[0050] Figure 1 A flow chart of a reactor control method 100 according to an embodiment of the present disclosure is shown. The method 100 may include:

[0051] Step 110, determining the current working stage of the reactor;

[0052] The current working stage can be a load lifting stage or a normal reaction stage, wherein the feed flow rate in the load lifting stage shows an upward trend, the feed flow rate in the load reducing stage shows a downward trend, and the feed flow rate in the normal reaction stage remains basically unchanged and is in a stable stage.

[0053] Step 120, obtaining the current conversion rate of the reactor;

[0054] Current conversion rate Among them, the AIC monitoring value is the measured component in the reactor, which is used to characterize the ratio of the main material A to all materials in the reactor. is the initial concentration of reaction material A (main material).

[0055] Step 130: determining a calculation result corresponding to the current conversion rate according to the current working stage, wherein the calculation result includes at least one of a temperature setting value of the reactor, a residence time of the reactor, and a feed flow rate of the reactor;

[0056] Step 140: Control the reactor according to the calculation result corresponding to the current conversion rate.

[0057] By determining the current working stage of the reactor and the current conversion rate of the reactor, the calculation result corresponding to the current conversion rate in the current working stage can be determined. Then, based on the calculation result corresponding to the current conversion rate, the reactor is automatically controlled. Thus, in different working stages of the reactor, the reactor temperature, residence time and feed flow rate are used to effectively control the reactor. In this way, it can be ensured that the reactor has a good conversion rate and that the reactor can operate safely and smoothly to avoid the risk of overtemperature and overpressure.

[0058] In some embodiments, determining a calculation result corresponding to the current conversion rate according to the current working stage includes:

[0059] If the current working stage is a load lifting stage, obtaining at least one parameter of the initial temperature of the reactor, the feed flow rate of the reactor, the feed specific heat capacity of the reactor, the reaction enthalpy value of the reactor, the initial concentration of the feed, the diameter of the reactor, and the real-time liquid level of the reactor;

[0060] Calculating a first preliminary set temperature of the reactor according to the at least one parameter and the current conversion rate;

[0061] The calculation method of the first preliminary set temperature T is as follows:

[0062] (Set temperature calculation formula), where,

[0063] T: first preliminary set temperature, k;

[0064] T0: initial reaction temperature, k;

[0065] F1: Feed flow rate of reaction material A, m 3 / h;

[0066] F2: Feed flow rate of reaction material B, m 3 / h; material A and material B are fed.

[0067] C p : Specific heat capacity of the reaction materials (average specific heat capacity of material A and material B), KJ / (kg.k);

[0068] ΔH: reaction enthalpy, KJ / mol;

[0069] Initial concentration of reaction material A, mol / m 3 ;

[0070] X: reaction conversion rate, %;

[0071] D: diameter of the reactor, m;

[0072] L1: Real-time liquid level of the reactor, m;

[0073] Feed composition F1: F = x;

[0074] m is the sum of the masses of material A and material B.

[0075] The first preliminary set temperature is compared with the current measured temperature of the reactor to determine the temperature set value of the reactor. The current measured temperature of the reactor is the temperature of the reactor measured by the temperature controller TICA1.

[0076] By comparing the first preliminary set temperature with the current measured temperature of the reactor, the higher one of the first preliminary set temperature and the current measured temperature can be selected as the temperature setting value of the reactor. In this way, a high temperature setting value can be selected to control the reactor. In this way, the reactor can be effectively controlled by increasing the cooling water, adjusting the residence time of the reactor, reducing the flow rate of the material, etc.

[0077] In some embodiments, determining a calculation result corresponding to the current conversion rate according to the current working stage includes:

[0078] If the current working stage is a normal working stage, obtaining the current measured temperature of the reactor;

[0079] If the current measured temperature is within a first preset temperature range, the second preliminary set temperature of the reactor is calculated using the components in the reactor; the minimum value in the first preset temperature range is greater than the normal allowable temperature of the reactor.

[0080] The second preliminary set temperature may be calculated as follows:

[0081] The conversion rate of the reactor is calculated using the components in the reactor, and the set temperature of the second device can be calculated by substituting the conversion rate into the above set temperature calculation formula.

[0082] The higher of the second preliminary set temperature and the current measured temperature is used as the temperature setting value of the reactor;

[0083] The controlling of the reactor according to the calculation result corresponding to the current conversion rate includes:

[0084] The temperature setting value is used to control the flow rate of the circulating cooling water of the reactor.

[0085] After the second preliminary set temperature of the reactor is calculated using the components in the reactor, the higher temperature between the second preliminary set temperature and the current measured temperature can be used as the temperature setting value of the reactor, that is, the higher temperature between the two can be used as the temperature setting value of the reactor, so as to use the high temperature to control the flow rate of the circulating cooling water of the reactor. In this way, when the temperature of the reactor is high, the flow rate of the circulating cooling water can be increased.

[0086] In some embodiments, determining a calculation result corresponding to the current conversion rate according to the current working stage includes:

[0087] If the current working stage is a normal working stage, obtaining the current measured temperature of the reactor;

[0088] If the current measured temperature is within the second preset temperature range, the residence time of the reactor is calculated using the current conversion rate. The minimum value in the first preset temperature range is greater than the normal allowable temperature of the reactor, and the maximum value in the first preset temperature range is less than or equal to the minimum value in the second preset temperature range.

[0089] If the current working stage is a normal working stage and the current measured temperature is within the second preset temperature range, it means that the temperature of the reactor can no longer be lowered by increasing the cooling water, and the current measured temperature of the reactor has continued to rise. Therefore, the residence time of the reactor can be calculated using the current conversion rate, thereby adjusting the residence time of the reactor to effectively control the reactor.

[0090] Of course, in this embodiment, the second preliminary set temperature of the reactor can also be calculated using the components in the reactor, and then the higher temperature between the second preliminary set temperature and the current measured temperature is used as the temperature setting value of the reactor, that is, the higher temperature between the second preliminary set temperature and the current measured temperature is selected as the temperature setting value.

[0091] In some embodiments, calculating the residence time of the reactor using the current conversion rate includes:

[0092] The residence time of the reactor is calculated using a first preset formula and the current conversion rate, wherein the first preset formula is:

[0093]

[0094] Wherein, X is the current conversion rate, is the initial concentration of the main material in the feed, A is the frequency factor, E is the activation energy, R is the molar gas constant and n is the reaction order.

[0095] By using the above first preset formula, the residence time of the reactor can be accurately calculated.

[0096] In some embodiments, determining a calculation result corresponding to the current conversion rate according to the current working stage includes:

[0097] If the current working stage is a normal working stage, determining the current measured temperature of the reactor;

[0098] If the current measured temperature is within the third preset temperature range, the feed flow rate of the reactor is calculated using the current conversion rate. The maximum value in the second preset temperature range is less than or equal to the minimum value in the third preset temperature range.

[0099] If the current working stage is a normal working stage and the current measured temperature is within the third preset temperature range, it means that the temperature of the reactor can no longer be lowered by increasing the cooling water and adjusting the residence time of the reactor, and the current measured temperature of the reactor has continued to rise. Therefore, the current conversion rate can be used to calculate the feed flow rate of the reactor, thereby reducing the feed flow rate to effectively control the reactor.

[0100] In some embodiments, the calculating the feed flow rate of the reactor using the current conversion rate includes:

[0101] The feed flow rate of the reactor is calculated using a second preset formula and the current conversion rate, wherein the second preset formula is:

[0102]

[0103] Wherein, F=F1+F2, F1 and F2 are different feed flow rates of the reactor, X is the current conversion rate, D is the diameter of the reactor, L1 is the real-time liquid level of the reactor, is the initial concentration of the main feed in the feed, E is the activation energy, R is the molar gas constant, and T is the second preliminary set temperature of the reactor.

[0104] By using the second preset formula, the feed flow rate of the reactor can be accurately calculated.

[0105] The following will be combined Figure 2 Further details of the technical solution of the present disclosure (wherein, Figure 2 In the diagram, FIC1-FIC4 are flow meters; FFIC is a proportional controller used to control the ratio between feeds; W1 and W2 are calculation modules; TICA1 is a temperature controller used to control and detect the temperature of the reactor; AIC is a component detection controller in the reactor; and LIC is a liquid level detection controller).

[0106] 1. Reactor temperature control scheme during load lifting and lowering stages

[0107] In the load-raising stage of the continuous two-phase reaction, the load is increased by controlling the feed flow rate. TICA1 monitors the reactor temperature in real time. When the temperature deviates, FIC3 is promptly controlled to adjust the reactor cooling water flow rate. Specifically, W1 calculates the heat transfer required for the reaction (i.e., T in formula (1)) by the feed flow rate FT1, and selects the current measured value of TICA1. The higher temperature is used as the set value of TICA1 (i.e., the temperature set value). The calculation formula is as follows:

[0108]

[0109] in:

[0110] T: reactor temperature, k;

[0111] T0: initial reaction temperature, k;

[0112] F1: Feed flow rate of reaction material A, m 3 / h;

[0113] F2: Feed flow rate of reaction material B, m 3 / h;

[0114] C p : Specific heat capacity of the reaction materials (average specific heat capacity of material A and material B), KJ / (kg.k);

[0115] ΔH: reaction enthalpy, KJ / mol;

[0116] Initial concentration of reaction material A, mol / m 3 ;

[0117] X: reaction conversion rate, %;

[0118] D: diameter of the reactor, m;

[0119] L1: Real-time liquid level of the reactor, m;

[0120] Feed composition F1: F = x

[0121] Conversion rate Among them, the AIC monitoring value is used to characterize the ratio of the main material A to all materials in the reactor. The main material is the feed with the greatest impact on the conversion rate among all feeds.

[0122] 2. Reactor temperature control scheme during normal operation

[0123] During the normal production stability stage, the reactor conversion rate can be maintained within the optimal range by controlling the feed flow ratio, the reactor temperature cascade cooling water flow rate, and the liquid level control residence time.

[0124] However, if the above parameters deviate significantly during normal operation, the following solution can be used to control the reaction temperature in a stable state:

[0125] The reactor is set up with three temperature control modes: T1~T2, T2~T3, and T3~T4. When the temperature is within the range of T1~T2, the reactor heat transfer calculated by the measured AIC and the current measured temperature of TICA1 are selected, and the high temperature of the two, that is, the high reactor heat transfer, is used to adjust the reactor cooling water feed to maintain the reactor temperature; when the temperature is within the range of T2~T3, the reactor residence time LT is adjusted to ensure that the reaction conversion rate is within the optimized range; when the temperature is within the range of T3~T4, the reactor feed is controlled to reduce the reaction heat by reducing the feed amount to ensure that the reactor temperature is within a safe range. In addition, when the current measured temperature of the reactor is within the range of T1~T2, T2~T3, and T3~T4, it can be as follows Figure 3 As shown, an alarm is issued. The higher the current measured temperature, the higher the alarm level. The current measured temperature is lower than T1, which is the normal allowable temperature of the reactor and no alarm is issued.

[0126] The relationship between the reactor temperature and the conversion rate is shown in formula (1); the relationship between the reactor residence time and the conversion rate is shown in formula (2):

[0127]

[0128] in:

[0129] t: reactor residence time, h;

[0130] The relationship between the reactor feed flow rate and conversion rate is shown in formula (3):

[0131]

[0132] Where: F = F1 + F2

[0133] Feed composition F1: F=x.

[0134] The specific implementation method is as follows

[0135] a. T1-T2 stage

[0136] When the current temperature of the reactor is within the temperature range of T1 to T2, the reactor heat transfer calculated by the measured AIC (i.e., the conversion rate is calculated by the components measured by AIC, and then the conversion rate is substituted into Formula 1 to calculate the required heat transfer T) is compared with the current measured temperature of TICA1. The higher temperature, i.e., the higher reactor heat transfer rate, is used to adjust the reactor cooling water flow rate, thereby adjusting the reactor temperature. There is a corresponding relationship between temperature and cooling water flow rate, which can be used to adjust the cooling water flow rate.

[0137] b.T2-T3 stage

[0138] When the current temperature of the reactor is within the temperature range of T2 to T3, the residence time of the reactor is calculated by the conversion rate, and the reactor liquid level control loop is overridden.

[0139] c.T3-T4 stage

[0140] When the current temperature of the reactor is within the temperature range of T2 to T3, the reaction temperature is already higher than the optimal temperature operating range. At this time, the measured conversion rate is used to calculate the reactor feed flow rate, reduce the feed amount, and reduce the load.

[0141] The present disclosure is explained by taking a certain supercritical polymerization reaction as an example.

[0142] A continuous two-phase reactor has an operating pressure of 0.2 MPaG, a design pressure of 1 MPaG, an operating temperature of 100°C, a design temperature of 250°C, a preheating temperature of 50°C, and a volume of 20m 3 The reactor diameter is 4m, the feed ratio of F1 and F2 is 2:1, and the initial concentration of the reaction material A is The reaction is a second-order reaction related to raw material A, with a reaction frequency factor A = 3, an activation energy E = 5, a universal gas constant R = 8.314 J / (kg.k), a reaction enthalpy ΔH = 5250 KJ / mol, and a specific heat capacity C of the reaction material. p =1KJ / (kg.k), the mass of the material in the reactor under normal operating conditions is m=500kg. According to laboratory simulation, the reaction feed F1 in the normal reaction stage is 272m 3 / h, F2=136m 3 / h, the normal reaction residence time is about 9.5h, the conversion rate in the normal reaction stage is maintained at 95%, the reactor liquid level is maintained at 60%, and the reactor height is 3m.

[0143] 1. Reactor temperature control scheme during load lifting and lowering stages

[0144] The operating temperature of the reactor is 100℃. During the load increase stage, the reactor temperature needs to be raised from 50℃ to 100℃ by feeding. According to W1 calculation, when the feed flow rate F1+F2 is increased to 408m 3 / h, the reactor temperature rises from 50°C to the reaction temperature of 100°C. During this heating process, if the temperature increases at a constant rate, the reactor temperature control loop TT1 is triggered, adjusting the cooling water flow rate within a small range to achieve the purpose of controlling the reactor temperature. During the load increase phase, if the flow rate increases too quickly and the temperature calculated by the WI calculation module exceeds the current measured temperature of TICA1, the override control is triggered, and the WI controls the cooling water feed of FIC3 to preemptively adjust the temperature increase caused by the increased feed.

[0145] 2. Reactor temperature control scheme during normal operation

[0146] In the stable production stage, the reaction temperature is 100°C. Based on the experimental and operation results, T1 = 105°C, T2 = 115°C, T3 = 120°C, and T4 = 125°C are selected.

[0147] 1) In the T1-T2 stage

[0148] When the reactor temperature rises due to abnormal operating conditions, W2 compares the reactor heat transfer amount calculated by the measured AIC (i.e., the conversion rate is calculated by the components measured by AIC, and then the conversion rate is substituted into Formula 1 to calculate the required heat transfer T) with the current measured temperature of TICA1. The higher one is selected and the higher reactor heat transfer amount is used to increase the reactor cooling water flow. When the reactor temperature returns to the normal operating range of 100°C, the override control is released.

[0149] 2) In the T2-T3 stage

[0150] When the cooling medium flow rate is still not able to effectively reduce the temperature, the reactor temperature enters the T2-T3 (115-120°C) stage, triggering W2 (Formula 2) to override the reactor residence time to adjust the reactor temperature.

[0151] 3) In the T3-T4 stage

[0152] In the temperature stage of T3~T4 (120~125℃), after the reactor temperature cannot be effectively reduced after adjusting the cooling medium flow rate and residence time, the reactor temperature enters the T3~T4 stage. The reactor feed flow rate is calculated using the measured conversion rate, and the reactor feed is gradually reduced until the temperature drops to an acceptable range.
