Description

The present invention relates to devices, methods, programs and non-temporary computer-readable recording media that propose recommended catalysts for use in FCC devices.

A fluid catalytic cracking apparatus (hereinafter referred to as an FCC apparatus) for obtaining highly economical products such as light hydrocarbons from low-grade heavy raw material oil by fluid catalytic cracking is known.

Japanese Patent Application Laid-Open No. 2003-58206

This FCC device has various restrictions on the device depending on the maximum amount of the extraction pump for each distillate and the like.
For example, it is assumed that the maximum extraction amount of the pump for extracting fractions A and B is 100 [barrel / day (hereinafter referred to as B / D)]. At this time, if the flow rate of the distillate A is already 100 [B / D] and the flow rate of the distillate B is 80 [B / D], the flow rate of the distillate A cannot be increased any more. , It is not possible to operate to increase the supply of raw material oil. However, the constraint condition for fraction B has not been reached yet, and there is room for increased production from the viewpoint of device utilization. As described above, the present inventor has noticed that in order to fully bring out the performance of the FCC device, it is necessary to consider the influence on the ancillary equipment of the FCC device.
Therefore, the present inventor has focused on the fact that there is room to bring out the performance of the FCC apparatus by changing the catalyst. For example, when the flow rate of the distillate A is 100 [B / D] and the flow rate of the distillate B is 80 [B / D] when the catalyst α is used, the supply amount of the feedstock oil is increased. However, the flow rate of the distillate A cannot be increased any more. However, when the catalyst β is used, there is a possibility that the flow rate of the distillate A can be set to 95 [B / D] and the flow rate of the distillate B can be set to 90 [B / D]. When the fractions A and B have the same economic value, economic merits can be expected when the catalyst β is used as compared with the case where the catalyst α is used.
However, depending on the replacement of the catalyst, for example, the flow rate of the fraction A may exceed 100 [B / D], and in such a case, the operation under the same conditions cannot be performed. Thus, for the purpose of obtaining economic benefits, it is difficult to predict fluctuations in the amount of product produced due to catalyst replacement, and in particular, the risk of exceeding the constraints is high, so catalyst replacement Cannot be done easily.

By the way, Patent Document 1 and the like have proposed a direct simulation of an FCC device. Since such a direct simulation precisely simulates the shape of the FCC device and the reaction model of each fraction, a huge amount of input data and a large amount of calculation are required. Therefore, it is not realistic to use direct simulation in replacing various catalysts and calculating the economic merits obtained by the catalysts one by one.

Therefore, the present invention provides an apparatus, a method and a program capable of proposing a catalyst suitable for a user's purpose in an FCC apparatus without using a direct simulation.

In order to achieve the above object, the present invention provides the following.

It is a figure which shows an example of a planned operation condition. This is an example of a screen to be displayed on the terminal.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a system configuration diagram of a method of providing a product of the FCC apparatus according to the present embodiment to a terminal. The device (hereinafter, simply referred to as device 1) obtains the actual results of the user's FCC device, the planned operating conditions, and the like, and determines the obtained rate of the product of the FCC device according to the present embodiment, and the planned operating conditions. Provides to the terminal the yield of the product obtained when the user's FCC device is operated in.

As shown in FIG. 1, the device 1 has a main server 20 and a data server 30. The main server 20 and the data server 30 are communicably connected to each other. The main server 20 and the data server 30 may have an integrated configuration or a separate configuration.

The device 1 is connected to a terminal 10 (terminal) operated by the user via the network 40. 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. The terminal is an information processing device such as a computer, a tablet terminal, or a mobile phone owned by the user. Further, 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 includes a processor, a storage unit for storing computer-readable instructions, and a display device.

The main server 20 may be configured by a single server or may be configured by a plurality of servers. The main server 20 includes a processor 21 and a storage unit 22 that stores computer-readable instructions. The processor 21 reads a computer-readable instruction stored in the storage unit 22 and executes a method of providing the terminal with the profitability of the product of the FCC apparatus 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 a bench plant DB) 31 and a user database (hereinafter referred to as a user DB) 32. The bench plant DB 31 has standard actual information. The user DB 32 has a user ID and password registered by the user, user record information, and constraint conditions. Each information recorded in the user DB 32 and the bench plant DB 31 will be described later.

FIG. 2 is a flowchart of the method according to the present embodiment.
As shown in FIG. 2, the main server 20 executes a user login process (step S01). The main server 20 causes the terminal 10 to display a screen prompting the user ID and password to be input. 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 they match, the main server 20 determines that a specific user is logged in and proceeds with the subsequent processing.

