatus and method according to the present embodiment, the processing load can be reduced and the operating temperature, the number of operating days, and the composition of the product can be accurately predicted as compared with direct simulation. Therefore, it is easy to evaluate these with a plurality of catalysts, and based on this evaluation, it is possible to propose a catalyst suitable for the user's predetermined conditions.

In the embodiment described above, the main server 20 is configured to acquire the type of catalyst to be compared when acquiring the scheduled conditions, but the present invention is not limited to this. The main server 20 may be configured to evaluate all catalysts registered with the data server 30 . Alternatively, the configuration may be such that multiple types of catalysts close to the catalyst designated by the user are selected and the selected catalyst is evaluated.

Although the embodiments of the present invention have been described above, it goes without saying that the technical scope of the present invention should not be limitedly interpreted by the description of the embodiments. It should be understood by those skilled in the art that this embodiment is merely an example, and that various modifications of the embodiment are possible within the scope of the invention described in the claims. The technical scope of the present invention should be determined based on the scope of the invention described in the claims and their equivalents.
