Description

Technical Field

[0001] The present disclosure relates to the technical field of carbon emissions, and particularly to a method and device for calculating the carbon footprint value of products in a refining system, equipment, and storage medium. Background Art

[0002] The production process of refining products is complex, involving many devices and a complex process, and generating many products. The factors causing carbon emissions throughout the production process are also diverse. For example, the carbon emissions generated by different products and different devices are also different, and the resulting carbon footprints are also diverse. Especially for a large refining system, where multiple devices are interconnected, there is also a problem of carbon footprint transfer.

[0003] Currently, in the related technologies for calculating carbon emissions, some calculation methods can be used to simply calculate the carbon emissions throughout the process, calculate the total carbon emissions of petrochemical products during the production process, and calculate the carbon emission coefficients of petrochemical devices for different products; the process carbon emissions caused by the production process are generally all counted in a certain specific product, and petrochemical devices are also considered separately. Summary of the Invention

[0004] The inventors of the present application found that the current related technologies cannot reasonably allocate the carbon emissions caused by products during the production process to each product to achieve the calculation of the carbon footprint value of refining products. In addition, in the related technologies, the method for calculating the carbon footprint of refining products cannot be detailed and in-depth into the refining production process, only simplifies the carbon emissions throughout the process, and at the same time counts all the process carbon emissions caused by the production process into a specific product, without considering the impact of other by-products or other material outputs on carbon emission allocation. At the same time, the carbon footprint transfer relationship between devices is not considered, so the carbon footprint in the refining system cannot be accurately determined.

[0111] According to the feed and product information of the atmospheric and vacuum distillation unit, the carbon footprint values of the straight-run naphtha, straight-run diesel, wax oil component, and residue component from the atmospheric and vacuum distillation unit are as follows:

[0112] P iCO2 = 0.05 / 0.95 = 0.05263158

[0113] The hydrocracking unit is a secondary processing unit and its feed includes a product from the atmospheric and vacuum distillation unit. The feed and product information of the hydrocracking unit is shown in Table 3 below.

[0114] Table 3

[0115]

[0116] When the carbon emission allocation requirement is to allocate according to the product value, based on the following expression, calculate the carbon footprint value of the products of the secondary processing unit:

[0117] P iCO2 = C2 * a i / ∑(X Pi * a i ) + (∑F iCO2 / ∑F i ) * P FiCO2 * a i / ∑(X Pi * a i )

[0118] In Table 3 above, all dry gas components and unit losses do not allocate carbon emissions and do not participate in the calculation of the carbon footprint value. The carbon footprint value of the purchased hydrogen is zero. Through the following expression, calculate the carbon footprint value of the hydrocracked gasoline of the hydrocracking unit:

[0119] P iCO2 = 0.1 * 1.5 / (0.4 * 1.5 + 0.49 * 1.2 + 0.1 * 1) + (20 / 20.3) * 0.049079755 * 1.5 / (0.4 * 1.5 + 0.49 * 1.2 + 0.1

[0120] * 1) = 0.172773026

[0121] Through the following expression, calculate the carbon footprint value of the hydrocracked diesel of the hydrocracking unit:

[0122] P iCO2 = 0.1 * 1.2 / (0.4 * 1.5 + 0.49 * 1.2 + 0.1 * 1) + (20 / 20.3) * 0.049079755 * 1.2 / (0.4 * 1.5 + 0.49 * 1.2 + 0.1

[0123] * 1) = 0.138218421

[0124] Through the following expression, calculate the carbon footprint value of the hydrocracked tail oil of the hydrocracking unit:

[0125] P iCO2 = 0.1 * 1 / (0.4 * 1.5 + 0.49 * 1.2 + 0.1 * 1) + (20 / 20.3) * 0.049079755 * 1 / (0.4 * 1.5 + 0.49 * 1.2 + 0.1 * 1)

[0126] = 0.115182017

[0127] When the carbon emission allocation requirement is mass-based allocation, the carbon footprint values of the outlet products of the hydrocracking unit are calculated through the following expression:

[0128] P iCO2 = C2 / ∑X Pi + (∑F iCO2 / ∑F i ) * P FiCO2 / ∑X Pi

[0129] The carbon footprint values of the hydrocracked gasoline, hydrocracked diesel, and hydrocracked tail oil of the hydrocracking unit are calculated through the following expression:

[0130] P iCO2 = 0.1 / 0.99 + (20 / 20.3) * 0.05263158 / 0.99 = 0.15338765

[0131] The catalytic cracking unit is a secondary processing unit and the feed includes the outlets of more than one atmospheric and vacuum distillation unit and hydrocracking unit. The feed and outlet information of the catalytic cracking unit is shown in Table 4 below.

[0133]

[0134]

[0135] When the carbon emission allocation requirement is product value-based allocation, based on the following expression, the carbon footprint values of the products of the secondary processing unit are calculated:

[0136] P iCO2 = ∑[C2 * F iCO2 * X Pni * a i / ∑(X Pni * a i ) + (∑F iCO2 / ∑F ni ) * P FiCO2 * a i / ∑(X Pni * a i )]

[0137] / ∑(F iCO2 * X Pni )

[0138] In Table 4 above, all dry gas components and unit losses do not allocate carbon emissions and are not involved in the calculation of carbon footprint values. Therefore, through the following expression, the carbon footprint value of the catalytic liquefied gas of the catalytic cracking unit is calculated:
