[0001] This application relates to the field of coking technology, and in particular to a method and related equipment for identifying the capacity of a benzene elution process. Background Technology

[0002] Currently, the production capacity evaluation standard for benzene washing operations in coal gas relies on the detection of benzene content before and after the coal gas process. However, this identification method typically only detects changes in benzene content at the beginning and end of the washing process, resulting in long detection times and limited data. With the increasing intelligence in the coking industry, the lack of real-time data and the extremely limited benzene detection data make it difficult to provide a real-time evaluation of the entire benzene washing system. Summary of the Invention

[0017] If the index change value is greater than or equal to a first preset multiple of the preset crude benzene content of the gas to be cleaned, the corresponding index change value is removed; and / or,

[0018] If the index change value is less than or equal to a second preset multiple of the preset crude benzene content of the gas to be cleaned, the corresponding index change value is removed.

[0019] In some embodiments, the method for identifying the ability of the benzene elution process further includes:

[0020] In the case where there are multiple consecutive index change values ​​that are greater than or equal to a first preset multiple of the preset crude benzene content of the gas to be cleaned, the minimum multiple relationship between the corresponding index change value and the preset crude benzene content of the gas to be cleaned is determined.

[0021] The actual crude benzene content of the gas to be cleaned is determined based on the minimum multiple relationship.

[0022] In some embodiments, the step of converting the benzene delivery flow rate for each of the fixed time periods into a benzene delivery level value includes:

[0023] The flow rate-to-level conversion index is determined based on the geometric characteristics of the benzene storage tank.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0038] The first aspect of this application provides a method for identifying the ability of a benzene elution process. Figure 1 This is a schematic flowchart illustrating the capability identification method for benzene elution. (See also...) Figure 1 Including: S110-S130.

[0039] S110: Obtain the effective material level values ​​for multiple fixed time periods.

[0040] For example, fixed time periods can be statistically analyzed in different ways depending on production needs, such as 1 second, 30 minutes, or 1 hour. Multiple fixed time periods can be continuous or discontinuous, and the total duration can be determined based on production requirements. The aforementioned effective level value represents the cumulative level change over a fixed time period. This cumulative level change reflects the coupling value of the levels of crude benzene injected into and discharged from the benzene storage tank within that fixed time period. The injected benzene storage tank level is positive, and the discharged benzene storage tank level is negative. The aforementioned effective level value can be obtained using a level gauge installed within the benzene storage tank.

[0041] S120 converts the benzene delivery flow rate for each fixed time period into the benzene delivery level value.

[0042] For example, the flow rate of crude benzene discharged from the benzene storage tank at each fixed time interval can be obtained using detection devices such as flow meters. The detected benzene outflow flow rate for each fixed time interval can be converted into a benzene outflow level value based on the density of the discharged crude benzene and the structure of the benzene storage tank. It is easy to understand that since the frequency and duration of benzene discharge from the benzene storage tank are uncertain, if no crude benzene is discharged during a certain fixed time interval, the benzene outflow flow rate during that fixed time interval will be zero.

[0043] S130 determines the system output index for each fixed time period based on the effective value of the material level and the benzene external material level.

[0044] For example, the system production index described above is used to represent the total amount of crude benzene injected into the benzene storage tank in each fixed time period. The system production index for each fixed time period can be calculated using the following formula:

[0045] S = L d +L (1)

[0046] Where S represents the system output index for each fixed time period, and L d This represents the benzene delivery level for each fixed time period, where L represents the effective level value for each fixed time period.

[0047] Understandably, currently, the change in benzene content in the gas is typically measured at the beginning and end of the entire benzene washing process to obtain the crude benzene production, resulting in insufficient data. Furthermore, during the entire benzene washing process, because crude benzene is continuously injected into the benzene storage tank and periodically discharged, if crude benzene is discharged during a certain fixed time period, the level gauge in the benzene storage tank can only reflect the coupled value of the injected and discharged crude benzene, and cannot independently determine the injected amount. This application obtains the benzene external flow rate value for the aforementioned fixed time period and converts this value into a benzene external material level value based on the structure of the benzene storage tank. This benzene external material level value reflects the change in crude benzene discharged during the fixed time period, with the material level as a reference. Therefore, based on the benzene external material level value and the effective material level value, the system production index for each fixed time period can be obtained, i.e., the amount of crude benzene injected into the benzene storage tank. Then, based on the system production index for multiple fixed time periods, the production capacity level in the benzene washing process can be determined in real time.

[0048] According to some embodiments, the above-mentioned method for identifying the capacity of the benzene elution process further includes: determining the equipment operating status based on the change range of the system output index for each fixed time period.

[0049] For example, the time intervals for each fixed period are the same, the gas injection rate and the operating status of the benzene removal tower cleaning equipment are stable, and the density of crude benzene in the gas remains essentially unchanged. Therefore, the variation range of the system output index in each fixed period should not fluctuate significantly. By acquiring the system output index for multiple fixed periods, the discrete points that appear during these periods can be analyzed. If the discrete points are few and scattered, it may indicate occasional equipment instability or problems with the detection data, requiring judgment based on the actual situation. On the other hand, the changing trend of the system output index can be analyzed. If the system output index shows a continuous downward trend, there is a possibility of a decrease in the cleaning capacity of the cleaning equipment. Therefore, based on the effective value of the material level and the benzene external flow rate obtained by the detection equipment, the operating status of the cleaning equipment can be quickly predicted, improving the reliability of safe and stable production and avoiding raw material waste.

[0050] According to some embodiments, the step of determining the equipment operating status based on the change range of the system output index for each fixed time period includes: determining the difference between the system output index of two adjacent fixed time periods as the index change value; and determining the equipment operating status based on the index change value.

[0051] For example, the difference between the system production index of two adjacent fixed time periods can be determined as the index change value. This index change value represents the change in the system production index between two adjacent fixed time periods, which reflects the change in the amount of crude benzene injected into the benzene storage tank between those two periods. The index change value can be calculated using the following formula:

[0052] ΔS=S t1 —S t0 (2)

[0053] Where ΔS represents the exponential change value, S t1 S represents the system output index for a fixed time period t1. t0 The system output index represents the output over a fixed time period t0, and t1 represents the system output index over a fixed time period. <t0。

[0054] It is understandable that the above-mentioned index change values ​​are obtained based on the system output index of two adjacent fixed time periods. Since the change range of the system output index is usually not large, and the order of magnitude of the system output index is typically in the tens of thousands, it is difficult for operators to intuitively obtain the equipment operating status from the changes in the system output index over multiple fixed time periods. By subtracting adjacent system output indices to obtain the index change value, the change range between multiple above-mentioned index change values ​​is larger. Therefore, the benzene elution process capability identification method provided in this application embodiment can more accurately and intuitively obtain the change range of the amount of crude benzene injected into the benzene storage tank, thereby improving the accuracy and timeliness of predicting the operating status of the cleaning equipment.

[0055] According to some embodiments, the above-mentioned benzene washing process capability identification method further includes: obtaining the preset crude benzene content of the gas to be washed; and determining the equipment operating status based on the comparison relationship between the exponential change value and the preset crude benzene content of the gas to be washed.

[0056] For example, the crude benzene content in the gas to be cleaned can be set to a preset value. This preset value is then compared with each of the aforementioned index changes. If the difference is too large, it indicates either a problem with the operating status of the benzene removal tower or an error in the collected data. The preset crude benzene content can be determined using the following formula:

[0057] Q t =Q m *K (3)

[0058] Among them, Q t Q represents the preset crude benzene content of the gas to be cleaned. m This represents the amount of gas to be cleaned in each fixed time period, and K represents the preset percentage of crude benzene content in the gas to be cleaned.

