[0030] For specific implementation methods, please refer to the following embodiments.

[0031] Figure 1 The flowchart of the method for calculating the carbon footprint of coal products based on the whole life cycle provided in the embodiment of the present application is applicable to the carbon footprint calculation server. Figure 1 As shown, the method includes: step S10, step S11, step S12 and step S13.

[0032] In step S10, the coal accounting boundary is determined according to preset boundary setting requirements, preset boundary properties and preset application scenario requirements.

[0033] In this application, the preset boundary setting requirements can be determined based on the production process of coal products. For example, the production and processing process within a certain enterprise organization is used as the product production process, the production and processing process of the product in the enterprise is used as the core process, and the production process of other raw and auxiliary materials is used as the upstream process.

[0034] The boundaries of the full life cycle assessment of the product carbon footprint include cradle to gate and cradle to grave, and the boundary properties can be the different characteristics of these two boundaries. The application scenario requirements can be determined according to the nature of the enterprise. For example, some enterprises only mine raw coal without washing coal, and some enterprises both mine raw coal and wash coal. The processes involved in calculating the carbon footprint of enterprises of different natures are also different. The coal accounting boundary can also be used to indicate the processes and treatments that need to be targeted in the process of calculating the carbon footprint of coal products throughout the life cycle.

[0035] In some implementations, data collection is carried out using the cradle-to-grave system boundary, which results in a longer data collection cycle and reduced comparability; the cradle-to-gate approach is used to define the accounting boundary, and only the product carbon footprint of coal from mining to further processing and production is calculated, which makes it easier for enterprises to identify the focus of process carbon emissions and benchmark with other coal companies.

[0036] According to the example embodiment, different boundary setting requirements and different application scenario requirements can be pre-set to correspond to the coal accounting boundary used under the preset boundary properties, so as to facilitate direct matching. This application uses the coal accounting boundary from cradle to gate, which can be referred to as Figure 2 Schematic diagram of the coal accounting boundary shown.

[0037] In step S11, based on the coal accounting boundary and application scenario requirements, the coal process data corresponding to the entire life cycle is obtained.

[0038] In this application, different application scenarios involve different processes. Figure 2 , such as mining process and coal washing process, each process also involves multiple sub-processes. Based on the coal accounting boundary, it can be determined what process data needs to be collected, such as the process from mining to producing clean coal, and then the corresponding processes of the process can be matched under the application scenario requirements. Based on this, the carbon footprint accounting server can obtain the coal process data collected by the corresponding collection equipment.

[0039] In step S12, a target process unit is established according to application scenario requirements and coal process data.

[0040] In the present application, the establishment method of the target process unit can be pre-set, and according to the establishment method, the coal process data is aligned for multiple processes required by the application scenario to obtain the target process unit corresponding to each process.

[0041] In step S13, a target carbon footprint determination model for the entire life cycle is constructed according to the target process unit, the preset model association data and the preset co-product allocation method, so as to determine the carbon footprint corresponding to the coal product according to the target carbon footprint determination model and the coal process data.

[0042] In this application, the model-related data may include pre-set related parameters used to establish the model, such as loss functions, and may also include a large amount of historical process data. In the process of mining to obtain coal products, multiple processes are involved. During the processing of these processes, some symbiotic products may be produced, such as waste rock, gas, medium coal, coal slime, etc. These symbiotic products may have an impact on the environment. In order to mitigate the impact, some measures can be taken to deal with them. Therefore, the symbiotic product distribution method can be pre-set to determine the distribution method of different symbiotic products in different situations and the environmental performance of the distribution.

[0043] According to an example embodiment, a target carbon footprint determination model can be established using LCA (Life Cycle Assessment) software. The target process unit, model-related data, and a preset co-product allocation method can be imported into the software to automatically establish a model. Then, the coal process data can be input into the target carbon footprint determination model to output the carbon footprint corresponding to the coal product.

[0044] This application determines the coal accounting boundary through preset boundary setting requirements, boundary properties and application scenario requirements, ensuring the scientificity and rationality of the assessment scope. At the same time, it covers the entire life cycle of coal products, from mining, processing, transportation to use, so as to more comprehensively reflect the carbon footprint of coal products. The corresponding coal process data can be obtained according to the specific application scenario requirements, and the target process unit can be established accordingly. This flexibility enables the method to be applicable to different types of coal products and different assessment needs, improving the applicability and practicality of the assessment. In the process of coal production, a variety of symbiotic products are often produced. This application can reasonably allocate the environmental performance of these symbiotic products through the preset symbiotic product allocation method, thereby improving the accuracy of the carbon footprint of the entire life cycle.

[0045] According to some embodiments, the production and processing flow of coal products throughout the entire life cycle can be determined based on application scenario requirements; the coal accounting boundary can be determined based on boundary setting requirements, boundary properties and production and processing flow.

[0046] In this application, the production and processing flow can be used to represent the relevant data of production and processing that needs to be carried out from mining to obtaining coal products.

