Description

Technical Field

[0001] The present invention relates to the technical field of carbon emissions, and particularly relates to a method and device for detecting the balance of carbon footprint values in a refining system. Background Art

[0002] The carbon footprint of a product refers to the total greenhouse gas emissions of a product at each stage of its life cycle. The production process of refining products is complex, involving many devices, complex production processes, and many products produced. Therefore, the calculation of the carbon footprint of the products involved is also large. In order to improve the accuracy of the carbon footprint calculation results and better understand the quality of the collected data, it is necessary to detect whether the carbon footprints in each product participating in carbon transfer during the whole process of product production reach balance. Summary of the Invention

[0003] Theoretically, the carbon footprint values of each product participating in carbon transfer are balanced. However, in related technologies, the method for calculating the carbon footprint of refining products cannot be detailed and in-depth into the refining production process. Only the carbon emissions throughout the process are simplified, and at the same time, all the process carbon emissions caused by the production process are included in a specific product, without considering the impact of other by-products or other material outputs on carbon emission allocation. Therefore, it is inevitable to cause the problem of imbalance in the carbon footprint values of each product participating in carbon transfer, and the existing related technologies do not perform balance detection on the calculated carbon footprint values, and cannot ensure the accuracy and rationality of the carbon footprint value calculation.

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, embodiments of the present invention provide a method and device for detecting the balance of carbon footprint values in a refining system.

[0007] For a refining device with both a non-zero feed carbon emission value and a non-zero device carbon emission value, detect whether the sum of the carbon dioxide generated by the refining device and the carbon dioxide carried by the feed of the refining device is equal to the carbon dioxide carried by the outgoing products participating in carbon transfer of the refining device;

[0008] For a refining device with a non-zero feed carbon emission value and a zero device carbon emission value, detect whether the carbon dioxide carried by the feed of the refining device is equal to the carbon dioxide carried by the outgoing products participating in carbon transfer of the refining device.

[0027] When allocating carbon emissions according to product quality and there are at least two outlet products of its upstream device among the feed products of the refining unit, the carbon footprint value of the outlet product of the refining unit participating in carbon footprint transfer is calculated through the following expression:

[0028] P iCO2 = ∑{[C2 / ∑X Pni + (∑F iCO2 / ∑F i ) * P FiCO2 / ∑X Pni * F iCO2 * X Pni} / [∑(F iCO2 * X Pni )],

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0061] The production process of refining products is complex, involving many devices and a complex production process, resulting in many products. Therefore, the calculation volume of the carbon footprint of the involved products is also large. Theoretically, the carbon footprint values of the various products participating in carbon transfer are balanced. However, in the related art, no balance detection is performed on the calculated carbon footprint values. Since it is impossible to determine whether the carbon footprint values of the products are balanced, the accuracy and rationality of the carbon footprint value calculation cannot be ensured.

[0062] Embodiment

[0063] An embodiment of the present invention provides a method for detecting the balance of the carbon footprint value of a refining system, and its process is as Figure 1 shown, including:

[0064] S1. For a refining device with a zero feed carbon emission value and a non-zero device carbon emission value, detect whether the carbon dioxide generated by the refining device is equal to the carbon dioxide carried by the outgoing products participating in carbon transfer by the refining device.

[0065] S2. For a refining device with both non-zero feed carbon emission value and device carbon emission value, detect whether the sum of the carbon dioxide generated by the refining device and the carbon dioxide carried by the feed of the refining device is equal to the carbon dioxide carried by the outgoing products participating in carbon transfer by the refining device.

[0066] S3. For a refining device with a non-zero feed carbon emission value and a zero device carbon emission value, detect whether the carbon dioxide carried by the feed of the refining device is equal to the carbon dioxide carried by the outgoing products participating in carbon transfer by the refining device.

[0067] Preferably, the above method further includes:

[0068] For a refining device with a detection result of yes, it is considered that the carbon footprint is balanced, and a prompt message of carbon footprint balance is output;

[0069] For a refining device with a detection result of no, it is considered that the carbon footprint is unbalanced, and a prompt message of carbon footprint imbalance is output.

[0070] Whether the carbon footprint is balanced or not will further verify whether the method for calculating the carbon footprint is accurate. Therefore, it is necessary to perform balance detection on the carbon footprint of the products to further ensure the accuracy of the data.

[0071] Preferably, in steps S1, S2 and S3, the carbon dioxide carried by the discharged products of the refining unit participating in carbon transfer is ∑(P i *P iCO2 ), where P i is the product quantity, and P iCO2 is the carbon footprint value of the discharged products participating in carbon footprint transfer.

[0072] Preferably, in step S1 above, when the refining unit is an atmospheric and vacuum distillation unit with a zero feed carbon emission value and a non-zero unit carbon emission value, the carbon footprint value of the discharged products participating in carbon footprint transfer is calculated through the following expression:

[0073] In the case of allocating carbon emissions according to product quality, the carbon footprint value of the discharged products of the refining unit participating in carbon footprint transfer is calculated through the following expression:

[0074] P iCO2 = C1 / ∑X Pi

[0075] where P iCO2 is the carbon footprint value of the i-th product of the refining unit, C1 is the unit feed carbon emission value of the refining unit, and X Pi is the mass yield of the i-th product participating in carbon footprint transfer;

[0076] In the case of allocating carbon emissions according to specific principles other than product quality, the carbon footprint value of the discharged products of the refining unit participating in carbon footprint transfer is calculated through the following expression:

[0077] P iCO2 = C1*a i / ∑(X Pi *a i )

[0078] where P iCO2 is the carbon footprint value of the i-th product of the refining unit, C1 is the unit feed carbon emission value 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 specific principle coefficient of the i-th product.

[0079] The structure of the refining system in this embodiment is shown in Figure 2 , and includes an atmospheric and vacuum distillation unit, a secondary processing unit and a blending unit 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. Taking Figure 2Taking the refining and chemical system shown as an example, the feed of the atmospheric and vacuum distillation unit is crude oil, and the crude oil does not carry carbon dioxide. Therefore, only the unit itself generates carbon dioxide. The outlet products of the atmospheric and vacuum distillation unit include straight-run naphtha, straight-run diesel, wax oil components, and residue oil components. Then, according to the distribution principle of carbon footprint calculation, the carbon footprint value of the outlet products of the refining and chemical unit participating in carbon footprint transfer is calculated according to the above expression.

[0080] The specific principles in this embodiment include, but are not limited to, the principle of distribution by calorific value and the principle of distribution by product value. The specific principle coefficients include, but are not limited to, the calorific value coefficient and the product value coefficient.

[0081] Preferably, in the above step S2, when the refining and chemical unit is a secondary processing unit with non-zero feed carbon emission value and unit carbon emission value, the carbon footprint value of the outlet product participating in carbon footprint transfer is calculated through the following expression:

[0082] In the case of distributing carbon emissions according to product quality and there is an outlet product of its upstream unit in the feed products of the refining and chemical unit, the carbon footprint value of the outlet products of the refining and chemical unit participating in carbon footprint transfer is calculated through the following expression:

[0083] P iCO2 =C2 / ∑X Pi +(∑F iCO2 / ∑F i )*P FiCO2 / ∑X Pi

[0084] Wherein, P iCO2 is the carbon footprint value of the i-th product of the refining and chemical unit, C2 is the unit feed carbon emission value of the refining and chemical 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,

[0085] In the case of distributing carbon emissions according to specific principles other than product quality and there is an outlet product of its upstream unit in the feed products of the refining and chemical unit, the carbon footprint value of the outlet products of the refining and chemical unit participating in carbon footprint transfer is calculated through the following expression:

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

[0087] Among them, P iCO2 is the carbon footprint value of the i-th product of the refining and chemical device, C2 is the carbon emission value per unit feed of the refining and chemical device, 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, a i is the specific principle coefficient per unit of the i-th product.

[0088] Taking the refining system shown Figure 2 as an example, the feeds of the hydrocracking unit are wax oil components and hydrogen. Since hydrogen does not carry carbon dioxide, the feed participating in carbon footprint transfer in the hydrocracking unit is only the wax oil component, which belongs to the case of one outgoing product of the upstream unit. The outgoing products of the hydrocracking unit are hydrocracked gasoline and hydrocracked diesel. Then, according to the distribution principle of carbon footprint calculation, the carbon footprint value of the outgoing products of the refining device participating in carbon footprint transfer is calculated according to the above expression.

[0089] In the case of allocating carbon emissions according to product quality and there are at least two outgoing products of its upstream unit in the feed products of the refining device, the carbon footprint value of the outgoing products of the refining device participating in carbon footprint transfer is calculated through the following expression:

[0090] P iCO2 = ∑{[C2 / ∑X Pni + (∑F iCO2 / ∑F ni ) * P FiCO2 / ∑X Pni * F iCO2 * X Pni} / [∑(F iCO2 * X Pni )],

[0091] Among them, P iCO2 is the carbon footprint value of the i-th product of the refining device, C2 is the carbon emission value per unit feed of the refining device, X Pni is the corresponding mass yield of the i-th product of the n-th feed 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,

[0092] When allocating carbon emissions according to specific principles other than product quality and there are at least two outgoing products of its upstream unit in the feed products of the refining unit, the carbon footprint value of the outgoing products of the refining unit participating in carbon footprint transfer is calculated through the following expression:

[0093] 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 )

[0094] Among them, P iCO2 is the carbon footprint value of the i-th product of the refining unit, C2 is the unit feed carbon emission value of the refining unit, X Pni is the corresponding mass yield of the i-th product of the n-th feed participating in carbon footprint transfer, F iCO2 is the feed quantity of the i-th feed participating in carbon footprint transfer, ∑F i is the total feed quantity, P FiCO2 is the carbon footprint value of the i-th feed participating in carbon footprint transfer, a i is the unit specific principle coefficient of the i-th product.