[0059] It should be noted that the crude benzene content in the gas to be cleaned is usually within a certain range, such as 25 to 35 g / m³. 3 Even after benzene removal, a certain amount of crude benzene will remain in the gas to be cleaned, such as 2 to 4 g / m³. 3 The preset crude benzene content can be slightly higher than the typical range for crude benzene content in the cleaned gas. It can be determined based on the sum of the crude benzene content before and after cleaning, such as 40 g / m³. 3 The preset crude benzene content is determined based on the sum of the crude benzene content before and after cleaning. This preset crude benzene content is equivalent to a theoretically calculated maximum value. If the above-mentioned exponential change value exceeds the theoretical maximum value, it indicates that the probability of errors in the collected data is greater.

[0060] According to some embodiments, the above-mentioned benzene washing process capability identification method further includes: removing the corresponding index change value when the index change value is greater than or equal to a first preset multiple of the preset crude benzene content of the gas to be washed; and / or removing the corresponding index change value when the index change value is less than or equal to a second preset multiple of the preset crude benzene content of the gas to be washed.

[0061] For example, when the exponential change value is greater than or equal to a first preset multiple of the preset crude benzene content of the gas to be cleaned, as shown in the following formula:

[0062] ΔS≥P1*Q tm (4)

[0063] Where P1 represents the first preset multiple, P1 is greater than zero, Q tm This indicates the material level value corresponding to the preset crude benzene content of the gas to be cleaned for each fixed time period.

[0064] It is understandable that the aforementioned first preset multiple can be set with reference to the commonly used tension coefficient and design redundancy value of coke ovens, taking into account the redundancy values ​​between different systems. It is determined by the product of the tension coefficient, the design redundancy value, and the redundancy value between different systems. For example, if the commonly used tension coefficient of a coke oven is 1.07, the design redundancy value is 1.2, and the redundancy value between systems is 1.2, then the aforementioned first preset multiple is 1.5. Since the probability of daily values ​​exceeding the aforementioned redundancy value is very small, the most likely source of numerical error in this case is measurement error, i.e., detection data such as level gauges and flow statistics devices. Therefore, if the aforementioned index change value exceeds the first preset multiple of the preset crude benzene content of the gas to be cleaned within a certain fixed time period, from the perspective of material balance, it has exceeded the theoretical calculation value. The corresponding index change value needs to be removed to ensure the accuracy of the obtained data and improve the accuracy of predicting the operating status of the cleaning equipment.

[0065] When the exponential change value is less than or equal to a second preset multiple of the preset crude benzene content of the gas to be cleaned, as shown in the following formula:

[0066] ΔS≤P2*Q tm (5)

[0067] Wherein, P2 represents the second preset multiple, and P2 is less than zero.

[0068] It is understandable that the aforementioned index change values ​​represent the change in the system output index between two adjacent fixed time periods. Therefore, negative values ​​are possible, especially when the change exceeds a second preset multiple of the preset crude benzene content. This indicates that the equipment operation in the previous stage had malfunctioned, leading to severe underproduction. Therefore, the corresponding index change values ​​need to be removed to ensure the accuracy of the acquired data and improve the accuracy of predicting the operating status of the cleaning equipment. The selection of the second preset coefficient can be determined based on the length of the fixed time interval, such as -0.2.

[0069] According to some embodiments, the above-mentioned benzene washing process capability identification method further includes: when there are multiple consecutive exponential change values ​​that are greater than or equal to a first preset multiple of the preset crude benzene content of the gas to be washed, determining the minimum multiple relationship between the corresponding exponential change value and the preset crude benzene content of the gas to be washed; and determining the actual crude benzene content of the gas to be washed based on the minimum multiple relationship.

[0070] For example, if multiple consecutive index change values ​​are greater than or equal to a first preset multiple of the preset crude benzene content of the gas to be cleaned, it indicates that the preset crude benzene content of the gas to be cleaned is set too low, and the crude benzene content in the gas is higher than usual. The minimum multiple relationship between multiple consecutive index change values ​​and the preset crude benzene content of the gas to be cleaned can be selected, and the actual crude benzene content of the gas to be cleaned can be determined based on this minimum multiple relationship.