[0047] In some implementations, the production and processing flow of coal products under different application scenario requirements can be pre-detected and stored for direct access. A coal accounting boundary determination model can be pre-set, and the boundary setting requirements, boundary properties and production and processing flow can be input into the coal accounting boundary determination model to output the determined coal accounting boundary.

[0048] This application determines the production and processing flow of coal products according to the application scenario requirements, providing detailed basic data for subsequent carbon footprint assessment, making the assessment results closer to the actual production situation. Combining the actual production and processing flow to determine the coal accounting boundary can make the boundary more consistent with the actual production situation, and the coal process data collected based on this boundary is more comprehensive and reliable.

[0049] According to some embodiments, the corresponding process requirements can be determined according to the application scenario requirements; the corresponding data source facilities can be determined according to the process requirements and the coal accounting boundaries to obtain the coal process data detected by the data source facilities.

[0050] In this application, different application scenarios may have different requirements for the quality and specifications of coal products. According to the application scenario requirements, the corresponding coal product production process requirements (i.e. process requirements) can be matched. This includes the entire process from coal mining, washing, crushing, screening, coal blending to final product packaging, as well as the relevant requirements that need to be met in each process.

[0051] Different production processes correspond to different processing equipment. Combining process requirements and coal accounting boundaries, we can determine which data are needed, and then find out which equipment detects or obtains and stores these data. These equipment can be used as data source facilities. Then we can establish communication with the data source facilities to obtain coal process data.

[0052] This application determines the process requirements based on the application scenario requirements, and then combines the coal accounting boundary to lock the data source facilities, thereby improving the accuracy of the data source of the coal process data.

[0053] According to some embodiments, the main processes and auxiliary processes in the whole life cycle from raw material mining to waste treatment can be determined according to the application scenario requirements; according to the preset life cycle assessment method, preliminary process units corresponding to the main processes and auxiliary processes are established; according to the preset data collection requirements, the coal process data is input into the preliminary process unit to determine the target process unit.

[0054] In this application, for enterprises that only engage in mining raw coal and do not wash coal, the main processes may include underground mining or open-pit mining processes and primary screening processes, and specifically may include underground mining or open-pit mining and primary screening processes; for enterprises that only engage in coal washing and do not mine raw coal, the main processes may include coal washing processes, and specifically may include raw coal preparation (storage, crushing, screening), raw coal sorting (heavy medium, jigging, flotation, dry sorting and other processes), product dehydration and drying processes; for enterprises that engage in both mining raw coal and washing coal, the main processes include coal mining processes, and specifically may include underground mining or open-pit mining and primary screening processes.

[0055] For coal mining enterprises that only mine raw coal without washing it, or mine raw coal and wash it, auxiliary processes may include the production and transportation of energy, the acquisition of auxiliary materials, and supply chain transportation. Among them, the production and transportation of energy refers to the energy source used to drive the production process, including the production, transportation and emission of energy (electricity, heat, diesel, water, etc.); the acquisition of auxiliary materials and supply chain transportation should provide data according to the actual transportation mode, distance and vehicle load, or provide data according to the actual consumption of auxiliary materials. For enterprises that only wash coal, auxiliary processes may include the production and transportation of energy, the acquisition of raw materials (raw coal) and auxiliary materials, and supply chain transportation. Among them, the production and transportation of energy refers to the energy source used to drive the production process, including the production, transportation and emission of (electricity, heat, diesel, water, etc.); the acquisition of auxiliary materials and supply chain transportation should provide data according to the actual transportation mode, distance and vehicle load, or provide data according to the actual consumption of energy (including gas escape, combustion and recycling data in the actual mining process).

[0056] The life cycle assessment method in this application is LCA, and the LCA software is used to establish preliminary process units corresponding to the main process and auxiliary process. The preset collection requirements can be used to represent the collection method of data corresponding to different processes. For example, for enterprises that only engage in mining raw coal and do not wash coal, the data that need to be collected corresponding to the main process at least include the annual output of raw coal, auxiliary material consumption, fuel consumption, water resource consumption, electricity consumption, heat consumption, coal gangue / coal slime / industrial wastewater / industrial waste gas generation and emission, gas extraction / utilization / emission / destruction (venting combustion), etc. For enterprises that only engage in coal washing and do not mine raw coal, the data that need to be collected corresponding to the main process at least include the annual output of clean coal, auxiliary material consumption, fuel consumption, water resource consumption, electricity consumption, heat consumption, annual output of medium coal / coal slime / coal gangue, gas escape, etc. For enterprises engaged in both raw coal mining and coal washing, the data that need to be collected for the main processes include at least the annual output of raw coal, auxiliary material consumption, fuel consumption, water resource consumption, electricity consumption, heat consumption, coal gangue / coal slime / industrial wastewater / industrial waste gas generation and emission, gas extraction / utilization / emission / destruction (venting combustion), annual output of clean coal, auxiliary material consumption, fuel consumption, water resource consumption, electricity consumption, heat consumption, annual output of medium coal / coal slime / coal gangue, gas emission, etc. The data that needs to be collected for the auxiliary processes can also be set in advance and then used as data collection requirements as a whole.

