Plug flow is a special flow pattern in which gas and liquid advance alternately in a plug-like manner. This flow pattern can lead to pressure fluctuations and uneven flow rates within the pipeline. These fluctuations not only affect the stability of the cryogenic fractionation process but can also cause equipment wear and increased energy consumption, thereby reducing the overall system efficiency. Therefore, how to effectively eliminate plug flow and optimize the flow state within the pipeline to improve the stability and efficiency of cryogenic fractionation is a pressing issue in current technology.

[0026] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0027] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The main solutions of the embodiments of this application are: In this embodiment, for ease of description, the following description will be made with the plunger flow elimination device as the execution subject.

[0029] Due to existing technology, plug flow often occurs within pipelines. Plug flow is a special flow pattern in which gas and liquid alternately advance in a plug-like manner. This flow pattern can cause pressure fluctuations and uneven flow rates within the pipeline. These fluctuations not only affect the stability of the cryogenic fractionation process but can also cause equipment wear and increased energy consumption, thereby reducing the efficiency of the entire system.

[0030] The present application provides a solution, which enables: first, in response to a plunger flow detection instruction, the parameters of the gas-liquid two-phase fluid in the gas-liquid two-phase pipeline are obtained; then, based on the parameters and a preset gas-liquid two-phase fluid state detection strategy, the state of the gas-liquid two-phase fluid is determined; further, if the state is a plunger flow, based on a preset plunger flow elimination strategy, a target gas for eliminating the plunger flow is generated; finally, the target gas is introduced into the gas-liquid two-phase pipeline to eliminate the plunger flow.

[0031] It can be understood that this application selects relevant formulas to calculate based on the type corresponding to the pipeline to determine whether there is a plunger flow. If so, based on the preset plunger flow elimination strategy, it determines the best method to convert the plunger flow into other flows. Based on the best method, the above formula is used to reversely deduce the gas required to destroy the plunger flow, and the gas is introduced into the plunger flow to destroy the plunger flow.

[0032] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of performing the above functions, such as a plunger flow elimination device. The following uses the plunger flow elimination device as an example to illustrate this embodiment and the following embodiments.

[0033] Based on this, the embodiment of the present application provides a method for eliminating plunger flow, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the plunger flow elimination method of the present application.

[0034] In this embodiment, the plunger flow elimination method includes steps S10 to S40: Step S10, in response to the plunger flow detection instruction, obtaining parameters of the gas-liquid two-phase fluid in the gas-liquid two-phase pipeline; It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of performing the above functions, such as a plunger flow elimination device. The following uses the plunger flow elimination device as an example to illustrate this embodiment and the following embodiments.

[0035] It's important to note that plug flow is a special type of fluid flow pattern, typically referring to a fluid moving in a plug-like manner (similar to piston motion) through a pipeline. This flow pattern can occur in certain industrial pipeline systems (such as oil and gas pipelines), especially when the fluid phases are complex (e.g., gas-liquid).

[0036] A detection instruction is a signal or command that triggers a detection operation. It may be triggered by manual operation, an automated control system, or a sensor to start the detection of the fluid status in the pipeline.

[0037] Gas-liquid two-phase flow refers to a fluid that exists simultaneously in both gas and liquid phases within a pipeline. In this case, the flow characteristics of the fluid are more complex than those of single-phase fluids because the gas and liquid have significantly different physical properties, such as density and viscosity, and their interaction affects the overall flow behavior.

[0038] A pipeline is a channel for fluid flow and a carrier for fluid transportation. In this case, the fluid status in the pipeline needs to be monitored and analyzed.

[0039] Parameters are physical quantities that describe the state of a fluid, such as velocity, flow rate, pressure, temperature, and gas-liquid holdup (the ratio of gas to liquid). These parameters are crucial for understanding fluid flow characteristics, optimizing pipeline transportation efficiency, and ensuring safe pipeline operation.

[0040] In this application, upon receiving a command specifically for detecting plunger flow, the system initiates a detection program to measure and acquire various parameters of the gas-liquid two-phase flow in the pipeline. These parameters may include gas and liquid flow rate, flow rate, pressure, temperature, etc., which are used to analyze the flow state of the fluid in the pipeline for further processing or decision-making.

[0041] Specific application scenarios can be: Taking air separation as an example, the most commonly used method is cryogenic distillation. This method converts air into a liquid form through a compression cycle followed by deep freezing. Cryogenic distillation then gradually separates the liquid air into inert gases such as oxygen, nitrogen, and argon based on their boiling points. During this process, both gas and liquid are present in the distillation pipeline. By monitoring the plunger flow and obtaining relevant parameters, air separation efficiency can be optimized and pipeline blockages prevented.

[0042] Step S20, determining the state of the gas-liquid two-phase fluid based on the parameters and a preset gas-liquid two-phase fluid state detection strategy; Presets refer to pre-defined rules, models, or algorithms used to analyze and judge fluid conditions. These strategies are usually developed based on experience, experimental data, or theoretical models.

[0043] Gas-liquid two-phase fluid state detection strategies refer to rules or methods specifically used to analyze the state of gas-liquid two-phase fluids. These strategies include: threshold determination, for example, determining a specific state when the gas-liquid holdup exceeds a certain threshold; pattern recognition, identifying fluid states by analyzing parameter variation patterns (such as flow rate fluctuations or periodic pressure changes); and machine learning models, using trained models (such as neural networks and support vector machines) to classify or predict parameters.

[0044] It should be noted that the states of the gas-liquid two-phase fluid include plug flow state, block flow state, bubbly flow state, stratified flow state, wavy flow state, etc.

[0045] In this embodiment, the specific state of the gas-liquid two-phase fluid (such as plunger flow state, block flow state, bubbly flow state, stratified flow state, wavy flow state, etc.) is determined by analyzing the acquired fluid parameters (such as flow velocity, flow rate, pressure, etc.) and combining them with a pre-set gas-liquid two-phase fluid state detection strategy (such as threshold judgment, pattern recognition or machine learning model).

[0046] It should be noted that in order to determine whether the gas-liquid two-phase flow is a plug flow, the following key parameters need to be measured: Flow velocity (v): the flow rate of gas and liquid.

[0047] Gas-liquid holdup (α): the ratio of gas volume to total volume.

[0048] Pipe diameter (D): The inside diameter of the pipe.

[0049] Physical properties of fluids: such as the density of gases and liquids ( and ) and viscosity ( and ).

[0050] Plug flow usually occurs at high flow rates and high gas-liquid holdup. The following empirical formula can be used for preliminary judgment:

[0051] Where: Re is the Reynolds number, which is used to judge the flow state. is the density of the fluid, is the flow rate of the fluid, D is the pipe diameter, is the dynamic viscosity of the fluid.

[0052] For gas-liquid two-phase flow, the Reynolds numbers for the gas and liquid can be calculated separately. If the gas Reynolds number is high (usually >4000), plug flow may be formed.

[0053] At the same time, the gas-liquid holdup ( ) is also an important parameter for determining plug flow. Generally speaking, when the gas-liquid phase fraction is high (e.g. >0.3), plug flow is more likely to form.

[0054] You can refer to flow pattern diagrams for gas-liquid two-phase flow, such as Beggs-Brill or Mandhane diagrams, which identify flow patterns based on gas-liquid holdup and flow velocity. For example, if the gas-liquid holdup is high and the flow velocity is high, it will generally fall into the plug flow region.

[0055] Specifically, the step of determining the state of the gas-liquid two-phase fluid based on the parameters and a preset gas-liquid two-phase fluid state detection strategy further includes steps S21 to S24: Step S21, determining the pipeline type corresponding to the gas-liquid two-phase pipeline; It should be noted that, in this application, the pipeline type refers to a horizontal pipeline or a vertical upward pipeline.

[0056] Furthermore, it should be noted that different pipeline types require different methods for determining the state of the gas-liquid two-phase flow. For example, in horizontal pipelines, the Mendehan or Burke flow patterns are appropriate; in vertical pipelines, the Hewitt flow pattern is appropriate.

