Description

Technical Field

[0001] The present disclosure relates to an ammonia reactor control system and a hydrogen generation method. Background Art

[0002] For example, in an operation of changing the amount of ammonia decomposition according to the state of a running vehicle using a fuel cell, the ammonia supply amount is controlled differently according to the temperature of a decomposer (eg, a reactor), thereby stabilizing the ammonia decomposition rate in the reactor caused by changes in the reactor temperature.

[0003] During such load following operation, if the amount of ammonia supplied to the reactor is increased to increase hydrogen production in a short period of time, the temperature inside the reactor will drop because the temperature of the supplied ammonia is generally room temperature.

[0004] If the temperature inside the decomposer drops temporarily, the ammonia decomposition rate decreases due to deactivation of the catalyst inside the decomposer or a decrease in the overall performance of the device. As a result, the amount of residual ammonia in the device may increase. Since the residual ammonia is supplied to the adsorption tower or fuel cell, it may cause a decrease in the overall performance of the device or an unexpected failure. Summary of the invention

Each configuration / node can send and receive data with other configurations / nodes. The configurations / nodes can be connected via a network.

[0044] The ammonia reactor control system 10 according to various embodiments of the present disclosure may receive ammonia (NH 3) and decompose it through the decomposer 100. If the internal temperature of the decomposer 100 temporarily decreases, the ammonia decomposition rate may decrease due to deactivation or performance degradation of the catalyst inside the decomposer 100. Therefore, the amount of residual ammonia in the decomposer 100 may increase relatively.

[0048] Reference Figure 2 , the ammonia reactor control system 10 may include a decomposer 100, a sensor unit 110, a control unit 120, a hydrogen supply unit 130, an ammonia supply unit 140, and a storage unit 150. The internal configuration included in the ammonia reactor control system 10 may include Figure 1 The absorption unit 200, the fuel cell 300, etc. are shown, but are not limited thereto.

[0049] In some embodiments, the functions of the control unit 120 may be performed by a separate processing server or a cloud server instead of the control unit 120 .

[0050] According to an exemplary embodiment, the reactor of the ammonia reactor control system 10 may refer to a device such as a cracker 100 .

[0051] 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 ammonia supply amount and hydrogen supply amount supplied to the decomposer 100 of the ammonia reactor control system 10 from the ammonia supply unit 140 and the hydrogen supply unit 130, respectively.

[0052] The control unit 120 may receive the internal temperature information of the decomposer 100 from the sensor unit 110. The control unit 120 may receive the internal temperature of the first part and the second part of the decomposer 100.

The first part and the second part may refer to the parts of the decomposer 100 that do not overlap with each other. In some embodiments, the first part and the second part may be a part of the part where the ammonia supply unit 140 and the decomposer 100 are connected.

[0053] According to an exemplary embodiment, the hydrogen supply unit 130 may determine the hydrogen supply amount supplied to the inside of the decomposer 100 according to the first signal of the control unit 120. The hydrogen supply amount supplied to the decomposer 100 may be adjusted according to the first signal of the control unit 120.

[0054] According to an exemplary embodiment, the ammonia supply unit 140 may determine the ammonia supply amount supplied to the inside of the decomposer 100 according to the second signal of the control unit 120. The ammonia supply amount supplied to the decomposer 100 may be adjusted according to the second signal of the control unit 120.

[0055] According to an exemplary embodiment, the storage unit 150 may store data supporting various functions of the ammonia reactor control system 10 and a program for controlling the operation of the control unit 120. The storage unit 150 may store input / output data (e.g., images, videos, etc.), and the storage unit 150 may store a plurality of application programs (or applications) running in the ammonia reactor control system 10, data for the operation of the ammonia reactor control system 10, and instructions. At least one of the application programs may be downloaded from an external server through wireless communication.