[0095] Taking Figure 2 the shown refining system as an example, the feed products of the fluid catalytic cracking unit are wax oil components and hydrocracking tail oil, both of which carry carbon dioxide and participate in carbon transfer, belonging to the situation where there are at least two outgoing products of its upstream unit. The outgoing products of the fluid catalytic cracking unit are catalytic dry gas, catalytic liquefied gas, catalytic gasoline, catalytic diesel, and catalytic slurry. Then, according to the allocation principle of carbon footprint calculation, the carbon footprint value of the outgoing products of the refining unit participating in carbon footprint transfer is calculated according to the above expression.

[0096] Preferably, in the above step S3, when the refining unit is a blending unit with a non-zero feed carbon emission value and a zero unit carbon emission value, the carbon footprint value of the outgoing products participating in carbon footprint transfer is calculated through the following expression:

[0097] The carbon footprint value of the outgoing products of the refining unit participating in carbon footprint transfer is calculated through the following expression:

[0098] P iCO2 = ∑(F iCO2 * P FiCO2 ) / ∑Pi

[0099] Among them, P iCO2 is the carbon footprint value of the i-th product of the refining unit, and F iCO2 is the feed quantity of the i-th feedstock participating in carbon footprint transfer, and P FiCO2 is the carbon footprint value of the i-th feedstock participating in carbon footprint transfer, and P i is the product quantity.

[0100] The blending unit blends various products. Therefore, this unit does not generate carbon dioxide. Only the gasoline and diesel, which are the outgoing products of the blending unit, carry carbon dioxide. Calculate the carbon footprint value of the outgoing products of the refining unit participating in carbon footprint transfer according to the above calculation method.

[0101] Preferably, in the above step S1, the carbon dioxide generated by the refining unit with a zero feed carbon emission value and a non-zero unit carbon emission value is ∑F i *C, where C is the unit feed carbon emission value of the unit, and ∑F i is the total feed quantity.

[0102] Preferably, in the above step S2, the carbon dioxide generated by the refining unit with non-zero feed carbon emission value and unit carbon emission value is ∑F i *C + ∑(F iCO2 *P FiCO2 ), where F iCO2 is the feed quantity of the i-th feedstock participating in carbon footprint transfer, and P FiCO2 is the carbon footprint value of the i-th feedstock participating in carbon footprint transfer.

[0103] Preferably, in the above step S3, the carbon dioxide carried by the feed of the refining unit is ∑(F iCO2 *P FiCO2 ), where F iCO2 is the feed quantity of the i-th feedstock participating in carbon footprint transfer, and P FiCO2 is the carbon footprint value of the i-th feedstock participating in carbon footprint transfer.

[0104] Preferably, the above method further includes:

[0105] For the refining system, detect whether the sum of the carbon dioxide amounts generated by all refining units is equal to the sum of the carbon dioxide carried by the final outgoing products of the refining units participating in carbon transfer. The final outgoing products refer to the outgoing products that do not participate in subsequent processing procedures;

[0106] The expression of the sum of the carbon dioxide amounts generated by all refining units is as follows: ∑(F i *C), where C is the unit feed carbon emission value of the unit, and F i is the feed quantity of the refining unit;

[0107] The expression for the sum of carbon dioxide carried by the final discharge products of the refining unit participating in carbon transfer is as follows: ∑(P i *P iCO2 ), where P i is the product quantity, and P iCO2 is the carbon footprint value of the i-th product of the refining unit.

[0108] To further verify the accuracy of this method, the following takes the refining system shown in Figure 2 as an example to 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 participating in carbon transfer. Among them, the carbon emission value per unit feed, feed quantity, and unit carbon emissions of each unit are shown in Table 1.

[0114]

[0115] Under the condition that the carbon emission allocation requirement is to allocate according to product value, the carbon footprint values of each discharge product of the atmospheric and vacuum distillation unit participating in carbon transfer are calculated through the following expression:

[0116] P iCO2 = C1 * a i / ∑(X Pi * a i )

[0117] 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:
