Abstract
Description
[Technical field]
[0001] The present disclosure relates to an ammonia reactor control system and a method for producing hydrogen. [Background technology]
[0002] For example, in variably operating the amount of ammonia decomposition depending on the state of a traveling vehicle using a fuel cell, if the amount of ammonia supplied is controlled to vary depending on the temperature of the cracker (e.g., reactor), the ammonia decomposition rate in the reactor due to changes in the temperature of the reactor can be stabilized.
[0003] In such a load-following operation process, if the supply of ammonia to the reactor is increased in order to increase the amount of hydrogen produced in a short period of time, a temperature drop is induced in the reactor because the temperature of the supplied ammonia is generally room temperature.
[0004] When the temperature inside the cracker temporarily drops, the ammonia decomposition rate drops, which can lead to catalyst inactivation and overall equipment performance degradation. This leads to an increase in the amount of ammonia remaining in the equipment. Residual ammonia is supplied to the absorption tower and fuel cell, which can lead to overall equipment performance degradation and unexpected failures.

[0034] FIG. 1 is a block diagram of an ammonia reactor control system according to an exemplary embodiment of the present disclosure.
[0035] Referring to Figure 1, an ammonia reactor control system 10 includes a cracker 100, an absorber 200, and a fuel cell 300. Each component / node can transmit and receive data to and from different components / nodes. The components / nodes can be connected via a network.
[0036] The ammonia reactor control system 10 according to an embodiment of the present disclosure can receive and decompose ammonia (NH3) through a cracker 100. If the temperature inside the cracker 100 temporarily drops, the ammonia decomposition rate may decrease due to catalyst inactivation or performance degradation in the cracker 100. As a result, the amount of residual ammonia in the cracker 100 may relatively increase.
[0037] According to an exemplary embodiment, the cracker 100 can receive ammonia and produce hydrogen (H2), nitrogen (N2) and ammonia (NH3) as decomposition products. Each fluid absorbed through the absorption section 200 can then be supplied to the fuel cell 300 and used to power the battery.
[0038] According to an exemplary embodiment, the fuel cell 300 can feed nitrogen and unconverted hydrogen, etc. back to the cracker 100 to completely combust the unconverted hydrogen. This allows the ammonia reactor control system 10 to feedback reburn by-products that are generated due to imbalances in the materials fed into the cracker 100.
[0039] FIG. 2 is a schematic block diagram illustrating a configuration of an ammonia reactor control system according to an exemplary embodiment of the present disclosure.
[0040] 2, the ammonia reactor control system 10 can include a cracker 100, a sensor unit 110, a control unit 120, a hydrogen supply unit 130, an ammonia supply unit 140, and a memory unit 150. The internal configuration included in the ammonia reactor control system 10 can include, but is not limited to, the absorption unit 200 and the fuel cell 300 shown in FIG.
[0041] In some embodiments, the functions of the controller 120 may be performed by another processing server or a cloud server instead of the controller 120.
[0042] According to an exemplary embodiment, the reactor of the ammonia reactor control system 10 may refer to an apparatus such as a cracker 100 .
[0043] The control unit 120 may receive ammonia supply amount information from the ammonia supply unit 140. The control unit 120 may receive hydrogen supply amount information from the hydrogen supply unit 130. According to an exemplary embodiment, the control unit 120 may receive the supply amounts of ammonia and hydrogen supplied into the cracker 100 of the ammonia reactor control system 10 from the ammonia supply unit 140 and the hydrogen supply unit 130, respectively.
[0044] The control unit 120 can receive temperature information inside the cracker 100 from the sensor unit 110. The control unit 120 can receive the internal temperature including the first and second parts of the cracker 100. The sensor unit 110 can include a plurality of sensors and collect temperature information of the first and second parts of the cracker 100. The first and second parts can refer to parts of the cracker 100 that do not overlap with each other. In some embodiments, the first and second parts can be parts of a part where the ammonia supply unit 140 and the cracker 100 are connected.
[0045] According to an exemplary embodiment, the hydrogen supply unit 130 can determine the amount of hydrogen to be supplied to the cracker 100 according to a first signal from the control unit 120. The amount of hydrogen to be supplied to the cracker 100 can be adjusted according to the first signal from the control unit 120.