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

If the user has registered the user record information in the user DB 32 in advance, or if the user who has already used this method is logged in to the main server 20, the user record information is recorded in the user DB 32. Has been done. When the main server 20 inquires whether or not the user record information is in the user DB 32 and the main server 20 determines that the user DB 32 has the user record information (step S02: Yes), the main server 20 is from the user DB 32 to the user. Read the user record information of.

On the other hand, there may be a case where the user DB 32 does not have the user record information, such as in the case of a new user. When the main server 20 determines that the user DB 32 does not have the user record information (step S02: No), the main server 20 causes the terminal 10 to display a screen prompting the input of the user record 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 in the user DB 32.

Subsequently, the main server 20 reads out the reference actual information from the bench plant DB 31 (step S05). The main server 20 corrects the profit rate balance calculation function based on the comparison between the reference actual result information and the user actual result information (step S06).

The actual information is information such as what kind of profit rate the product was obtained when a certain FCC device was operated under what operating conditions. The actual information in the FCC device of the user is called the user actual information, and the actual information in the bench plant is called the standard actual information. The bench plant is an FCC device having a track record of evaluating or operating various catalysts, and examples thereof include an evaluation plant for research. Various information obtained when this bench plant is operated under various operating conditions is the standard actual information.

FIG. 3 shows an example of user performance information. As shown in FIG. 3, the performance information includes at least information on operating conditions and the yield of the resulting product. The performance information includes at least the flow rate of the feedstock, the properties of the feedstock, the type of catalyst, and the product yield balance.
The operating conditions included in the performance information are the supply flow rate of the feedstock oil to the FCC device, the density of the feedstock oil, the residual carbon concentration of the feedstock oil (hereinafter also referred to as the residual carbon concentration), the type of catalyst, and the feedstock with multiple feedstock oils. If it is composed of, the ratio, the density of each raw material, the residual carbon concentration, etc. are included. Further, as information on the yield of the obtained product (product yield balance) included in the actual information, the density of each product obtained and the amount of each product obtained are included.

(Profit rate balance calculation function)
Based on the vast amount of performance information obtained from the bench plant, it is possible to statistically understand that products can be obtained with a predetermined product yield balance from the types of raw material oils and catalysts with specific flow rates and properties. can. A yield balance calculation function can be derived from the relationship between the properties of the feedstock oil of such a bench plant, the supply flow rate of the feedstock oil, the type of catalyst, and the yield of the obtained product. In other words, the yield balance calculation function is a function that expresses the relationship between the operating conditions such as the feedstock oil, the flow rate, the properties, and the catalyst type, and the yield of the product obtained by the FCC apparatus.

For example, it is assumed that when the raw material oil having a certain composition α is supplied to the bench plant by the flow rate Q1 and the catalyst A, the flow rates a1, b1 and c1 are obtained for the product fractions A, B and C, respectively. Further, when the raw material oil having a certain fraction composition β was supplied to the FCC apparatus of the bench plant by the flow rate Q2 and the catalyst B, the flow rates a2, b2 and C2 were obtained for the fractions A, B and C of the product, respectively. do. The relationship between the production amount of each product according to the properties of the raw material oil, the flow rate, and the catalyst is the yield balance calculation function. A huge amount of data is accumulated in the bench plant DB 31 regarding the relationship between the properties of the raw material oil, the flow rate, and the amount of each product produced according to the catalyst.
Therefore, if the properties, flow rate, and catalyst of the feedstock oil are input, the amount of each product obtained in the bench plant can be easily predicted by using the yield balance calculation function.

However, since the size, shape, length of piping, etc. of the user's FCC device are different from those of the bench plant, the user's FCC device can be used as it is even if the profit rate balance calculation function obtained in the bench plant is used as it is. It is not possible to accurately predict the yield of the product obtained in. However, the relationship between the flow rate and properties of the feedstock oil in the user's FCC device and the product yield balance of the product has a certain degree of correlation with those in the bench plant.

Therefore, the present inventor corrects the yield balance calculation function obtained from the bench plant for the user's FCC device, and obtains the product obtained by the user's FCC device from the flow rate and properties of the feedstock oil. I found that I could easily predict.

(Specific method of correction of profit rate balance calculation function)
For example, if the total production of each product of the user's FCC device with respect to the flow rate of the feedstock is 100 times the total production in the bench plant, the total production of the products will be 100 times as a whole. Correct the profit rate balance calculation function. Further, when the fraction of the product of the user's FCC apparatus consists of three fractions A, B, and C, the flow rates of the product to the fractions A, B, and C in the bench plant are 100 times and 95, respectively. If it is double or 103 times, the profit rate balance calculation function is corrected so that the profit rate is corresponding to it. However, the simplified model is described here, and in reality, various corrections are made according to the operating conditions of the user's FCC device.