[0057] Step S22, determining a target algorithm and a target flow pattern for determining the state of the gas-liquid two-phase fluid in the gas-liquid two-phase pipeline based on the pipeline type and the preset gas-liquid two-phase fluid state detection strategy; The target algorithm is a specific algorithm selected from pre-set detection strategies to analyze the gas-liquid two-phase flow state in the pipeline. The algorithm chosen depends on the pipeline type and fluid characteristics. For example, if the pipeline is used for high-velocity transportation, an algorithm based on the Reynolds number might be selected to determine the flow pattern. If the pipeline is equipped with a heater, an algorithm that considers temperature effects might be selected. If the pipeline has a complex flow pattern, a machine learning-based algorithm might be selected.

[0058] The target flow pattern refers to a flow pattern diagram used to determine the state of the fluid, such as the Mendheim flow pattern, Burke flow pattern, and Hewitt flow pattern.

[0059] In this embodiment, based on the determined pipeline type and the preset gas-liquid two-phase fluid state detection strategy (such as threshold judgment, pattern recognition, machine learning model, etc.), a most suitable algorithm (target algorithm) is selected, and a flow pattern diagram (target flow pattern) for judging the gas-liquid two-phase fluid state in the pipeline is determined.

[0060] Step S23: determining the state of the gas-liquid two-phase fluid based on the target algorithm, the parameters and the target flow pattern.

[0061] In this embodiment, appropriate algorithms and flow patterns are selected based on specific application scenarios (pipeline types), which can be applied to various industrial scenarios, such as air separation, oil and gas pipeline monitoring, chemical process control, and environmental monitoring, to optimize operating conditions and improve efficiency and safety.

[0062] Step S30, if the state is plunger flow, generating a target gas for eliminating the plunger flow based on a preset plunger flow elimination strategy; A preset plug flow elimination strategy is a set of pre-defined rules, methods, or operating procedures for eliminating plug flow. These strategies include: Adjusting flow rate: By changing the flow rate of a gas or liquid, the flow pattern can be changed from plug flow to other more stable flow patterns.

[0063] Changing the gas-liquid holdup: By adjusting the ratio of gas to liquid, the flow pattern changes.

[0064] Mechanical intervention: Breaking the plug flow by installing special piping devices such as mixers, energy dissipators, etc.

[0065] In this application, a specific gas is generated or adjusted based on a preset slug flow elimination strategy to help eliminate slug flow. Specific methods include: changing the flow pattern by increasing or decreasing the gas flow rate; and affecting the flow state of the fluid by changing the gas injection position or method.

[0066] In this embodiment, if the state of the gas-liquid two-phase fluid is detected as slug flow, a specific gas is generated or adjusted according to a pre-set slug flow elimination strategy to help eliminate the slug flow. This process typically involves adjusting the flow rate, temperature, composition, or injection method of the gas to change the flow pattern of the fluid.

[0067] The gas type of the target gas is the same as the gas type in the gas-liquid two-phase fluid, and the gas temperature of the target gas is the same as the gas temperature in the gas-liquid two-phase fluid.

[0068] It should be noted that the gas category refers to the type or composition of the gas. For example, the gas can be nitrogen ( ),oxygen( ),carbon dioxide( ) or any other specific gas.

[0069] Gas category in gas-liquid two-phase fluid: refers to the actual gas species present in the gas-liquid two-phase fluid. For example, in a gas-liquid two-phase fluid system, the gas can be air (mainly composed of nitrogen and oxygen) or a certain specific industrial gas.

[0070] For example, if the gas in the gas-liquid two-phase fluid is nitrogen, the target gas must also be nitrogen, not other gases. This consistency ensures the accuracy and comparability of experiments or operations.

[0071] Gas temperature in gas-liquid two-phase fluid refers to the actual temperature of the gas in the gas-liquid two-phase fluid.

