Description

Method, device, equipment and storage medium for calculating carbon footprint value of products in refining and chemical systems

[0001] Related applications

[0002] This application claims priority to the Chinese invention patent application with application number 202311821211.7 filed on December 27, 2023, and cites the entire disclosure of the above patent application as part of this application. Technical Field

[0003] The present disclosure relates to the field of carbon emission technology, and in particular to a method and apparatus, equipment, and storage medium for calculating the carbon footprint value of products in a refining system. Background Art

[0004] The production of refining and chemical products is complex, involving numerous units, complex processes, and numerous products. The factors contributing to carbon emissions throughout the entire production process are diverse. For example, different products and units generate varying carbon emissions, resulting in a similarly diverse carbon footprint. This is especially true for large-scale refining and chemical systems, where multiple units are interconnected. This raises the issue of carbon footprint transfer.

[0005] At present, the relevant technologies for calculating carbon emissions can use some calculation methods to perform simple calculations on the carbon emissions of the entire process, calculate the total carbon emissions of petrochemical products in the production process, and calculate the carbon emission coefficients of petrochemical equipment for different products; the process carbon emissions caused by the production link are generally all counted in a certain specific product, and the petrochemical equipment is also considered separately in the calculation process, without considering the mutual relationship between petrochemical equipment. Summary of the Invention

[0006] The inventors of this application have discovered that current technologies fail to properly allocate carbon emissions generated during the production process to individual products, effectively calculating the carbon footprint of refined products. Furthermore, existing methods for calculating the carbon footprint of refined products fail to delve into the detailed details of the refining process itself. Instead, they simplify the carbon emissions of the entire process and attribute all process emissions to specific products. These methods fail to consider the impact of other byproducts or other material outputs on carbon emissions allocation, nor do they consider the carbon footprint transfer relationships between units. Consequently, they cannot accurately determine the carbon footprint of a refining system.

[0097] The hydrocracking unit is a secondary processing unit and the feed includes the discharge of a constant pressure reduction unit. The feed and discharge information of the hydrocracking unit are shown in Table 3 below.

[0098] Table 3

[0099] When the carbon emission allocation requirement is to allocate according to product value, the carbon footprint value of the secondary processing device product is calculated based on the following expression: iCO2 =C2*a i / ∑(X Pi *a i )+(∑F iCO2 / ∑F i )*P FiCO2 *a i / ∑(X Pi *a i )

[0100] In Table 3 above, all dry gas components and unit losses are not allocated carbon emissions and do not participate in the carbon footprint calculation.
