Description

Technical Field

[0001] The present invention relates to the technical field of fuel oil blending, and in particular to a fuel oil blending method, device, equipment and storage medium. Background Art

[0002] Marine fuel oil production is an important part of the petroleum refining industry. After crude oil is refined, light oil (gasoline, diesel, aviation kerosene, etc.) products are separated, and a large part of the remaining heavy components are used for the production of marine fuel products. However, the heavy components obtained after crude oil refining are difficult to be directly used as fuel oil products for ships. It is also necessary to blend the heavy components and some light components (diesel, etc.) so that the properties of the mixture meet the national standards for marine fuel oil.

[0003] At present, the blending of marine fuel oil in refineries is generally done by empirical blending, using empirical formulas obtained after a large number of laboratory tests. However, when blending fuel oil, since the viscosity properties of marine fuel oil belong to nonlinear mixing properties, the existing linear viscosity calculation model cannot be used to describe and predict the viscosity value of the mixed fuel oil. After each blending, the blended finished oil must be subjected to national standard quality testing experiments to verify whether the blended finished oil can be used to produce qualified products, which makes the blending test cycle of fuel oil longer.

[0004] In addition, the types of oil used to blend marine fuel oil often change, and the properties of each oil type are unstable. When the component oil types and properties of the component oils change, the empirical formula will become invalid. Once the empirical formula becomes invalid, the qualified rate of the blended product will be greatly reduced, and the number of national standard quality inspection experiments will increase accordingly. It is necessary to adjust the formula many times and conduct multiple national standard quality inspection experiments after blending, which will lead to excessive use of high-cost component oils, wasting a lot of manpower, material resources and time costs. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figure 1 , is a flow chart of a fuel oil blending method provided by an embodiment of the present invention, comprising the following specific steps:

[0042] S1. Obtaining a blending formula of fuel oil; wherein the blending formula includes: the names of the component oils used for blending, and the blending mass ratio of the component oils;

[0043] (1) Before blending the fuel oil, first obtain the blending formula of the fuel oil, detect the blending formula of the fuel oil, and predict whether the viscosity of the mixed fuel oil blended according to the blending formula meets the quality standard; the blending formula includes: the component oil names of the component oils used for blending, and the blending mass ratio of the component oils.

[0044] S2. Obtaining a first viscosity value of each component oil at a first temperature according to the component oil name;

[0045] Preferably, the generation of the first viscosity value includes: for each component oil, obtaining first viscosity data of a viscometer of the component oil at the first temperature, and determining whether the first viscosity data exceeds the measuring range of the viscometer; when the first viscosity data does not exceed the measuring range of the viscometer, storing the first viscosity data as the first viscosity value of the component oil.

[0046] Preferably, the method further includes: when the first viscosity data exceeds the measuring range of the viscometer, obtaining second viscosity data of the viscometer of the component oil at several second temperatures; wherein the second temperature is higher than the first temperature; when the second viscosity data does not exceed the measuring range of the viscometer, generating a viscosity curve of the component oil at each of the second temperatures according to the second viscosity data; and calculating the viscosity value of the component oil at the first temperature according to the viscosity curve, and storing the viscosity value as the first viscosity value of the component oil.

[0047] (2) After knowing the names of the component oils used for blending, the first viscosity value of each component oil at a preset first temperature can be measured by a viscometer.

[0048] In a specific embodiment, the first temperature is 50°C. In the national quality standard for marine fuel oil, certain requirements are placed on the 50°C viscosity of fuel oil products. If the mixing of the component oils is not carried out at a uniform temperature, heat exchange will occur. Since the heat capacity of each component oil is different and it is difficult to measure or add additional work, it is impossible to determine whether the temperature of the mixed fuel oil product is 50°C. In this case, the predicted viscosity of the mixed fuel oil cannot be used as the 50°C viscosity. When the viscosity of all component oils is 50°C, according to the second law of thermodynamics, heat exchange will not occur between component oils at the same temperature, and the temperature after mixing will remain unchanged. Therefore, if the viscosity of the component oils is unified at 50°C, the viscosity of the mixed finished fuel oil will also be the viscosity value at 50°C, and this viscosity value can be compared with the national standard.

[0049] However, if the 50°C viscosity data of the component oil exceeds the instrument range of the viscometer, it is necessary to measure the viscosity-temperature data that can be measured at a higher temperature, generate a viscosity-temperature curve of the component oil through multiple viscosity-temperature data, and then the 50°C viscosity value of the component oil can be accurately obtained through the viscosity-temperature curve.

[0050] S3, inputting the first viscosity value and the blending mass ratio of each component oil into a preset mixed viscosity value calculation model, so that the mixed viscosity value calculation model calculates the viscosity value of the mixed fuel oil obtained after blending each component oil according to the blending mass ratio, and obtains a second viscosity value of the mixed fuel oil;

[0051] Preferably, the mixed viscosity value calculation model is:

[0052]

[0053] Among them, v blend VBI is the second viscosity value of the mixed fuel oil. blend is the viscosity index of the mixed fuel oil, n is the number of component oil types, x i is the blending mass ratio of the i-th component oil, VBI i is the viscosity index of the i-th component oil, VBI i =LOG(LOG(v i )+p),v i The first viscosity value of the i-th component oil, p is the model parameter of the mixed viscosity value calculation model, p = -171.44*x vr 3 +309.6*x vr 2 -188.22*x vr +38.27,x vr It is the sum of the blending mass proportions of the super heavy component oil in the blending formula.

[0054] (3) The first viscosity value of each component oil and the blending mass ratio of each component oil are input into the mixed viscosity value calculation model of the present invention. The mixed viscosity value calculation model calculates the viscosity value of the mixed fuel oil obtained after blending each component oil according to the blending mass ratio to obtain the second viscosity value of the mixed fuel oil.

[0055] The mixed viscosity value calculation model is:

[0056]

[0057]

[0058] VBI i =LOG(LOG(v i )+p)

[0059] p=-171.44*x vr 3 +309.6*x vr 2 -188.22*x vr +38.273

[0060] Among them, v blend VBI is the second viscosity value of the mixed fuel oil. blend is the viscosity index of the mixed fuel oil, n is the number of component oils, xi is the blending mass ratio of the i-th component oil, VBI i is the viscosity index of the i-th component oil, v i The first viscosity value of the i-th component oil, p is the model parameter of the mixed viscosity value calculation model, x vr It is the sum of the blending mass proportions of the super heavy component oil in the blending formula.

[0061] The construction idea of ​​the mixed viscosity value calculation model is as follows: As the temperature rises, the viscosity value of the super-heavy component increases exponentially, and the viscosity value of the super-heavy component oil is four to seven orders of magnitude higher than the viscosity value of other light component oils at 50°C. Therefore, the model converts the viscosity values ​​of each component oil into a viscosity index that can be linearly added in mass in the form of double LOG. At the same time, according to a large amount of actual production blending data, adjusting the model parameter p can make the model more accurate. At the same time, according to the correlation analysis of a large amount of data, the total proportion of super-heavy component oil x vr It has a large correlation with the parameter p, so p = -171.44*x is used vr 3 +309.6*x vr 2 -188.22*x vr +38.273 can get the parameter p, making the viscosity model more accurate.

[0062] S4. Compare the second viscosity value with a preset viscosity standard. When the second viscosity value meets the viscosity standard, the blending formula is judged to be qualified, and the blending formula is sent to the blending device, so that the blending device blends according to the blending formula to obtain mixed fuel oil.

[0063] Preferably, the method further includes: when the second viscosity value does not meet the viscosity standard, judging that the blending formula is unqualified, and generating prompt information indicating that the blending formula is unqualified, so that the blending personnel can adjust the blending formula according to the prompt information.

[0064] (3) After predicting the second viscosity value of the mixed fuel oil obtained after blending the component oils according to the blending mass ratio through the mixed viscosity value calculation model, the second viscosity value is compared with the viscosity quality standard. If the second viscosity value meets the viscosity quality standard, the blending formula can be judged to be qualified, and the fuel oil can be blended according to the blending formula. If the second viscosity value does not meet the viscosity quality standard, the blending formula can be judged to be unqualified, and the blending formula can be adjusted later.

[0065] The following three specific fuel oil blending cases are used to further illustrate the fuel oil blending method of the present invention:

[0066] As shown in the following three tables, the predicted fuel oil viscosity value at 50°C is calculated by the mixed viscosity value calculation model described in the present invention, and the measured fuel oil viscosity value at 50°C is obtained after blending. The two are compared, and the relative error is small, and the prediction result is more accurate.

[0073] The present invention can achieve the following beneficial effects:

[0074] (1) The range of raw material selection for fuel oil blending can be greatly expanded. The present invention can establish the mixed viscosity value calculation model of the present invention for raw materials that are considered unsuitable for marine fuel oil production in the prior art, and judge whether these raw materials can be successfully blended by simulating the 50°C viscosity results of the blending, and find out the fuel oil blending production plan that cannot be obtained by the prior art;

[0075] (2) It is possible to design and optimize the blending scheme at a lower cost and faster speed. Compared with the prior art, the present invention only needs to measure the viscosity value of the component oils, the instrument is simple, and the measurement time can be controlled within 1 to 2 hours, so that the present invention can be used for rapid decision-making and on-site production guidance, and can be used for planning and scheduling of refineries;

[0076] (3) The present invention does not need to obtain the production formula through a large number of small-scale experiments. It only needs to use computer software to simulate the blending process to obtain the blending result. After the model is successfully blended, it is only necessary to use a small-scale experiment to verify and analyze the result, which greatly reduces the manpower and material costs of formula output and increases the success rate of blending.

[0077] (4) The present invention can flexibly adjust the formula ratio, adjust the mass ratio of the component oils according to the actual inventory, make full use of raw material resources, greatly improve production efficiency, and prevent the waste of raw materials;

[0078] (5) The present invention also improves the accuracy of quality control in the blending of marine fuel oil. The prior art is based on the blending of viscosity based on empirical formulas, and there is a large error in the prediction of the properties of the blended marine fuel oil product. The present invention is based on the characterization of the intrinsic viscosity properties of the marine fuel oil blending raw materials, and can accurately calculate the blending results of the raw materials, thereby more accurately predicting the viscosity properties of the blended marine fuel oil.

[0079] In summary, the present invention provides a blending method for fuel oil. Before blending the component oils, the present invention can calculate the mixed viscosity value of the fuel oil obtained after blending the component oils according to the mixed viscosity value calculation model, and directly predict whether the fuel oil blended according to the blending formula is qualified according to the mixed viscosity value. After judging that the blending formula is qualified, it is only necessary to use a one-time blending quality inspection experiment for verification and analysis. The present invention greatly reduces the manpower and material resources of the national standard quality inspection experiment and the formula output, and increases the success rate of one-time blending of fuel oil.
