Description

Technical Field

[0001] The present invention relates to the technical field of carbon emissions, and in particular, to a method, device, and system for obtaining the carbon footprint of products of a refining and chemical device. Background Art

[0002] Carbon footprint refers to the greenhouse gas emission inventory during the entire life cycle or part of the life cycle of a product, including production, transportation, use, and disposal. By analyzing the carbon footprint of a product, the specific sources of carbon emissions can be quantified, and the carbon emission values of each link can be intuitively expressed, so as to propose and formulate reasonable and applicable "low-carbon" and "emission reduction" plans and solutions to achieve effective management of the carbon footprint.

[0003] The production process of refining products in the refining industry is complex, involving many devices and complicated processes, and there are also many products produced. Therefore, the process of determining the carbon footprint data in the refining device is complex, and the calculation amount of the carbon footprint value is large. At present, in related technologies, the total carbon emissions during the production process of refining products can be calculated based on the product quality principle, and the carbon emission coefficients of the refining device for different products can be calculated. However, it is impossible to reasonably allocate the carbon emissions caused by the product during the production process to each product to calculate the carbon footprint value of the refining product. Summary of the Invention

[0004] The existing method for calculating the carbon footprint of products of a refining device can calculate the total carbon emissions during the production process of refining products based on the product quality principle. However, there are many types of products produced by the refining device, and the requirements for carbon emission allocation are also different. The existing method for calculating the carbon footprint of refining products cannot delve into the refining production process in detail. It only simplifies the carbon emissions of the whole process, and at the same time includes all the process carbon emissions caused by the production process into specific products, without considering the impact of other by-products or other material outputs on carbon emission allocation. Under other carbon emission allocation requirements, if the carbon footprint value of the product is calculated only according to the mass allocation principle, the calculated result will have an error compared with the actual result. Therefore, the calculated carbon footprint value of the products of the refining device will be inaccurate. In addition, in the existing method, the carbon emission data of each product in the refining device cannot be displayed in real time. When the carbon footprint value is abnormal, the staff cannot immediately determine which device's data is abnormal.

[0058] The existing methods for calculating the carbon footprint of refining products cannot be detailed and in-depth into the refining production process. Only the carbon emissions of the whole process are simplified, and at the same time, all the process carbon emissions caused by the production process are included in specific products, without considering the impact of other by-products or other material outputs on carbon emission allocation. It is impossible to reasonably allocate the carbon emissions caused by products during the production process to each product to calculate the carbon footprint value of refining products, and the carbon footprint data of refining device products cannot be displayed in real time for users to view in time, so the work efficiency cannot be improved.

[0059] Embodiment 1

[0060] The embodiment of the present invention provides a method for obtaining the carbon footprint of refining device products. The process is as shown in Figure 1 and includes the following steps:

[0061] S1. Receive the carbon footprint calculation request for refining device products, and parse out the carbon emission allocation requirements included in the carbon footprint calculation request for refining device products.

[0062] S2. Determine the specified parameters for calculating the carbon footprint of refining device products according to the type of refining device.

[0063] In this embodiment, due to the different positions of the refining device in the refining system, the specified parameters for calculating the carbon footprint of the refining device products are also different. Among them, the refining system is as shown in Figure 2 In Figure 2 , the atmospheric and vacuum distillation unit is a primary processing unit, the hydrocracking unit and the fluid catalytic cracking unit are both secondary processing units, and the gasoline blending unit and the diesel blending unit are blending units.

[0064] S3. Based on the distribution principle for carbon emission allocation requirements, determine the carbon footprint data of the refinery unit products according to the specified parameters and the unit distribution principle coefficients of each refinery unit product.

[0065] Preferably, in the above step S1, receiving the carbon footprint calculation request for refinery unit products includes:

[0066] The control server receives the carbon footprint calculation request for refinery unit products sent by the terminal device in the refinery unit;

[0067] The carbon footprint calculation request for refinery unit products carries the refinery unit type, refinery unit identification, terminal device identification, and carbon emission allocation requirements; the refinery unit type includes at least one of the atmospheric and vacuum distillation unit, secondary processing unit, and blending unit.

[0068] When carbon footprint calculation is required, the terminal device in the refinery unit sends a carbon footprint calculation request for refinery unit products to the control server. The control server calculates the corresponding carbon footprint value through the carbon footprint acquisition method of this method based on the refinery unit type, refinery unit identification, terminal device identification, and carbon emission allocation requirements carried in the request, so as to achieve intelligent control.

[0069] Preferably, after determining the carbon footprint data of the refinery unit products, it further includes:

[0070] The control server sends the determined carbon footprint data of the refinery unit products to the terminal device in the corresponding refinery unit according to the refinery unit identification and / or terminal device identification in the received carbon footprint calculation request for refinery unit products.

[0071] Preferably, in the above step S2, determining the specified parameters for carbon footprint calculation of refinery unit products includes:

[0072] In the case where the refinery unit is an atmospheric and vacuum distillation unit, the specified parameters for carbon footprint calculation of refinery unit products include the unit feed carbon emission value of the refinery unit and the mass yield of the refinery products participating in carbon footprint transfer.

[0073] In the case where the refinery unit is a secondary processing unit, the specified parameters for carbon footprint calculation of refinery unit products include the unit feed carbon emission value of the refinery unit, the corresponding mass yields of each product under the nth feed participating in carbon footprint transfer, the feed amounts of each feed participating in carbon footprint transfer, the total feed amount, and the carbon footprint values of each feed participating in carbon footprint transfer.

[0074] In the case where the refinery unit is a blending unit, the specified parameters for carbon footprint calculation of refinery unit products include the feed amounts of each feed participating in carbon footprint transfer, the carbon footprint values of each feed participating in carbon footprint transfer, and the amounts of each product.

[0075] In the refining system, since the types of refining units are different, the parameters involved in the calculation will also vary. The specific calculation of the carbon footprint of a refining unit should be based on the specified parameters involved in carbon transfer in the unit to ensure the accuracy of the carbon footprint value calculation.

[0076] Preferably, in the above step S3, determining the carbon footprint value of the product of the refining unit includes:

[0077] Based on the following expression, calculate the carbon footprint value of the product of the atmospheric and vacuum distillation unit:

[0078] P iCO2 = C1 * a i / ∑(X Pi * a i )

[0079] Wherein, P iCO2 is the carbon footprint value of the i-th product of the refining unit, C1 is the carbon emission value per unit feed of the refining unit, X Pi is the mass yield of the i-th product participating in carbon footprint transfer, and a i is the unit distribution principle coefficient of the i-th product.

[0080] In this embodiment, the distribution principle coefficient includes but is not limited to the calorific value coefficient and the product value coefficient.

[0081] When the feed of the secondary processing unit includes one kind of discharge from the upstream unit, based on the following expression, calculate the carbon footprint value of the product of the secondary processing unit:

[0082] P iCO2 = C2 * a i / ∑(X Pi * a i ) + (∑F iCO2 / ∑F i ) * P FiCO2 * a i / ∑(X Pi * a i )

[0083] Wherein, P iCO2 is the carbon footprint value of the i-th product of the refining unit, C2 is the carbon emission value per unit feed of the refining unit, X Pi is the mass yield of the i-th product participating in carbon footprint transfer, F iCO2 is the feed amount of the i-th feed participating in carbon footprint transfer, ∑F i is the total feed amount, P FiCO2 is the carbon footprint value of the i-th feed participating in carbon footprint transfer, and a i is the unit distribution principle coefficient of the i-th product.

[0084] For the structure of the refining system in this embodiment, seeFigure 2 As shown, it includes an atmospheric and vacuum distillation unit, a secondary processing unit, and a blending unit that are connected in sequence. The secondary processing unit is further divided into a hydrocracking unit and a fluid catalytic cracking unit, and the blending unit is further divided into a gasoline blending unit and a diesel blending unit. The feed of the hydrocracking unit in the secondary processing unit is wax oil components and hydrogen. Since hydrogen does not carry carbon dioxide, the feed participating in the carbon footprint transfer of the hydrocracking unit is only the wax oil components, which belongs to the case of one output product of the upstream unit.

[0085] In the case where the feed of the secondary processing unit includes at least two outputs of the upstream unit, based on the following expression, calculate the carbon footprint value of the product of the secondary processing unit:

[0086] P iCO2 = ∑[C2 * F iCO2 * X Pni * a i / ∑(X Pni * a i ) + (∑F iCO2 / ∑F i ) * P FiCO2 * a i / ∑(X Pni * a i )] / ∑(F iCO2 * X Pni )

[0087] Wherein, P iCO2 is the carbon footprint value of the i-th product of the refining unit, C2 is the carbon emission value per unit feed of the refining unit, X Pni is the corresponding mass yield of the n-th feed participating in the carbon footprint transfer for the i-th product, F iCO2 is the feed amount of the i-th feed participating in the carbon footprint transfer, ∑F i is the total feed amount, P FiCO2 is the carbon footprint value of the i-th feed participating in the carbon footprint transfer, a i is the unit allocation principle coefficient of the i-th product.

[0088] Based on the following expression, calculate the carbon footprint value of the product of the blending unit:

[0089] P iCO2 = ∑(F iCO2 * P FiCO2 ) / ∑P i

[0090] Wherein, P iCO2 is the carbon footprint value of the i-th product of the refining unit, F iCO2 is the feed amount of the i-th feed participating in the carbon footprint transfer, P FiCO2 is the carbon footprint value of the i-th feed participating in the carbon footprint transfer, Pi is the product quantity.

[0091] See Figure 2 the shown refining system. The feed of the fluid catalytic cracking unit in the secondary processing unit is wax oil component and hydrocracking tail oil, both of which carry carbon dioxide and participate in carbon transfer, belonging to the situation of at least two discharge products of its upstream unit.

[0092] Below, taking Figure 2 the shown refining system as an example, based on the above method for obtaining the product carbon footprint of the refining unit, calculate the carbon footprint values of the discharge products of the atmospheric and vacuum distillation unit, hydrocracking unit, fluid catalytic cracking unit, gasoline blending unit, and diesel blending unit. Among them, the carbon emissions per unit feed and the total carbon emissions of each unit are shown in Table 1 below.

[0093] Table 1

[0094] Device Name Carbon Emission Value per Unit Feed Feed Rate Device Carbon Emission Atmospheric and Vacuum Distillation Unit 0.05 100 5 Hydrocracking Unit 0.1 20.3 2.03 Fluid Catalytic Cracking Unit 0.15 22.03 3.3045 Gasoline Blending Unit 0 31.8305 0 Diesel Blending Unit 0 24.4545 0

[0095] Through the following expression, calculate the carbon footprint values of the discharge products of the atmospheric and vacuum distillation unit:

[0096] P iCO2 = C1 * a i / ∑(X Pi * a i )

[0097] Assume the crude oil feed quantity is 100. The feed and discharge information of the atmospheric and vacuum distillation unit is shown in Table 2 below.

[0098] Table 2

[0099]

[0100]

[0101] In Table 2 above, all dry gas components and unit losses do not allocate carbon emissions and do not participate in the calculation of carbon footprint values. The carbon footprint value of the purchased crude oil is zero. According to the feed and discharge information of the atmospheric and vacuum distillation unit, the carbon footprint value of the straight-run naphtha of the atmospheric and vacuum distillation unit is:

[0102] P iCO2 = 0.05 * 1.5 / (1.5 * 0.15 + 1.2 * 0.1 + 0.8 * 0.4 + 0.5 * 0.3) = 0.09202454

[0103] According to the feed and discharge information of the atmospheric and vacuum distillation unit, the carbon footprint value of the straight-run diesel of the atmospheric and vacuum distillation unit is:

[0104] P iCO2= 0.05 * 1.2 / (1.5 * 0.15 + 1.2 * 0.1 + 0.8 * 0.4 + 0.5 * 0.3) = 0.073619632

[0105] Based on the feed and product information of the atmospheric and vacuum distillation unit, the carbon footprint value of the wax oil component of the atmospheric and vacuum distillation unit is:

[0106] P iCO2 = 0.05 * 0.8 / (1.5 * 0.15 + 1.2 * 0.1 + 0.8 * 0.4 + 0.5 * 0.3) = 0.049079755

[0107] Based on the feed and product information of the atmospheric and vacuum distillation unit, the carbon footprint value of the residue oil component of the atmospheric and vacuum distillation unit is:

[0108] P iCO2 = 0.05 * 0.5 / (1.5 * 0.15 + 1.2 * 0.1 + 0.8 * 0.4 + 0.5 * 0.3) = 0.030674847

[0109] The hydrocracking unit type is a secondary processing unit and its feed includes a product of the atmospheric and vacuum distillation unit. Based on the following expression, calculate the carbon footprint value of the product of the secondary processing unit:

[0110] P iCO2 = C2 * a i / ∑(X Pi * a i ) + (∑F iCO2 / ∑F i ) * P FiCO2 * a i / ∑(X P i * a i )

[0111] The feed and product information of the hydrocracking unit is shown in Table 3 below.

[0112] Table 3

[0113]

[0114] In Table 3 above, all dry gas components and unit losses do not allocate carbon emissions and are not involved in the calculation of the carbon footprint value. The carbon footprint value of the purchased hydrogen is zero. Therefore, through the following expression, calculate the carbon footprint value of the hydrocracked gasoline of the hydrocracking unit:

[0115] P iCO2 = 0.1 * 1.5 / (0.4 * 1.5 + 0.49 * 1.2 + 0.1 * 1) + (20 / 20.3)

[0116] *0.05263158*1.5 / (0.4*1.5 + 0.49*1.2 + 0.1*1) = 0.172773026

[0117] The carbon footprint value of the hydrocracked diesel in the hydrocracking unit is calculated through the following expression:

[0118] P iCO2 = 0.1*1.2 / (0.4*1.5 + 0.49*1.2 + 0.1*1) + (20 / 20.3)

[0119] *0.05263158*1.2 / (0.4*1.5 + 0.49*1.2 + 0.1*1) = 0.138218421

[0120] The carbon footprint value of the hydrocracked tail oil in the hydrocracking unit is calculated through the following expression:

[0121] P iCO2 = 0.1*1 / (0.4*1.5 + 0.49*1.2 + 0.1*1) + (20 / 20.3)

[0122] *0.05263158*1 / (0.4*1.5 + 0.49*1.2 + 0.1*1) = 0.115182017

[0123] The catalytic cracking unit is a secondary processing unit and the feed includes the product of a atmospheric and vacuum distillation unit and the product of a hydrocracking unit. Based on the following expression, the carbon footprint value of the product of the secondary processing unit is calculated:

[0124] P iCO2 = ∑[C2*F iCO2 *X Pni *a i / ∑(X Pni *a i ) + (∑F iCO2 / ∑F ni )*P FiCO2 *a i / ∑(X Pni *

[0125] a i )] / ∑(F iCO2 *X Pni )

[0126] The feed and product information of the catalytic cracking unit is shown in Table 4 below.

[0127] Table 4

[0128]

[0129] In Table 4 above, all dry gas components and plant losses do not allocate carbon emissions and are not involved in the calculation of the carbon footprint value. Therefore, through the following expression, the carbon footprint value of the catalytic liquefied gas in the fluid catalytic cracking unit is calculated:

[0130] P iCO2 ={[0.15 * 20 * 0.2 * 1.3 / (0.2 * 1.3 + 0.4 * 1.5 + 0.2 * 1.2 + 0.1 * 0.4) + 20 / 22.03 * 0.049079755 * 1.3 / (0.2 * 1.3 + 0.4 * 1.5 + 0.2 * 1.2 + 0.1 * 0.4)] + [0.15 * 2.03 * 0.19 * 1.3 / (0.19 * 1.3 + 0.35 * 1.5 + 0.25 * 1.2 + 0.075 * 0.4) + 2.03 / 22.03 * 0.115182017 * 1.3 / (0.19 * 1.3 + 0.35 * 1.5 + 0.25 * 1.2 + 0.075 * 0.4)]} / (20 * 0.2 + 2.03 * 0.19) = 0.234567095