[0071] Understandably, using the smallest multiple relationship to determine the actual crude benzene content can reduce errors.

[0072] According to some embodiments, the step of converting the benzene delivery flow rate for each fixed time period into a benzene delivery level value includes: determining a flow rate-to-level conversion index based on the geometric characteristics of the benzene storage tank; and converting the benzene delivery flow rate for each fixed time period into a benzene delivery level value based on the flow rate-to-level conversion index.

[0073] For example, the geometric characteristics of benzene storage tanks vary considerably depending on their structure. Benzene storage tanks are generally square, cylindrical (vertical, horizontal), or spherical (typically pressure vessels). Therefore, converting the discharge flow rate of crude benzene from the storage tank into the benzene storage tank level value is related to the geometric characteristics of the storage tank. It is easy to understand that once the structure of the benzene storage tank is determined, the conversion relationship between the benzene delivery flow rate and the benzene delivery level value is determined. Therefore, the flow-to-level conversion index can be determined based on the geometric characteristics of the benzene storage tank, such as through the following formula:

[0074]

[0075] Where Z represents the traffic conversion index, Q b This represents the crude benzene flow rate for each fixed time period. It should be noted that Q... b Z can represent the mass of crude benzene emissions in each fixed time period, and is a unit of mass per unit time. Correspondingly, the unit of Z is the ratio of mass to length.

[0076] Understandably, when the benzene storage tank is square or a vertically placed cylinder, the value of Z is related to the bottom area of ​​the storage tank. However, when the benzene storage tank is spherical, the value of Z is related to the current material level in the tank, and the aforementioned flow conversion index is determined based on this current material level. By setting the flow conversion index, the conversion efficiency between flow rate and material level can be improved.

[0077] Based on the above flow conversion index, the amount of gas to be cleaned at each fixed time interval can also be converted into the material level value corresponding to the preset crude benzene content of the gas to be cleaned at each fixed time interval, which can be calculated using the following formula:

[0078]

[0079] Among them, Q tm As expressed in formulas (4) and (5), Q m The meaning is the same as in formula (3). Combining formula (3) and formula (7), the unit and value of K can be determined, such as when the crude benzene content in the gas to be cleaned is 40 g / m³. 3 In this case, K can be 0.00004 (t / m 3 ).

[0080] To better understand this application, a specific example of the benzene elution process capability identification method provided in this application is given:

The corresponding vertical axis points represent the system output index and the index change value. The same applies to subsequent points, so I will not repeat them here.

[0086] according to Figure 2 The curves showing the changes in the medium index and the system output index can reflect the real-time changes in the amount of crude benzene removed from the gas to be cleaned in the entire benzene washing process. This allows for the prediction of the operating status of equipment or potential faults in the detection equipment during the benzene washing process.

[0087] The above describes the method for identifying the ability of the benzene elution process. The following describes the benzene elution process ability identification device in the embodiments of this application.

[0088] Please see Figure 3 One embodiment of the benzene elution process capability identification device described in this application may include:

[0089] The acquisition module 301 is used to acquire the effective values ​​of material level over multiple fixed time periods. The effective values ​​of material level are used to represent the cumulative amount of material level change over a fixed time period.

[0090] The conversion module 302 is used to convert the benzene delivery flow rate for each fixed time period into the benzene delivery level value;

[0091] The determination module 303 is used to determine the system output index for each fixed time period based on the effective value of the material level and the benzene external material level.

[0092] According to the benzene elution process capacity identification device provided in the above embodiment, by acquiring the benzene outflow rate value for the above fixed time period, and converting the benzene outflow rate value into a benzene outflow level value based on the structure of the benzene storage tank, the benzene outflow level value is used to reflect the change value of crude benzene discharged in the fixed time period with reference to the level. Thus, the system output index for each fixed time period can be obtained based on the benzene outflow level value and the effective level value, that is, the injection amount of crude benzene into the benzene storage tank. Then, the production capacity level in the benzene elution process can be determined in real time based on the system output index of multiple fixed time periods.
