Description

[Technical Field]

[0001] The present disclosure relates to systems and methods for controlling carbon sequestration. [Background technology]

[0002] In carbon sequestration, the number of process fluid emitters, particularly CO2 emitters, varies from project to project. The rate of process fluid production typically varies from emitter to emitter depending on factors including time of day, season, and product demand. The amount of emitters can vary over the life of a carbon capture utilization and storage (CCUS) facility. CCUS operators need to store CO2 using the least and lowest-cost energy.

[0003] Therefore, improved carbon sequestration is needed from a safety and cost perspective. Summary of the Invention

[0004] The object of the invention is defined by the subject matter of the independent claims. Further features of the invention are presented in the dependent claims.

[0005] According to one aspect, a system for controlling carbon sequestration includes: at least one emitter configured to output a process fluid containing carbon dioxide to be sequestered; at least one reservoir connected to the at least one emitter via a pipeline and configured to receive and store the process fluid; at least one compressor unit disposed in the pipeline between the at least one emitter and the at least one reservoir and configured to control a downstream pressure of the process fluid; at least one valve disposed in the pipeline between the at least one emitter and the at least one reservoir and configured to control a flow of the process fluid from the at least one emitter to the at least one reservoir; an optimizer unit configured to determine emitter output data by continuously recording an emitter output level of the process fluid of the at least one emitter, where the emitter output level is related to a quantity of the process fluid; and the optimizer unit configured to use the determined emitter output data to determine future emitter output data, where the future emitter output data is related to a prediction of the emitter output in a predetermined time window. The optimizer unit is configured to determine optimized control settings for controlling the transport of the process fluid using the determined future emitter output data, the optimized control settings including compressor unit settings and valve settings, where the compressor unit settings are used to control the at least one compressor unit and where the valve settings are used to control the at least one valve.

[0006] In other words, the optimizer unit is configured to evaluate different control setpoints, i.e., valve and compressor values, taking into account predicted future emitter output data, and find optimal control setpoints, particularly taking security and cost into consideration. In other words, the optimizer unit provides a relationship between different combinations of control setpoints in scenarios of future emitter output data to be isolated and the costs within the received boundaries. This allows the optimizer unit to find an optimal control point with the lowest cost for isolation that keeps the system within the received or predetermined boundaries.

[0007] Preferably, the at least one reservoir relates to any geological reservoir suitable for permanently storing a process fluid, in particular CO2. Furthermore, the at least one reservoir comprises an aquifer. In particular, each reservoir is accessed by a pipeline via a valve that makes it possible to regulate the flow of the process fluid into the reservoir. Even more preferably, each reservoir is accessed by at least one well connecting the pipeline to the reservoir. In this case, each of the at least one well is provided with a valve that makes it possible to regulate the flow of the process fluid into the well and thus into the reservoir.

[0008] Preferably, the optimizer unit includes a pipeline model, the pipeline model being associated with a virtual representation of the pipeline. More preferably, the optimizer unit uses the pipeline model to determine optimized control set points. In other words, the optimizer unit uses information provided by the pipeline model to evaluate how process parameters of the process fluid are most likely to behave in response to different control set points and determined future emitter output data.

[0009] Preferably, the optimizer unit is implemented in software.

[0010] The optimized setpoints are provided to the operator as recommended operating setpoints or are automatically applied to the control systems, particularly Level 2 control systems for automatic optimization of isolation.

[0011] Furthermore, the pipeline model includes pipeline integrity data regarding the integrity of the pipeline. In other words, if the integrity of a pipeline, particularly a branch of the pipeline, falls below a predetermined threshold, this path is temporarily excluded during fluid isolation. For example, due to pipeline overpressure, the integrity of the pipeline falls below the predetermined threshold. Therefore, this pipeline is no longer used for fluid isolation, even if this means that subsequent reservoirs cannot be used for fluid isolation.

[0012] As a result, an improved system for controlling fluid isolation is provided. In other words, the system enables dynamic operation and maintenance planning. Furthermore, the system can perform fluid isolation while taking into account costs, particularly energy costs. Therefore, the system makes it possible to provide process fluid isolation while maximizing the storage capacity of the reservoir and minimizing costs, particularly energy costs.