After correcting the profit rate balance calculation function as described above, the main server 20 stores the corrected function in the user DB 32 as a user profit rate balance calculation function.

Returning to FIG. 2, the main server 20 then acquires the constraint condition of the user's FCC device (step S07). The constraint condition of the FCC device is, for example, the maximum withdrawal flow rate of the pump for acquiring each product shown in FIG. When the feedstock oil is passed through the catalyst, fractions such as Dry gas, C3 and C4 are generated from the feedstock oil. The FCC device is provided with a pump for taking out these fractions for each fraction.

For example, user A may be less interested in C3 and user B may be more interested in C3. In this case, the maximum withdrawal flow rate of the C3 pump of the user A may be lower than the maximum withdrawal flow rate of the pump of the C3 of the user B. As described above, the maximum withdrawal flow rate of the pump of each distillate may be different for each user.
For example, even if the amount of C3 produced is theoretically expected to be 0.70 [10,000 kL / 30 days], the maximum withdrawal flow rate of the C3 pump of User A's FCC device is 0.50 [10,000 kL / 30 days]. In the case of [day], the amount of C3 produced in the FCC device of the device of user A is 0.50 [10,000 kL / 30 days]. On the other hand, when the maximum withdrawal flow rate of the pump of C3 of the FCC device of the user B is 1.00 [10,000 kL / 30 days], the amount of C3 produced by the FCC device of the user B is 0.70 [10,000 kL / 30 days]. 30 days]. Further, even if the amount of C3 produced is lower than the maximum withdrawal flow rate of the pump, the relationship between the amount of each product produced and the maximum withdrawal flow rate of the pump may be affected. In this way, the upper limit of each distillate of the FCC device is determined for each user. The main server 20 acquires this upper limit value as a constraint condition for each fraction.

The main server 20 determines whether or not the user DB 32 has a constraint condition (step S07). If the user DB 32 has a constraint condition (step S07: Yes), the main server 20 acquires the constraint condition from the user DB 32 (step S08). If there is no constraint condition in the user DB 32 (step S07: No), the main server 20 acquires the constraint condition from the terminal 10 (step S09). The main server 20 causes the terminal 10 to display a display prompting the input of the constraint condition. The terminal 10 transmits the input constraint condition to the main server 20. The main server 20 acquires the constraint conditions transmitted from the terminal 10.

Next, the main server 20 acquires the scheduled operation conditions from the terminal 10 (step S10). Scheduled operation conditions are various conditions that the user intends to set when operating his / her own FCC device. For example, when the user wants to change the raw material oil, he / she inputs information including the supply flow rate of the raw material oil to be changed and its properties as the scheduled operation condition. Alternatively, the user is currently using a catalyst called "BASE", but if he wants to know what kind of product yield can be obtained by using the catalyst "A", the user can use the type of catalyst as a planned operation condition. Enter the information including "A" as the scheduled operation condition.

FIG. 5 shows an example of scheduled operation conditions. As shown in FIG. 5, the planned operating conditions include at least the flow rate of the feedstock and the density of the feedstock. In addition to this, the planned operating conditions may include the residual carbon concentration of the raw material oil (in the case of processing a plurality of raw materials, the residual carbon concentration of each raw material oil), the type of catalyst, and the like. Although FIG. 5 shows an example of displaying in volume display, it may be displayed in weight display. Further, the unit of quantity used in each of the above-mentioned calculations may be handled by volume or by weight.

Returning to FIG. 2, the main server 20 acquires the scheduled operation condition, the constraint condition, and the user profitability balance calculation function as described above. The main server 20 calculates the amount of each product obtained when the user's FCC device is operated under the scheduled operation conditions and the constraint conditions by applying the scheduled operation conditions and the constraint conditions to the user profit rate balance calculation function. do. Further, the main server 20 calculates the amount of each product produced for a plurality of types of catalysts including at least a catalyst input as a scheduled operation condition (hereinafter, simply referred to as a scheduled catalyst) (step S11).

For a plurality of types of catalysts, a catalyst having properties similar to those of the planned catalyst may be selected, or any catalyst may be selected regardless of the planned catalyst. Alternatively, a plurality of types of catalysts that the user is considering to adopt may be acquired, and these catalysts may be used to calculate the amount of each product produced.