[0056] The storage unit 150 may include at least one type of storage medium selected from Network Attached Storage (NAS), flash memory type, hard disk type, SSD type (Solid State Disk type), SDD type (Silicon Disk Drive type), multimedia card micro type, card type memory (e.g., SD or XD memory, etc.), RAM (random access memory), SRAM (static random access memory), ROM (read-only memory), EEPROM (electrically erasable programmable read-only memory), PROM (programmable read-only memory), magnetic memory, magnetic disk, and optical disk.

[0057] The ammonia reactor control system 10 may further include an output unit (not shown). The output unit may generate output related to vision, hearing, touch, etc., and may include a display unit.

[0058] The display unit may form an interlayer structure with the touch sensor, or may be provided in an integrated structure with the touch sensor to realize a touch screen. The touch screen may be provided as a user input unit, which provides an input interface between the ammonia reactor control system 10 and the user, and may provide an output interface between the ammonia reactor control system 10 and the user.

[0059] The display unit displays (outputs) information processed in the ammonia reactor control system 10. For example, the display unit may display execution screen information of an application program (e.g., an application) running in the ammonia reactor control system 10, or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information.

[0060] Can be used with Figure 2The performance of the configurations shown corresponds to adding or deleting at least one configuration. In addition, those skilled in the art will readily appreciate that the relative positions of the configurations may be changed according to the performance or structure of the ammonia reactor control system 10.

[0061] on the other hand, Figure 2 Each configuration shown in the EMBODIMENTS may refer to software and / or hardware configurations such as a Field Programmable Gate Array (FPGA) and an Application Specific Integrated Circuit (ASIC).

[0062] Figure 3 is a schematic flowchart for explaining a control method of an ammonia reactor control system according to an exemplary embodiment of the present disclosure.

[0063] Reference Figure 3 , ammonia reactor control systems (e.g. Figure 1 The ammonia reactor control system 10) can be controlled by a decomposer (e.g., Figure 1 The amount of heat absorbed inside the decomposer 100 is calculated based on the internal temperature information of the decomposer 100 to temporarily reduce the output of the fuel cell.

[0064] In step S310, a control unit (eg, Figure 2 The control unit 120 of the ammonia supply unit (eg, Figure 2 The control unit 120 may receive the ammonia supply amount information through a separate flow meter or supply amount measuring device installed in the ammonia supply unit 140 .

[0065] In step S320, the control unit 120 may confirm the preset heat supply information. Considering the stability of the hydrogen reaction, the ammonia reactor control system 10 may adjust the hydrogen supply mode differently through the first signal to induce an improved warming effect. For example, the same total amount of hydrogen supply may be supplied by changing the mode.

[0066] The control unit 120 can retrieve information from a storage unit (eg, Figure 2 The control unit 120 may confirm the preset heat supply amount information based on the information provided by the sensor unit (eg, Figure 2 The temperature information received by the sensor unit 110 is used to calculate the internal heat absorption information of the decomposer 100.

[0067] In step S340, the control unit 120 can temporarily reduce the output of the fuel cell 300 by comparing the preset heat supply information with the internal heat absorption information of the decomposer 100. For example, the temporary time can be about 3 to 5 seconds, which can be changed according to experimental values. The preset heat supply information can correspond to the threshold value of the internal heat absorption of the decomposer 100.

[0068] According to an exemplary embodiment, the preset heat supply amount may be set to a heat supply amount capable of preventing the internal temperature of the decomposer 100 from being lowered due to excess ammonia or excess hydrogen inside the decomposer.

[0069] The control unit 120 may determine the first signal based on the temperature information and the ammonia supply information. The first signal of the control unit 120 may be used to control the internal temperature increase effect of the decomposer through the preset heat supply information.

[0070] According to an exemplary embodiment, when the internal heat absorption of the decomposer is lower than the preset heat supply, the control unit 120 can increase the hydrogen supply through the first signal to increase the internal temperature of the decomposer 100. Therefore, the temperature increase effect in the ammonia reactor control system 10 can be amplified.