[0013] In a preferred embodiment, the system includes at least one process parameter sensor configured to determine a process parameter of the process fluid. The optimizer unit is configured to determine a future process parameter using the determined future emitter output data and the determined process parameter, where the future process parameter relates to a prediction of the process parameter in a predetermined time window. The optimizer unit is configured to determine optimized control set points using the determined future process parameter.

[0014] In other words, based on the future emitter output data, the optimizer unit knows the amount of process fluid that needs to be isolated in a given future time window. Using this information, the optimizer unit is configured to determine how the process parameters will change when isolating the process fluid according to the future emitter output data in response to optimized control setpoints. Thus, the optimizer unit is configured to determine optimized control setpoints that result in the process parameters with the lowest cost. In particular, because high pressure during isolation results in high energy consumption of at least one compressor unit, control setpoints that result in relatively high pressure of the process fluid usually result in relatively high costs.

[0015] The optimizer preferably includes a process model configured to determine future process parameters. For example, the optimizer unit may minimize compressor energy usage by adjusting compressor power while keeping each well / reservoir valve opening below operator-defined limits. Energy minimization is performed while respecting valve position constraints, thereby ensuring that local pressure control capabilities are maintained while minimizing overall energy consumption. The process model preferably includes a machine learning model.

[0016] Preferably, the system comprises a process storage infrastructure providing an intermediate storage volume for the process fluid, and the optimizer unit uses the process storage infrastructure to determine optimized control set points, i.e., utilizes this intermediate storage volume to influence operational decisions.

[0017] This allows for isolation of process fluids that can be optimized taking into account the expected amount of process fluid to be isolated and the expected process parameters that the isolation will result in.

[0018] In a preferred embodiment, the process parameters include fluid pressure, fluid temperature, composition, and / or fluid flow rate.

[0019] In a preferred embodiment, the optimizer unit is configured to receive a phase change margin for the process fluid relative to a physical boundary of a process parameter of the process fluid, taking into account changes in the physical state of the process fluid, and to determine an optimized control set point using the received phase change margin.

[0020] Preferably, process fluids, particularly those containing CO2, may have different physical states depending on the temperature and pressure of the process fluid. Generally, no change in the physical state of the process fluid should occur during transport of the process fluid, in other words, during isolation of the process fluid. As a result, depending on the provided phase change margin of the process fluid and the future process parameters of the process fluid, the optimizer unit can determine optimized control setpoints that enable isolation without change in the physical state of the process fluid.

[0021] The discharge and storage of process fluids is constantly balanced to keep the pressure within the desired range along the pipeline, especially when the process fluid is in the gas phase due to the need to control the gas packing phenomenon. Generally, the optimizer unit estimates the pressure, temperature, and composition of the process gas along the pipeline to calculate the margin from the phase changes.

[0022] In other words, changes in the physical state of the process fluid during isolation are likely to result in relatively high costs and pose security issues. As a result, the optimizer unit is configured to determine optimized control setpoints that result in a stable physical state of the process fluid.

[0023] In a preferred embodiment, at least one process parameter sensor is located in at least one compressor unit and / or at least one reservoir.

[0024] In a preferred embodiment, the optimizer unit is configured to receive scenario data relating to general information regarding carbon sequestration, and to use the scenario data to determine future emitter output data.

[0025] Preferably, the scenario data used herein includes time of day, season, and / or product demand. These factors relate to the amount of process fluid released. For example, during the day, there is generally a greater release of process fluid that needs to be isolated compared to nighttime.

[0026] In a preferred embodiment, the system comprises a reservoir model unit configured to provide a reservoir model for the at least one reservoir and configured to determine reservoir data using the reservoir model and the determined future emitter output data, the reservoir data relating to characteristics of the at least one reservoir when receiving process fluid according to the future emitter output data. The optimizer unit is configured to determine optimized control set points using the determined reservoir data.

[0027] The reservoir model preferably includes a virtual representation of at least one reservoir. Reservoir data provided by the reservoir model includes, for example, reservoir lifetime or maximum or current storage capacity. For example, the amount of pressure required to store process fluid in a reservoir is related to the reservoir's fill level. In other words, a higher reservoir fill level is associated with a higher pressure required to fill the reservoir with additional process fluid. The higher the process fluid pressure, the higher the isolation cost.