[0046] According to an exemplary embodiment, the ammonia supply unit 140 can determine the amount of ammonia to be supplied to the cracker 100 according to the second signal of the control unit 120. The amount of ammonia to be supplied to the cracker 100 can be adjusted according to the second signal of the control unit 120.
[0047] According to an exemplary embodiment, the memory unit 150 may store data supporting various functions of the ammonia reactor control system 100 and a program for the operation of the control unit 120. The memory unit 150 may store input / output data (e.g., images, videos, etc.), and may store application programs (or applications) that run in the ammonia reactor control system 10, and data and commands for the operation of the ammonia reactor control system 10. At least one of the application programs may be downloaded from an external server via wireless communication.
[0048] The storage unit 150 may include at least one type of storage medium among a network attached storage (NAS), a flash memory type, a hard disk type, a solid state disk type, a silicon disk drive type, a multimedia card micro type, a card type memory (e.g., SD or XD memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. The storage unit 150 may include a database that is separate from the ammonia reactor control system 10 but is connected by wire or wirelessly.
[0049] The ammonia reactor control system 10 may further include an output unit (not shown). The output unit is for generating an output related to a visual, an auditory, or a tactile sense, and may include a display unit.
[0050] The display unit may form an interlayer structure with a touch sensor or may be provided as an integral structure with the touch sensor to realize a touch screen.

[0051] The display unit displays (outputs) information processed in the ammonia reactor control system 10. For example, the display unit can display execution screen information of an application program (e.g., an application) running in the ammonia reactor control system 10, or UI (User Interface) or GUI (Graphic User Interface) information based on the execution screen information.
[0052] At least one component may be added or removed depending on the performance of the components shown in Figure 2. Also, it will be readily understood by those of ordinary skill in the art that the relative positions of the components may be changed depending on the performance or structure of the ammonia reactor control system 10.
[0053] Each of the components shown in FIG. 2 may refer to software and / or hardware components such as field programmable gate arrays (FPGAs) and application specific integrated circuits (ASICs).
[0054] FIG. 3 is a schematic flow chart illustrating a control method for an ammonia reactor control system according to an exemplary embodiment of the present disclosure.
[0055] Referring to FIG. 3, an ammonia reactor control system (e.g., the ammonia reactor control system 10 in FIG. 1) can calculate the amount of heat absorbed in a cracker (e.g., the cracker 100 in FIG. 1) from temperature information inside the cracker, and temporarily reduce the output of the fuel cell.
[0056] In step S310, the control unit (for example, the control unit 120 in FIG. 2) can receive the ammonia supply amount information. The control unit 120 can receive the ammonia supply amount via an ammonia supply unit (for example, the ammonia supply unit 140 in FIG. 2). The control unit 120 can receive the ammonia supply amount information via another flow meter or supply amount measuring device provided in the ammonia supply unit 140.
[0057] In step S320, the control unit 120 can check the preset heat supply amount information. The ammonia reactor control system 10 can adjust the hydrogen supply pattern to be different via the first signal so as to provide an improved heating effect in consideration of the stability of the hydrogen reaction. For example, the same total amount of hydrogen can be supplied in different patterns.
[0058] The control unit 120 can check the preset heat supply amount information from the storage unit (e.g., the storage unit 150 in FIG. 2). In step S330, the control unit 120 can calculate the heat absorption amount information in the cracker 100 based on the temperature information received via the sensor unit (e.g., the sensor unit 110 in FIG. 2).
[0059] In step S340, the control unit 120 can temporarily reduce the output of the fuel cell 300 by comparing the preset heat supply amount information with the heat absorption amount information in the cracker 100. For example, the temporary time may be about 3 to 5 seconds, and may vary depending on experimental values. The preset heat supply amount information may correspond to a threshold value of the heat absorption amount in the cracker 100.
[0060] According to an exemplary embodiment, the preset heat supply amount can be set to a heat supply amount that can prevent a temperature drop in the cracker 100 due to excessive ammonia or excessive hydrogen in the cracker.
[0061] The control unit 120 can determine the first signal based on temperature information and ammonia supply amount information. The control unit 120 can control the temperature rise effect in the cracker through preset heat supply amount information using the first signal.