[0071] According to an exemplary embodiment, when the temperature of the decomposer 100 decreases, the control unit 120 may increase the hydrogen supply from the fuel cell 300. Therefore, the control unit 120 may quickly increase the temperature of the decomposer 100. When determining the hydrogen supply, the control unit 120 may change the hydrogen supply mode to produce the greatest possible warming effect in consideration of the stability of the hydrogen reaction.

[0072] Figure 4 is a schematic flow chart for explaining ammonia preheating of an ammonia reactor control system according to an exemplary embodiment of the present disclosure.

[0073] In step S410, a control unit (eg, Figure 2 The control unit 120 may receive a supply to a decomposer (eg, Figure 1 The control unit 120 may receive the ammonia temperature information inside the decomposer 100. The control unit 120 may receive the ammonia temperature information through a separate temperature sensing unit 60 for sensing the temperature of ammonia supplied to the inside of the decomposer 100.

[0074] In step S420, the control unit 120 may determine a third signal based on the ammonia temperature information. The control unit 120 may preheat the ammonia before supplying the ammonia to the decomposer according to the third signal. Figure 1The ammonia reactor control system 10 of the present invention may further include a preheating unit 50, which preheats the ammonia supplied to the decomposer 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 provided at any position capable of preheating the ammonia inside the ammonia supply unit 140.

[0075] According to an exemplary embodiment, the control unit 120 may receive ammonia temperature information in the ammonia supply unit 140 from the temperature sensing unit 60. Therefore, the control unit 120 may confirm whether the temperature of ammonia to be supplied to the decomposer 100 through the ammonia supply unit 140 is lower than the temperature of ammonia already present in the decomposer 100.

[0076] In one embodiment, when the temperature of ammonia in the ammonia supply unit 140 is lower than the temperature of ammonia in the decomposer 100 , the control unit 120 may operate the preheating unit to increase the temperature of ammonia in the ammonia supply unit 140 according to the third signal.

[0077] In one embodiment, when the temperature of ammonia to be supplied to the ammonia supply unit 140 in the decomposer 100 is low, the control unit 120 may operate the preheating unit according to the third signal to increase the temperature of ammonia in the ammonia supply unit 140 in advance.

[0078] As described above, it is possible to control the cause of the temperature drop inside the decomposer 100. For example, the temperature control can be performed using the mechanism of ammonia decomposition, which is an endothermic reaction.

[0079] According to an exemplary embodiment, the preheating unit may include a material having high thermal conductivity and large heat capacity. The preheating unit may be made of a material capable of uniformly transferring heat when preheating ammonia.

[0080] Figure 5 is a schematic flowchart for explaining determination of an ammonia supply amount of an ammonia reactor control system according to an exemplary embodiment of the present disclosure.

[0081] In step S510, a control unit (eg, Figure 2 The control unit 120 may be supplied from a hydrogen supply unit (eg, Figure 2 The control unit 120 may receive the hydrogen supply amount information through a separate flow meter or supply amount measuring device installed in the hydrogen supply unit 130.

[0082] In step S520, the control unit 120 determines the ammonia supply amount according to a preset temperature range. The control unit 120 can determine the amount of ammonia supplied to the decomposer (e.g., Figure 1 The ammonia supply amount inside the decomposer 100).

[0083] According to an exemplary embodiment, the control unit 120 may store the data from a storage unit (eg, Figure 2 The storage unit 150 of the embodiment of the present invention confirms the information of the preset temperature range. The preset temperature range may include a first temperature range and a second temperature range. For example, the first temperature range and the second temperature range may be continuous temperature ranges that do not overlap with each other. The lower limit of the first temperature range may be greater than the upper limit of the second temperature range.

[0084] In one embodiment, when the temperature of the decomposer 100 is within the preset first temperature range, the control unit 120 may determine the ammonia supply as the first capacity according to the second signal. In one embodiment, when the temperature of the decomposer 100 is within the preset second temperature range, the control unit 120 may determine the ammonia supply as the second capacity according to the second signal. 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.

[0085] According to some embodiments, it may be assumed that the time or cost required to increase the internal temperature of the decomposer 100 is greater than a threshold value of the cost of interrupting the ammonia supply. When approaching the threshold value, the control unit 120 may adjust the ammonia supply by reducing or blocking the ammonia supply. The control unit 120 may adjust the ammonia supply according to the second signal. Figure 5 In an embodiment, when reducing the ammonia supply, the control unit 120 may change the ammonia supply reduction mode according to the temperature range of the decomposer 100 to generate the maximum temperature increase effect as much as possible according to the internal conditions of the decomposer 100.

[0086] Figure 6 is a schematic flowchart for explaining determination of an ammonia supply amount based on temperatures of various parts of a decomposer of an ammonia reactor control system according to an exemplary embodiment of the present disclosure.

[0087] In step S610, a control unit (eg, Figure 2 The control unit 120) may receive a decomposer (eg, Figure 1 The control unit 120 may receive the internal temperature of the first part and the second part of the decomposer 100. According to an exemplary embodiment, the sensor unit (eg, Figure 2 The sensor unit 110 includes a plurality of sensors, which can collect temperature information of the first part and the second part of the decomposer 100 .

[0088] The first portion and the second portion may refer to portions of the decomposer 100 that do not overlap with each other. In some embodiments, the first portion and the second portion may be an ammonia supply unit (e.g., Figure 2 A portion of the portion where the ammonia supply unit 140) and the decomposer are connected.

[0089] The sensor unit 110 may measure the temperature of each portion inside the decomposer 100 including the first portion and the second portion of the decomposer 100. The control unit 120 may determine a second signal according to the temperature of each portion inside the decomposer 100.

[0090] According to the second signal, the ammonia reactor control system 10 may change a pattern of the total amount of ammonia supply to be supplied to the first portion and the second portion.

[0091] In one embodiment, the control unit 120 may change the supply position of ammonia. When the temperature of the first part is higher than the temperature of the second part, the control unit 120 may adjust the amount of ammonia supplied to the first part and the amount of ammonia supplied to the second part in the total amount of ammonia supply to be supplied differently according to the second signal. For example, the control unit 120 controls to induce the greatest possible warming effect in order to effectively decompose ammonia. For example, when the temperature of the first part is high, it may be controlled so that the amount of ammonia supplied to the first part is less than the amount of ammonia supplied to the second part.

[0092] In step S620, the control unit 120 may determine a second signal based on the temperature information of each portion. The control unit 120 may adjust the amount of ammonia supplied to the first portion and the second portion using the temperature information collected from each portion to produce the greatest possible warming effect.

[0093] According to an exemplary embodiment, the controller 120 may determine the first signal or the second signal based on temperature information, ammonia supply information, and hydrogen supply information. The control unit 120 may adjust the ammonia supply or the hydrogen supply based on various information collected by the ammonia reactor control system 10 to produce the greatest possible warming effect.

[0094] In one embodiment, the control unit 120 can set the total supply of ammonia or hydrogen based on the same information to produce the maximum temperature increase effect as much as possible, and change the mode of supplying ammonia or hydrogen to the decomposer 100. For example, the control unit 120 can increase or decrease the supply of ammonia and / or the supply of unreacted hydrogen according to the temperature of the decomposer 100 to maintain the inside of the decomposer 100 at an appropriate temperature. In addition, the control unit 120 can reduce the amount of residual ammonia by maintaining the internal temperature of the decomposer 100 within an appropriate range.

[0095] In some embodiments, the disclosed embodiments may be implemented in the form of a recording medium storing instructions executable by a computer. The instructions may be stored in the form of program code, and when the instructions are executed by a processor, a program module may be generated to perform the operations of the disclosed embodiments.