[0028] Furthermore, the reservoir data may include reservoir integrity data regarding the integrity of the reservoirs. In other words, the optimized settings may be determined taking into account the integrity of the available reservoirs. For example, if the integrity of one reservoir falls below a predetermined threshold, the reservoir may be temporarily excluded from fluid isolation.

[0029] The reservoir model is preferably configured to determine reservoir data using the determined future process parameters. In other words, the reservoir model predicts characteristics of at least one reservoir based on expected emitter outputs of the emitters and expected process parameters for a particular transport scenario.

[0030] As a result, information about the reservoir can be used by the optimizer unit to find optimized control settings for sequestration.

[0031] In a preferred embodiment, the system comprises a plurality of compressor units, and the optimizer unit is configured to balance the workload of the plurality of compressor units relative to one another when determining the optimized control settings.

[0032] Balancing the workload of multiple compressor units directly translates into reduced maximum process fluid pressure, which directly translates into reduced isolation costs.

[0033] As a result, the optimizer unit is able to balance the compressor settings to provide better optimized control settings.

[0034] In a preferred embodiment, the system comprises multiple reservoirs and the optimizer unit is configured to balance the process fluid intake loads between the multiple reservoirs when determining the optimized control setpoints.

[0035] As previously explained, less energy is required to fill a less filled reservoir than a nearly full reservoir. Taking into account reservoir fill levels and balancing the process fluid intake load among the available reservoirs allows for improved optimized set points.

[0036] As a result, the optimizer unit is able to balance the valve settings to provide better optimized control settings.

[0037] In a preferred embodiment, the at least one reservoir comprises a plurality of injection wells used to inject process fluid from at least one emitter into the at least one reservoir, and the optimizer unit is configured to balance the process fluid intake load among the plurality of injection wells when determining the optimized control setpoints.

[0038] Thus, the well head pressure, which is related to the pressure in the head of the well, can be controlled.

[0039] In a preferred embodiment, the optimizer unit is configured to receive energy cost data, and the optimizer unit is configured to determine optimized control settings using the received energy cost data.

[0040] In other words, the optimizer unit is provided with current energy prices and / or future price estimates. As a result, the optimizer unit can allocate process fluid to wells while balancing reservoir utilization over a selectable time range, such as a week, taking energy costs into account. For example, when energy prices are high, the optimizer may favor the use of wells and / or reservoirs that consume less energy, taking into account pipeline backpressure and distance, and when prices are low, it may use wells and / or reservoirs that incur higher energy consumption, thus minimizing energy costs.

[0041] In a preferred embodiment, the optimizer unit is configured to receive safety parameters, and the optimizer unit is configured to use the received safety parameters to determine optimized control settings.

[0042] In other words, the safety parameters for all transport, compression equipment, wells and reservoirs are boundary conditions within the optimization of the optimizer unit.

[0043] The system therefore makes it possible to provide process fluid isolation with improved safety, particularly in combination with maximizing reservoir storage capacity and minimizing costs.

[0044] In a preferred embodiment, the system includes a temperature regulator configured to externally regulate the temperature of the process fluid, the optimizer unit configured to determine a temperature control signal when determining an optimized control setpoint, and the temperature regulator configured to regulate the temperature of the process fluid using the temperature control signal.

[0045] In a preferred embodiment, the optimizer unit comprises a machine learning unit.

[0046] Preferably, the optimizer uses artificial intelligence, including physical modeling, advanced process control, model predictive control, and / or machine learning.

[0047] According to one aspect of the present invention, a method for controlling process fluid isolation includes the steps of outputting a process fluid to be collected by at least one emitter; receiving and storing the process fluid by at least one reservoir connected to the at least one emitter via a pipeline; controlling a downstream pressure of the process fluid by at least one compressor unit disposed in the pipeline between the at least one emitter and the at least one reservoir; and controlling a downstream pressure of the process fluid from the at least one emitter to the at least one reservoir by at least one valve disposed in the pipeline between the at least one emitter and the at least one reservoir. The method includes the steps of: controlling a flow of a fluid; determining, by an optimizer unit, emitter output data by continuously recording an emitter output level of at least one emitter, where the emitter output level is related to a quantity of the process fluid; determining, by the optimizer unit, future emitter output data using the determined emitter output data; where the future emitter output data is related to a prediction of the emitter output in a predetermined time window; and determining, by the optimizer unit, optimized control settings for controlling the transport of the process fluid using the determined future emitter output data. The optimized control settings include a compressor unit setpoint and a valve setpoint, where the compressor unit setpoint is used to control the at least one compressor unit and the valve setpoint is used to control the at least one valve.