[0072] For example, if the gas temperature in the gas-liquid two-phase fluid is 30°C, the temperature of the target gas must also be 30°C. This temperature consistency ensures the similarity of the gas in physical properties (such as density, viscosity, etc.), ensuring the accuracy and reliability of experiments or operations.

[0073] It can be understood that in a certain specific experiment, test or operation, the target gas not only must be completely consistent with the gas category in the gas-liquid two-phase fluid in terms of category, but also must be completely consistent with the gas temperature in the gas-liquid two-phase fluid in terms of temperature. This consistency ensures the accuracy and comparability of experiments or operations, avoiding errors or uncertainties caused by differences in gas category or temperature. In industrial processes, this condition can be used to ensure the stability and safety of production processes. For example, in oil and gas pipelines, if it is necessary to detect the gas composition and temperature in the pipeline, the category and temperature of the target gas must be consistent with the actual gas in the pipeline to ensure the accuracy of the detection results. In safety assessment, this condition can be used to ensure the accuracy and reliability of the assessment. For example, when assessing the safety of a gas-liquid two-phase fluid system, the category and temperature of the target gas must be consistent with the gas in the actual fluid to ensure the accuracy of the assessment results.

[0074] Specifically, the step of generating a target gas for eliminating the plug flow based on the preset plug flow elimination strategy further comprises steps S31-S32: Step S31, based on the preset strategy generation model, determine the target strategy for converting the state of the gas-liquid two-phase fluid from plug flow to slug flow or foam flow; It should be noted that the preset strategy generation model is a pre-designed model or algorithm for generating specific strategies.

[0075] It should be noted that slug flow (Slug Flow) is a flow pattern in which gas and liquid flow in alternating blocks. Its characteristics include: gas and liquid appear in alternating blocks; there may be significant pressure fluctuations during flow; usually occurs at moderate flow rates and gas-liquid phase fractions.

[0076] Annular flow is a flow pattern in which gas is dispersed in a liquid in the form of foam, forming an annular flow. Its characteristics include: the gas is dispersed in the liquid in the form of small bubbles; the flow is relatively stable with minimal pressure fluctuations; and it typically occurs at relatively low flow rates and low gas-liquid holdup.

[0077] The target strategy is a specific operation plan determined by the preset strategy generation model, which is used to transform the state of the gas-liquid two-phase fluid from plunger flow to block flow or foam flow.

[0078] In this application, a pre-defined strategy generation model is used to determine a specific strategy for transforming the gas-liquid two-phase flow from plug flow to slug flow or foam flow. This process involves adjusting fluid parameters (such as flow rate, gas-liquid holdup, and temperature) to achieve the desired flow pattern.

[0079] Step S32: determining a target gas for converting the state of the gas-liquid two-phase fluid from a plug flow to a block flow or a foam flow based on the target strategy and the target algorithm.

[0080] In this application, by combining a target strategy and a target algorithm, a specific gas (target gas) is identified that will help transform the state of the gas-liquid two-phase fluid from plug flow to slug flow or foam flow by adjusting its properties (such as flow rate, temperature, composition, etc.). This process involves the following steps: Step S40: introducing the target gas into the gas-liquid two-phase pipeline to eliminate the plunger flow.

[0081] Eliminating plug flow refers to converting plug flow into a more stable and efficient flow pattern through some method or measure. Plug flow may reduce fluid delivery efficiency and increase energy consumption.

[0082] Specifically, the steps for introducing the target gas into the gas-liquid two-phase pipeline to eliminate the plunger flow are as follows: First, a suitable injection location is selected, typically upstream or midway along the pipeline. The target gas is then introduced into the pipeline using a specialized injection device (such as a nozzle or mixer). Furthermore, sensors monitor the fluid conditions within the pipeline in real time to ensure effective target gas introduction. Finally, based on the monitoring results, the target gas's characteristics (such as flow rate, temperature, and composition) are dynamically adjusted to ensure slug flow is effectively eliminated.

[0083] The present application proposes a plunger flow elimination method and related equipment, which relate to the field of fluid mechanics technology. In the related technology, the plunger flow phenomenon often occurs in the pipeline. Plug flow is a special flow pattern in which gas and liquid advance alternately in a plunger shape. This flow pattern will cause pressure fluctuations and uneven flow rate in the pipeline. These fluctuations not only affect the stability of the low-temperature fractionation process, but may also cause equipment wear and increased energy consumption, thereby reducing the operating efficiency of the entire system. In comparison, in the present application, first, in response to the plunger flow detection instruction, the parameters of the gas-liquid two-phase fluid in the gas-liquid two-phase pipeline are obtained, and then, based on the parameters and the preset gas-liquid two-phase fluid state detection strategy, the state of the gas-liquid two-phase fluid is determined. Further, if the state is a plunger flow, based on the preset plunger flow elimination strategy, a target gas for eliminating the plunger flow is generated, and finally, the target gas is introduced into the gas-liquid two-phase pipeline to eliminate the plunger flow.

[0084] It can be understood that this application selects relevant formulas to calculate based on the type corresponding to the pipeline to determine whether there is a plunger flow. If so, based on the preset plunger flow elimination strategy, it determines the best method to convert the plunger flow into other flows. Based on the best method, the above formula is used to reversely deduce the gas required to destroy the plunger flow, and the gas is introduced into the plunger flow to destroy the plunger flow.

[0085] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 2 If the target flow pattern is the Mendheim flow pattern, the step of determining the state of the gas-liquid two-phase fluid based on the target algorithm and the parameters further includes steps A1 to A3: Step A1, calculating the liquid phase apparent flow rate and the gas phase apparent flow rate corresponding to the gas-liquid two-phase fluid based on the target algorithm and the parameters; It should be noted that the superficial velocity refers to the average velocity of one phase (gas or liquid) relative to the pipe wall in a gas-liquid two-phase flow. It takes into account the phase interactions and flow patterns of the fluid.

[0086] Based on the target algorithm and the actual measured parameters, the superficial flow rate of the liquid and gas phases is calculated. The specific steps are as follows: First, the measured fluid parameters (such as flow rate, gas-liquid holdup, pressure, and temperature) are input into the target algorithm. The target algorithm then performs calculations and analyses based on these input parameters. For example, the parameters can be substituted into a formula or model to calculate the superficial flow rates of the liquid and gas phases. Alternatively, the parameters can be input into a trained model to predict the superficial flow rates of the liquid and gas phases.

[0087] Step A2, determining a target region corresponding to the gas-liquid two-phase fluid in the Mendheim flow pattern based on the liquid phase apparent flow velocity and the gas phase apparent flow velocity; It should be noted that the Mendheim flow pattern diagram is a two-dimensional diagram used to classify the flow patterns of gas-liquid two-phase flow. The diagram usually includes the following flow patterns: Bubble Flow: Gas is dispersed in the liquid in the form of small bubbles.

[0088] Slug Flow: Gas and liquid appear alternately in larger lumps.

[0089] Annular Flow: Gas is dispersed in the liquid in the form of foam, forming annular flow.

[0090] Plug Flow: Gas and liquid advance in the form of a plunger (similar to piston motion).

[0091] The horizontal axis of a Mendheim flow pattern diagram typically represents the gas phase superficial velocity, while the vertical axis represents the liquid phase superficial velocity. Different regions correspond to different flow patterns.

[0092] The target area is a specific area in the Mendehan flow pattern diagram, determined by the liquid phase superficial velocity and the gas phase superficial velocity. Each area corresponds to a specific flow pattern. For example: Bubbly flow region: low gas velocity and low gas-liquid holdup.

[0093] Slug flow region: medium gas velocity, medium gas-liquid holdup.

[0094] Foam flow area: high gas phase velocity and high gas-liquid phase holdup.

[0095] Plug flow region: high gas velocity and low gas-liquid holdup.

[0096] In this embodiment, the position of the fluid on the Mendham flow pattern diagram is determined based on the calculated gas phase superficial velocity and gas-liquid holdup. The target region of the fluid is determined based on the position on the flow pattern diagram. For example, if the gas phase superficial velocity is low and the gas-liquid holdup is low, the fluid may be in the bubbly flow region; if the gas phase superficial velocity is medium and the gas-liquid holdup is medium, the fluid may be in the slug flow region; if the gas phase superficial velocity is high and the gas-liquid holdup is high, the fluid may be in the foamy flow region.

[0097] The specific embodiment is as follows. Assume that in a chemical plant, the actual measured parameters are as follows: The gas flow rate is 10 s, the liquid flow rate is 1 s, gas-liquid holdup ( ) is: gas accounts for 40%, pressure is 5MPa, temperature is 30°C, gas density is 1.2 , the liquid density is 1000 .

[0098] The apparent velocity calculated by the target algorithm is: the gas phase apparent velocity is 10m / s, the liquid phase apparent velocity is 1 s.

[0099] On the Mendehan flow diagram, according to the gas phase apparent velocity (10 s) and the liquid superficial velocity is (1 s), determine the target area where the fluid is located. Assume that the flow pattern is as follows: Bubble flow region: gas phase velocity <5 s, liquid phase flow rate <0.5 s.

[0100] Block flow area: 5 s≤gas phase velocity≤15 s, 0.5m / s≤Liquid phase velocity≤1.5 s.

[0101] Foam flow area: gas phase velocity>15 s, liquid phase flow rate>1.5 s.

[0102] According to the above parameters, the gas phase flow rate is 10 s, liquid phase flow rate is 1 s, the fluid is in the bulk flow region.

[0103] Step A3: determining the state of the gas-liquid two-phase fluid based on the target area.

[0104] In this application, the specific flow pattern of the gas-liquid two-phase fluid is determined based on the target area. For example, if the target area is a bubbly flow area, the fluid state is bubbly flow; if the target area is a slug flow area, the fluid state is slug flow; if the target area is a foam flow area, the fluid state is foam flow; if the target area is a plug flow area, the fluid state is plug flow.

[0105] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the first and second embodiments can be referred to above and will not be described in detail. Figure 3 Before the step of generating a model based on a preset strategy, steps B1 to B4 are also included: Step B1, obtaining sample data, wherein the strategy corresponding to the sample data is the first strategy; Sample data refers to the data used for model training. Sample data can include various measurements, parameters, or observations, depending on the application scenario.

[0106] The first strategy refers to the true labels corresponding to the sample data.

[0107] Step B2, using the current strategy generation model to process the sample data to generate a second strategy; Current Strategy Generation Model: This is a pre-set model or algorithm used to generate strategies based on input sample data. The model can be based on empirical formulas, machine learning algorithms, or other rule engines.

[0108] In this embodiment, the sample data obtained in step B1 is input into the current strategy generation model to obtain the second strategy.

[0109] Step B3, determining whether the first strategy is consistent with the second strategy; Step B4: If there is inconsistency, modify the parameters of the current policy generation model, and based on the modified current policy generation model, return to the step of processing the sample data using the current policy generation model until the first policy is consistent with the second policy to obtain the preset policy generation model.

[0110] It should be noted that if the first and second policies are inconsistent, the current policy generation model needs to be adjusted. Based on the consistency check results, the parameters of the policy generation model are adjusted. Parameter adjustment can be based on an optimization algorithm (such as gradient descent, genetic algorithm, etc.) or manual adjustment. Using the adjusted policy generation model, the sample data obtained in step B1 is reprocessed. This is an iterative process, repeating steps B2 through B4 until the first and second policies are consistent. Once the first and second policies are consistent, the current policy generation model is considered the default policy generation model.

[0111] In this application, the model is iteratively trained according to the scenario, which can improve adaptability and accuracy, enhance generalization ability, optimize performance, adapt to dynamically changing environments, improve interpretability and transparency, reduce complexity and overfitting risks, support multi-objective optimization, improve scalability, support online learning and real-time updates, and reduce development and maintenance costs.