The main server 20 then evaluates the usefulness of the products obtained with each type of catalyst based on the weighting factor of the usefulness of each product. For example, usefulness is economic value, and the weighting factor in this case is unit price. FIG. 6 is a screen to be displayed on the terminal 10 in step S13 described later. FIG. 6 shows the products obtained with each type of catalyst and the economic value of each product.
For example, after calculating the amount of product produced for each type of catalyst as shown in FIG. 6, the main server 20 multiplies the amount of each product produced by a unit price to calculate the economic value per unit time. .. The sum of the economic values per unit time for each product is the economic value (usefulness) per unit time of the product.
Alternatively, if the user A wants to produce a large amount of C3 in particular, instead of simply doubling the unit price, the unit price of C3 is doubled, for example, to calculate the usefulness of the product.

After calculating the usefulness of the product for each type of catalyst in this way, the main server 20 identifies the catalyst from which the most useful product can be obtained (step S12). In the example shown in FIG. 6, the economic value (treatment merit) of the product obtained when the catalyst B is used is the highest. Therefore, the main server 20 identifies the catalyst B as a catalyst for obtaining the most useful product, and notifies the terminal 10 of information including at least the identified catalyst (step S13).

The main server 20 transmits the display shown in FIG. 6 to the terminal 10 and displays it on the screen of the terminal 10. In the screen shown in FIG. 6, the catalyst B is highlighted to inform the user that the catalyst B is the most useful catalyst. Further, the main server 20 not only simply displays the most useful catalyst, but also, as shown in FIG. 6, the amount of each product produced when each catalyst BASE, A, B is used. , Their prices, processing merits, etc. may be displayed on the terminal 10.

As described above, the apparatus and method for providing the product acquisition rate of the FCC apparatus according to the present embodiment can quickly provide the product acquisition rate to the user by a simple calculation method without relying on direct simulation. As a result, the yield of the product according to the catalyst can be easily predicted, so that the catalyst that can obtain the product having the desired yield can be notified to the user.

In the calculation result shown in FIG. 6, an example in which the unit price of each product was used as the weighting coefficient was described. In this case, the main server 20 acquires the unit price stored in the data server 30 from the data server 30 before executing step 11. On the other hand, if the user wants to set his or her own weighting factor, such as maximizing the production of a specific product or maximizing the total amount of two specific products, the main server steps 11 Prior to this, the step of obtaining a weighting factor for the usefulness of each product from the user may be performed.

Further, as shown in FIG. 6, the main server 20 provides the terminal with the usefulness of the product obtained for each of a plurality of types of catalysts calculated based on the planned operating conditions scheduled by the user and the constraint conditions of the user plant. , May be displayed in comparison with the usefulness of the product in the user performance information. In FIG. 6, the usefulness of the product in the user performance information is the data in which the catalyst type is shown in the BASE column, and a plurality of types of catalysts calculated based on the planned operating conditions planned by the user and the constraint conditions of the user plant. The usefulness of the product obtained for each is the data shown in the columns of catalysts A and B.

At this time, the main server 20 determines the unit price of each product and the amount of each product produced for each of the plurality of types of catalysts calculated based on the planned operating conditions planned by the user and the constraint conditions of the user plant. Calculate the total price of each product based on. In addition, the total price of each product is calculated based on the unit price of each product and the amount of each product produced in the user performance information. The main server 20 compares and displays both on the terminal. This allows the user to see for himself the usefulness of the products obtained in the past and the usefulness of the products obtained with various types of catalysts.
In the display shown in FIG. 6, the case where the catalyst A is used in <A>-<BASE> and the case where the planned operation condition (catalyst BASE) is used are compared, and the catalyst B is used in <B>-<BASE>. The case where there is a case and the case where the planned operation condition (catalyst BASE) is used are compared.

Further, as shown in FIG. 6, the cost of the catalyst consumed under each operating condition may be subtracted from each total price, and the subtraction results may be compared and displayed on the terminal. For example, the main server 20 may evaluate the value obtained by subtracting the catalyst cost required for producing the product from the processing merit as [economic efficiency in consideration of the catalyst cost]. Regarding this [economic efficiency considering the catalyst cost], the catalyst B is the most useful, so the main server 20 transmits the catalyst B to the terminal 10 in step S13.

In the above-described embodiment, the maximum withdrawal flow rate of each distillate pump is illustrated as a constraint condition, but the constraint condition is not limited to this. The constraint condition is at least one of the conditions outside the FCC device specifications and the accompanying operable range, such as the maximum removal flow rate of the extraction pump for each distillate of the product and the maximum amount of air supplied to the regeneration tower of the catalyst. Is.

It is understood by those skilled in the art that the present embodiment is merely an example, and various embodiments can be modified within the scope of the invention described in the claims.