[0062] According to an exemplary embodiment, when the amount of heat absorbed in the cracker is lower than the preset amount of heat supply, the control unit 120 can increase the amount of hydrogen supply via the first signal to increase the temperature in the cracker 100. This can amplify the temperature increase effect in the ammonia reactor control system 10.
[0063] According to an exemplary embodiment, the control unit 120 can increase the amount of hydrogen supplied from the fuel cell 300 as the temperature of the cracker 100 decreases. This allows the control unit 120 to quickly increase the temperature of the cracker 100. In determining the amount of hydrogen to be supplied, the control unit 120 can change the hydrogen supply pattern so as to maximize the temperature increase effect while taking into account the stability of the hydrogen reaction.
[0064] FIG. 4 is a schematic flow chart illustrating ammonia preheat of an ammonia reactor control system according to an exemplary embodiment of the present disclosure.
[0065] In step S410, a control unit (e.g., control unit 120 in FIG. 2) can receive temperature information of ammonia supplied into a cracker (e.g., cracker 100 in FIG. 1). The control unit 120 can receive the temperature information of ammonia via another temperature detection unit 60 that detects the temperature of ammonia supplied into the cracker 100.
[0066] In step S420, the control unit 120 may determine a third signal based on the temperature information of the ammonia. The control unit 120 may preheat the ammonia before supplying it to the cracker via the third signal. The ammonia reactor control system (e.g., the ammonia reactor control system 10 of FIG. 1) may further include a preheating unit 50 that preheats the temperature of the ammonia supplied into the cracker 100 according to the third signal. The preheating unit 50 may be located inside or outside the ammonia supply unit (e.g., the ammonia supply unit 140). The preheating unit 50 may be located at any position that can preheat the ammonia in the ammonia supply unit 140.
[0067] According to an exemplary embodiment, the control unit 120 can receive temperature information of the ammonia in the ammonia supply unit 140 from the temperature detection unit 60. This allows the control unit 120 to check whether the temperature of the ammonia supplied to the cracker 100 via the ammonia supply unit 140 is lower than the temperature of the ammonia already present in the cracker 100.
[0068] In one embodiment, when the temperature of the ammonia in the ammonia supply unit 140 is lower than the temperature of the ammonia in the cracker 100, the control unit 120 can operate the preheating unit via the third signal to increase the temperature of the ammonia in the ammonia supply unit 140.
[0069] In one embodiment, when the temperature of the ammonia in the ammonia supply unit 140 supplied to the cracker 100 is low, the control unit 120 can operate the preheating unit to preheat the temperature of the ammonia in the ammonia supply unit 140 via the third signal.
[0070] As described above, it is possible to control the cause of the temperature drop inside the cracker 100. For example, the temperature can be controlled by utilizing the mechanism of decomposing ammonia, which is an endothermic reaction.
[0071] According to an exemplary embodiment, the preheating section may include a material having high thermal conductivity and large heat capacity. The preheating section may be formed of a material that can achieve uniform heat transfer during preheating of ammonia.
[0072] FIG. 5 is a schematic flow chart illustrating the ammonia feed rate determination of the ammonia reactor control system according to an exemplary embodiment of the present disclosure.
[0073] In step S510, the control unit (e.g., the control unit 120 in FIG. 2) can receive hydrogen supply amount information from the hydrogen supply unit (e.g., the hydrogen supply unit 130 in FIG. 2). The control unit 120 can receive the hydrogen supply amount information via another flow meter or supply amount measuring device provided in the hydrogen supply unit 130.
[0074] In step S520, the control unit 120 can determine the amount of ammonia to be supplied according to a preset temperature range. The control unit 120 can determine the amount of ammonia to be supplied into a cracker (e.g., the cracker 100 in FIG. 1) based on the second signal.
[0075] According to an exemplary embodiment, the control unit 120 can check information regarding the preset temperature range from a storage unit (e.g., storage unit 150 in FIG. 2). The preset temperature range can include a first temperature range and a second temperature range. For example, the first temperature range and the second temperature range can be continuous temperature ranges that do not overlap with each other. A lower limit of the first temperature range can be greater than an upper limit of the second temperature range.
[0076] In one embodiment, the control unit 120 may determine the ammonia supply amount as a first capacity according to the second signal when the temperature of the cracker 100 is within the preset first temperature range. In one embodiment, the control unit 120 may determine the ammonia supply amount as a second capacity according to the second signal when the temperature of the cracker 100 is within the preset second temperature range. The first capacity may be smaller than the second capacity. The first temperature range, the second temperature range, the first capacity, and the second capacity may be experimental values, and may be stored as preset values according to the user's experimental results.
[0077] According to some embodiments, a threshold value may be assumed where the time or cost required to raise the temperature inside the cracker 100 is greater than the cost incurred by stopping the supply of ammonia. When the threshold value is approached, the control unit 120 may adjust the amount of ammonia supply by reducing or cutting off the supply of ammonia. The control unit 120 may adjust the amount of ammonia supply according to the second signal. According to the embodiment of FIG. 5, when reducing the amount of ammonia supply, the control unit 120 may change the reduction pattern of the amount of ammonia supply depending on the temperature range of the cracker 100 so that the maximum temperature raising effect is achieved depending on the situation inside the cracker 100.
[0078] FIG. 6 is a schematic flow chart illustrating the determination of ammonia feed rate based on the temperature of individual portions of the cracker of the ammonia reactor control system according to an exemplary embodiment of the present disclosure.
[0079] In step S610, a control unit (e.g., control unit 120 of FIG. 2) can receive temperature information of individual portions of a cracker (e.g., cracker 100 of FIG. 1). The control unit 120 can receive internal temperatures including a first portion and a second portion of the cracker 100. According to an exemplary embodiment, a sensor unit (e.g., sensor unit 110 of FIG. 2) can include multiple sensors and collect temperature information of the first portion and the second portion of the cracker 100.
[0080] The first and second portions may refer to non-overlapping portions of the cracker 100. In some embodiments, the first and second portions may be part of a portion where an ammonia supply (e.g., ammonia supply 140 in FIG. 2) is connected to the cracker.
[0081] The sensor unit 110 can measure the temperature of individual parts in the cracker 100, including the first and second parts of the cracker 100. The control unit 120 can determine a second signal according to the temperature of the individual parts in the cracker 100.
[0082] The second signal enables the ammonia reactor control system 10 to vary the pattern of the total ammonia feed to be provided to the first and second portions.
[0083] In one embodiment, the control unit 120 can change the supply position of ammonia. When the temperature of the first portion is higher than the temperature of the second portion, the control unit 120 can adjust the amount of ammonia supplied to the first portion and the amount of ammonia supplied to the second portion, out of the total amount of ammonia to be supplied, to be different via the second signal. For example, the control unit 120 performs control so as to provide the maximum temperature rise effect for efficient decomposition of ammonia. For example, when the temperature of the first portion is high, control can be performed so that a smaller amount of ammonia is supplied to the first portion than to the second portion.
[0084] In step S620, the control unit 120 can determine a second signal based on the temperature information of the individual parts. The control unit 120 can adjust the amount of ammonia supplied to the first part and the second part using the temperature information collected at the individual parts so as to maximize the temperature increase effect.
[0085] According to an exemplary embodiment, the control unit 120 can determine the first signal or the second signal based on temperature information, ammonia supply amount information, and hydrogen supply amount information. The control unit 120 can adjust the supply amount of ammonia or hydrogen so as to maximize the temperature increase effect based on various information collected by the ammonia reactor control system 10.
[0086] In one embodiment, the control unit 120 can set the total amount of ammonia or hydrogen supplied based on the same information so as to maximize the temperature increase effect, and can change the pattern of supplying ammonia or hydrogen to the cracker 100. For example, the control unit 120 can increase or decrease the amount of ammonia supplied and / or the amount of unreacted hydrogen supplied depending on the temperature of the cracker 100 to maintain an appropriate temperature inside the cracker 100. In addition, the control unit 120 can maintain the temperature inside the cracker 100 within an appropriate range to reduce the amount of residual ammonia.

The instructions may be stored in the form of program code, and a processor may generate program modules to perform the operations of the disclosed embodiments.
