[0050] See Figure 1 , embodiments of the present disclosure provide a method for determining the carbon footprint of the products of a refining and chemical device, including the following steps:

[0051] S1. Determine the type of refining unit based on the feed carbon emissions and the carbon emissions of the unit itself in the refining unit.

[0052] In this embodiment, the types of refining units include those with zero feed carbon emissions and non-zero unit carbon emissions, those with non-zero feed carbon emissions and zero unit carbon emissions, and those with both non-zero feed carbon emissions and unit carbon emissions.

[0053] In some embodiments, the refining unit corresponding to the type with zero feed carbon emissions and non-zero unit carbon emissions can be a atmospheric and vacuum distillation unit. The refining unit corresponding to the type with non-zero feed carbon emissions and zero unit carbon emissions can be a secondary processing unit, such as a hydrocracking unit and a fluid catalytic cracking unit. The refining unit corresponding to the type with both non-zero feed carbon emissions and unit carbon emissions can be a blending unit, such as a gasoline blending unit and a diesel blending unit.

[0054] S2. Construct a carbon footprint calculation model for each type of refining unit according to the preset mass distribution principle.

[0055] In this step, for a refining unit with feed carbon emissions, the modeling parameters for constructing the carbon footprint calculation model include feed carbon emission data and the mass yield of the product. For a refining unit with unit carbon emissions, the modeling parameters for constructing the carbon footprint calculation model include the feed quantity, the product quantity, and the carbon footprint of each feed.

[0056] S3. Determine the product carbon footprint of each type of refining unit according to the carbon footprint calculation model corresponding to each type of refining unit.

[0057] In this step, according to the type of refining unit, determine the model input parameters for carbon footprint calculation; collect the model input parameters from the refining unit and input them into the carbon footprint calculation model to determine the product carbon footprint of the refining unit. The model input parameters include at least one of feed carbon emission data, the mass yield of the product, the feed quantity, the total feed quantity, the product quantity, and the carbon footprint of each feed.

[0058] In this embodiment, in step S2, the constructing a carbon footprint calculation model for each type of refining unit according to the preset mass distribution principle includes:

[0059] When the type of the refining unit is the type with zero feed carbon emissions and non-zero unit carbon emissions, the carbon footprint calculation model corresponding to the refining unit is the following expression:

[0060] P iCO2 = C1 / ∑X Pi

[0061] Where P iCO2is the carbon footprint value of the i-th product of the refining and chemical device, C1 is the carbon emission value per unit feed of the refining and chemical device, and X Pi is the mass yield of the i-th product participating in carbon footprint transfer.

[0062] In this embodiment, in step S2, constructing the carbon footprint calculation model corresponding to each type of refining and chemical device according to the preset mass distribution principle includes:

[0063] When the type of the refining and chemical device is such that the carbon emission value per unit feed is not zero and the device carbon emission value is zero, the carbon footprint calculation model corresponding to the refining and chemical device is the following expression:

[0064] P iCO2 = ∑(F iCO2 *P FiCO2 ) / ∑P i

[0065] where P iCO2 is the carbon footprint value of the i-th product of the refining and chemical device, F iCO2 is the feed amount of the i-th feed participating in carbon footprint transfer, P FiCO2 is the carbon footprint value of the i-th feed participating in carbon footprint transfer, and P i is the product amount.

[0066] In this embodiment, in step S2, the type of the refining and chemical device is such that both the carbon emission value per unit feed and the device carbon emission value are not zero. Constructing the carbon footprint calculation model corresponding to each type of refining and chemical device according to the preset mass distribution principle includes:

[0067] When the type of the refining and chemical device is such that both the carbon emission value per unit feed and the device carbon emission value are not zero, according to the feed types of the refining and chemical device, construct the carbon footprint calculation model under different feed type conditions according to the preset mass distribution principle; the carbon footprint calculation model under different feed type conditions includes the carbon footprint calculation model under single-feed conditions and the carbon footprint calculation model under multi-feed conditions.

[0068] In this embodiment, the carbon footprint calculation model under single-feed conditions is the following expression:

[0069] P iCO2 = C2 / ∑X Pi + (∑F iCO2 / ∑F i ) * P FiCO2 / ∑X Pi

[0070] where 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, and X PiThe mass yield of the i-th product participating in the carbon footprint transfer, F iCO2 The feed rate of the i-th feed participating in the carbon footprint transfer, ∑F i The total feed rate, P FiCO2 The carbon footprint value of the i-th feed participating in the carbon footprint transfer.

[0071] In this embodiment, the carbon footprint calculation model under the multiple feed conditions is the following expression:

[0072] P iCO2 = ∑{[C2 / ∑X Pni +(∑F iCO2 / ∑F ni ) * P FiCO2 / ∑X Pni * F iCO2 * X Pni} / [∑(F iCO2 *

[0073] X Pni )]

[0074] Among them, 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 i-th product of the n-th feed participating in the carbon footprint transfer, F iCO2 is the feed rate of the i-th feed participating in the carbon footprint transfer, ∑F i is the total feed rate, P FiCO2 is the carbon footprint value of the i-th feed participating in the carbon footprint transfer.

[0075] Taking the refining system as shown in Figure 2 as an example, the refining system includes an atmospheric and vacuum distillation unit, a hydrocracking unit, a fluid catalytic cracking unit, a gasoline blending unit, and a diesel blending unit; calculate the carbon footprint values of the outlet 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.