[0048] The subject matter of the present invention will be explained in more detail in the following text with reference to preferred exemplary embodiments illustrated in the accompanying drawings. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0052] FIG. 1 shows a schematic diagram of a system 100 for controlling carbon sequestration. The system 100 includes at least one emitter 10, at least one reservoir 20, at least one compressor unit 30, and at least one valve 40. In this example, the system 100 includes multiple emitters 10, e.g., three emitters 10, configured to output a process fluid 11 containing carbon dioxide. The system 100 is configured to isolate the process fluid 11 from the emitters 10 to a reservoir 20 configured to receive and store the process fluid 11. The reservoir 20 is connected to the emitters 10 via a pipeline 70, specifically a pipeline system including multiple pipeline branches. Between the emitters 10 and the reservoir 20, multiple compressor units 30, e.g., three compressor units 30, are disposed in the pipeline 70. The compressor units 30 apply pressure to the process fluid 11 in the pipeline 70 for transporting the process fluid 11 through the pipeline 70. For example, each branch of the pipeline 70 is supplied with a compressor unit 30. The reservoir 20 is accessed by a pipeline 70 through a number of wells, each well being provided with a valve 40. The valves 40 are configured to control the flow of process fluid 11 within the pipeline 70, particularly into the wells leading to the reservoir 20.

[0053] Carbon sequestration, i.e., the isolation of the process fluid 11, is controlled by an optimizer unit 50, which is part of the system 100. The optimizer unit 50 is preferably implemented as a software module. To control the isolation of the process fluid 11, the optimizer unit 50 provides optimized control settings S. The optimized control settings include the settings, i.e., control settings, of the compressor unit 30 and the valves 40. Thus, the optimizer unit 50 is configured to control the pressure and flow of the process fluid 11 in the pipeline 70. Furthermore, the optimizer unit 50 is configured to define different paths for the process fluid 11 through the pipeline 70 from the emitter 10 to the reservoir 20 and the amount of process fluid 11 that flows through each path in the pipeline 70. The optimized control settings S are control settings S optimized by the optimizer unit 50, taking into account, among other things, general transportation costs, energy consumption for sequestration, and maximizing the storage capacity of the reservoir 20 and / or well. The optimized control setpoints S include a compressor unit setpoint SC used to control the compressor unit 30 and a valve setpoint SV used to control the valve 40 .

[0054] The optimizer unit 50 is configured to continuously monitor, i.e., record, the emitter output level of the process fluid 11 from the emitter 10. In other words, the optimizer unit 50 is configured to monitor the amount of process fluid 11 emitted by the emitter 10, particularly over a predetermined time window. Based on the monitoring, the optimizer unit 50 determines emitter output data DO for the emitted process fluid 11. The optimizer unit 50 is further configured to use the determined emitter output data DO to determine future emitter output data DOF. In other words, the optimizer unit 50 is configured to predict the emitter output level output by the emitter, particularly over a predetermined time window. Therefore, the optimizer unit 50 may also include scenario data Ds provided to the optimizer unit 50 and comprising general information regarding carbon sequestration. In particular, the date and time of carbon sequestration are a key factor in predicting the future emitter output data DOF. Using the determined future emitter output data DOF, the optimizer unit 50 determines optimized control set points S, thus providing improved carbon sequestration.

[0055] Preferably, the optimizer unit 50 includes a process model, in particular a machine learning model, that provides a model of the transport process of the process fluid 11 from the emitter 10 to the reservoir 20. The process model is configured to provide predictions of the transport of the process fluid 11 that are used by the optimizer unit 50 to determine optimized control set points.

[0056] The system 100 includes a plurality of process parameter sensors 80 configured to determine process parameters PP of the process fluid 11. The process parameter sensors 80 are located, inter alia, near the compressor unit 30 and the valves 40. However, the process parameter sensors 80 may be located along the pipeline 70 whenever information on the process parameters PP is useful or necessary. The process parameters PP include the fluid pressure, fluid temperature, fluid composition, and / or fluid flow rate of the process fluid 70. The process parameters PP are provided to the optimizer unit 50. The optimizer unit 50 is configured to determine future process parameters using the determined future emitter output data DOF and the determined process parameters PP. The future process parameters are predictions and / or simulations of process parameters for a predetermined time window in the future. The process model of the optimizer unit 50 preferably uses the determined process parameters PP and the future emitter output data DOF to determine future process parameters, inter alia, based on different compressor unit setpoints SC and / or valve setpoints SV. In other words, the process model provides a simulation for the optimizer unit 50, predicting how the process parameters PP will change based on different scenarios for the compressor unit setpoints SC and valve setpoints SV. As a result, the optimizer unit 50 can evaluate which setpoints will result in optimal carbon sequestration based on the determined future process parameters, taking into account, among other things, the general transportation costs, the energy consumption of sequestration, and maximizing the storage capacity of the reservoir 20 and / or well. The optimizer unit 50 preferably considers additional factors in the optimization process. For example, the process parameters PP should all be applied within the provided security constraints. Furthermore, based on the process parameters PP, particularly fluid pressure and fluid temperature, the physical state of the process fluid 11 may change during transportation. This change in the physical state of the process fluid 11 typically results in increased energy consumption and, therefore, increased costs.Therefore, a phase change margin related to the physical boundaries of the process parameter PP that takes into account changes in the physical state of the process fluid 11 can be provided to the optimizer unit 50. Thus, the optimizer unit 50 is most likely to determine an optimized control setpoint S that does not result in changes in the physical state of the process fluid 11 during transport from the emitter 10 to the reservoir 20.

[0057] The system 100 further comprises a reservoir model unit 60 configured to provide a reservoir model of the reservoir 20 and / or the well. The reservoir model 60 provides reservoir data DR based on future emitter output data DOF and / or future process parameters. Thus, the optimizer unit 50 can determine optimized control set points S using the reservoir data DR.

[0058] To evaluate the cost of carbon sequestration, optimizer unit 50 is provided with energy cost data DE from an external data source 90, e.g., a cloud environment. The energy cost data DE preferably includes future energy costs. In other words, the energy cost data DE reflects the predicted energy costs of carbon sequestration for a predetermined time period into the future. As a result, optimizer unit 50 is configured to determine optimized control setpoints S using the energy cost data DE.

[0059] 2 shows a schematic diagram of the optimizer unit 50. The optimizer unit 50 comprises an emitter analysis unit 51 and a setpoint analysis unit 52. The emitter analysis unit 51 is provided with emitter output data DO and scenario data DS to provide future emitter output data DOF. The future emitter output data DOF is provided to the setpoint analysis unit 52. The setpoint analysis unit 52 is also provided with process parameters PP, phase change margin M, reservoir data DR, energy cost data DE, and safety parameters PS. The setpoint analysis unit 52 is configured to provide an optimized control setpoint S based on all available inputs.

[0060] 3 shows a schematic diagram of a method for controlling carbon sequestration, including the following steps: at least one emitter 10 outputs S10 a process fluid 11 to be recovered; at least one reservoir 20 connected to the at least one emitter 10 via a pipeline 70 receives and stores S20 the process fluid 11, and at least one compressor unit 30 disposed in the pipeline 70 between the at least one emitter 10 and the at least one reservoir 20 controls S30 a downstream pressure of the process fluid 11; at least one valve 40 disposed in the pipeline 70 between the at least one emitter 10 and the at least one reservoir 20 controls S40 a flow of the process fluid 11 from the at least one emitter 10 to the at least one reservoir 20; and an optimizer unit 50 determines emitter output data DO by continuously recording an emitter output level of the at least one emitter 10, the emitter output level being related to the amount of the process fluid 11 S50. The optimizer unit 50 uses the determined emitter output data DO to determine future emitter output data DOF, where DOF is related to a prediction of the emitter output over a predetermined time window S60. The optimizer unit 50 uses the determined future emitter output data DOF to determine S70 optimized control setpoints S for controlling the transport of the process fluid 11. The optimized control setpoints S are determined by the compressor unit setpoints SC and a valve setpoint SV, where the compressor unit setpoint SC is used to control at least one compressor unit 30 and the valve setpoint SV is used to control at least one valve 40.