[0076] Table 1

[0077] Device Name Carbon Emission Value per Unit Feedstock Feedstock Quantity 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 31.83 0 Diesel Blending Unit 0 24.45 0

[0078] The type of the atmospheric and vacuum distillation unit is the type with zero carbon emission value per unit feed and non-zero carbon emission value of the unit. Calculate the carbon footprint values of the outlet products of the atmospheric and vacuum distillation unit, and use the carbon footprint calculation model of the type with zero carbon emission value per unit feed and non-zero carbon emission value of the unit for calculation; therefore, calculate the carbon footprint values of the outlet products of the atmospheric and vacuum distillation unit through the following expression:

[0079] PiCO2 = C1 / ∑X Pi

[0080] The crude oil feed rate can be preset values such as 100, 200, etc. Assuming the crude oil feed rate is 100, the feed and product discharge information of the atmospheric and vacuum distillation unit is as shown in Table 2 below.

[0081] Table 2

[0082]

[0083] In Table 2 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 crude oil is zero. According to the feed and product discharge 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 of the atmospheric and vacuum distillation unit are calculated using P iCO2 = C1 / ∑X Pi The calculation results are as follows:

[0084] P iCO2 = 0.05 / 0.95 = 0.05263158

[0085] The hydrocracking unit type is a refining unit type where both the feed carbon emission value and the unit carbon emission value are non-zero and there is a single feed. Therefore, through the following expression, the carbon footprint values of each product discharged from the hydrocracking unit are calculated:

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

[0087] The feed and product discharge information of the hydrocracking unit is as shown in Table 3 below.

[0088] Table 3

[0089]

[0090] 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. Therefore, the carbon footprint values of the hydrocracked gasoline, hydrocracked gasoline, hydrocracked diesel, and hydrocracked tail oil of the hydrocracking unit are calculated using the carbon footprint calculation model under the condition of a single feed. The calculation results are as follows:

[0091] P iCO2 = 0.1 / 0.99 + (20 / 20.3) * 0.05263158 / 0.99 = 0.15338765

[0092] The catalytic cracking unit is of the type where the refinery unit type, the carbon emission value of the feedstock, and the carbon emission value of the unit are all non-zero, and there are multiple feedstocks. Therefore, the carbon footprint value of each product discharged from the atmospheric and vacuum distillation unit is calculated through the following expression:

[0093] P iCO2 = ∑{[C2 / ∑X Pni +(∑F iCO2 / ∑F ni ) * P FiCO2 / ∑X Pni * F iCO2 * X Pni} / [∑(F iCO2 * X Pni )]

[0094] The feedstock and product discharge information of the catalytic cracking unit is shown in Table 4 below.

[0095] Table 4

[0096]

[0097] In Table 4 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. Therefore, through the carbon footprint calculation model under multiple feedstock conditions, the carbon footprint value of the catalytic liquefied gas of the catalytic cracking unit is calculated through the following expression, and the calculation result is shown below:

[0098] P iCO2 = (0.15 / 0.99 + 22.03 / 20 * 0.05263158 / 0.99) * 20 * 0.2 / (20 * 0.2 + 2.03 * 0.19) +

[0099] (0.15 / 0.985 + 22.03 / 2.03 * 0.15338765 / 0.985) * 2.03 * 0.19 / (20 * 0.2 + 2.03 * 0.19) = 0.228707503

[0100] The carbon footprint value of the catalytic gasoline of the catalytic cracking unit is calculated through the following expression, and the calculation result is shown below:

[0101] P iCO2 = (0.15 / 0.99 + 22.03 / 20 * 0.05263158 / 0.99) * 20 * 0.4 / (20 * 0.4 + 2.03 * 0.35) +

[0102] (0.15 / 0.985 + 22.03 / 2.03 * 0.15338765 / 0.985) * 2.03 * 0.35 / (20 * 0.4 + 2.03 * 0.35) = 0.228163131

[0103] The carbon footprint value of the catalytic diesel in the fluid catalytic cracking unit is calculated through the following expression, and the calculation results are shown below:

[0104] P iCO2 =(0.15 / 0.99 + 22.03 / 20 * 0.05263158 / 0.99) * 20 * 0.2 / (20 * 0.2 + 2.03 * 0.25) +

[0105] (0.15 / 0.985 + 22.03 / 2.03 * 0.15338765 / 0.985) * 2.03 * 0.25 / (20 * 0.2 + 2.03 * 0.25) = 0.230811443

[0106] The carbon footprint value of the catalytic slurry in the fluid catalytic cracking unit is calculated through the following expression, and the calculation results are shown below:

[0107] P iCO2 =(0.15 / 0.99 + 22.03 / 20 * 0.05263158 / 0.99) * 20 * 0.1 / (20 * 0.1 + 2.03 * 0.075) +

[0108] (0.15 / 0.985 + 22.03 / 2.03 * 0.15338765 / 0.985) * 2.03 * 0.075 / (20 * 0.1 + 2.03 * 0.075) = 0.227238729

[0109] The types of gasoline blending unit and diesel blending unit are those with non-zero feed carbon emission value and zero unit carbon emission value. Calculate the carbon footprint values of the respective discharged products of the gasoline blending unit and the diesel blending unit, and use the carbon footprint calculation model with non-zero feed carbon emission value and zero unit carbon emission value for calculation. Therefore, the carbon footprint values of the respective discharged products of the gasoline blending unit and the diesel blending unit are calculated through the following expression:

[0110] P iCO2 = ∑(F iCO2 * P FiCO2 ) / ∑P i

[0111] The feed and discharge information of the gasoline blending unit is shown in Table 5 below.

[0120] P iCO2 =(10 * 0.073619632 + 4.5075 * 0.218475541 + 9.947 * 0.138218421) / 24.4545 = 0.126595655