[0057] Then, according to the data collection requirements, the sources of different coal process data can be determined, and then the coal process data can be input into the corresponding preliminary process unit to obtain the target process unit.

[0058] This application can scientifically and accurately divide the main processes and auxiliary processes in the entire life cycle from raw material mining to waste treatment according to application scenario requirements and coal process data. This detailed division helps to understand the production process of coal products more accurately and provides a basis for subsequent data analysis and evaluation. Through the preset data collection requirements, the coal process data is input into the preliminary process unit, thereby determining the target process unit and improving the accuracy of the generated target process unit.

[0059] According to some embodiments, the coal process data can be input into the preliminary process unit according to the preset data collection requirements to determine the basic process unit; determine the raw materials and auxiliary materials of the whole life cycle; for each basic process unit, when the raw materials and / or auxiliary materials of the basic process unit are not purchased products, determine the basic process unit as the target process unit; when the raw materials and / or auxiliary materials of the basic process unit are purchased products, obtain the background data of the raw materials and / or auxiliary materials; input the background data into the corresponding position of the basic engineering unit to determine the corresponding target process unit; when the raw materials and / or auxiliary materials of the basic process unit are the process products corresponding to the associated process unit, associate the basic process unit with the associated process unit.

[0060] In this application, the background data of raw materials and / or auxiliary materials can characterize the energy consumption and emissions of these purchased products during the production process. The associated process unit can be used to represent other basic process units in the basic process unit except for a basic process unit that uses purchased products as raw materials and / or auxiliary materials.

[0061] In some implementations, first, according to the above steps, the coal process data is input into the preliminary process unit to obtain the basic process unit. Then, the pre-stored raw materials and auxiliary materials of the whole life cycle can be obtained. For each basic process unit, if the raw materials and / or auxiliary materials of the unit are not purchased products, the basic process unit can be used as the target process unit.

[0062] If the raw materials and / or auxiliary materials of the unit are purchased products, background data can be obtained from the purchase source and input into the relevant position in the corresponding unit, that is, the position of the purchased product is used to obtain the target process unit.

[0063] When the raw materials and / or auxiliary materials of any basic process unit are the process products of the associated process unit, the upstream and downstream processes can be linked by referencing the upstream process products. That is, after the associated process unit is processed, the process product is obtained, which may be used as the raw materials and / or auxiliary materials of a basic process unit. At this time, the two units can be linked.

[0064] This application comprehensively considers the material input in the production process by obtaining raw materials and auxiliary materials throughout the entire life cycle. This comprehensive consideration helps to more accurately evaluate the environmental impact and resource utilization efficiency of the production process. For any basic process unit, based on the source of its raw materials and / or auxiliary materials, accurately identify whether the basic process unit needs to be determined as the target process unit. For purchased raw materials and / or auxiliary materials, by obtaining their background data and inputting them into the corresponding basic engineering units, effective data integration is achieved. When the raw materials and / or auxiliary materials of any basic process unit are the process products corresponding to the associated process unit, by connecting it with the associated process unit, the coordination and association between different process units in the production process is achieved. This coordination helps to more accurately evaluate the environmental impact and resource utilization efficiency of the entire production process, and promote the continuous optimization of the production process.

[0065] According to some embodiments, the direct discharge information of the target process unit can also be obtained; when the direct discharge information includes carbon dioxide direct discharge, the carbon dioxide direct discharge amount is determined according to the corresponding coal process data for the target process unit corresponding to the carbon dioxide direct discharge; and the carbon dioxide direct discharge amount is configured to the target process unit corresponding to the carbon dioxide direct discharge.

[0066] In this application, direct emission information can be used to characterize the direct emission of various pollutants generated by different target process units after material processing. Carbon dioxide direct emission can be used to indicate direct emission of carbon dioxide.

[0067] In some implementations, the material handling process of each target process unit can be monitored and detected, and the detected direct emission information can be stored. Analyze whether the direct emission information contains direct carbon dioxide emissions. If so, the direct carbon dioxide emissions can be calculated based on the coal process data in the corresponding target process unit. In other implementations, the calculated direct carbon dioxide emissions can be compared with the detected direct carbon dioxide emissions to determine the actual direct carbon dioxide emissions, and then the value is configured in the corresponding target process unit. For target process units with direct carbon dioxide emissions, it is necessary to determine the direct carbon dioxide emissions based on the corresponding coal process data. This can usually calculate the amount of carbon dioxide generated in coal combustion processes, chemical reaction processes, or waste gas treatment processes. Professional emission factors, chemical equilibrium equations, or mathematical models may need to be used in the calculation process. If there is no direct carbon dioxide emission, no subsequent operations are required.

[0068] By obtaining the direct emission information of the target process unit, this application can fully understand the direct emissions in the production process and more accurately assess its environmental impact, especially the emission of greenhouse gases such as carbon dioxide. When the direct emission information includes direct carbon dioxide emissions, the technology can accurately calculate the direct carbon dioxide emissions based on the corresponding coal process data, avoid underestimation or overestimation of emissions, and thus provide more accurate emission data. The calculated direct carbon dioxide emissions are configured in the corresponding target process unit, realizing a close association between the data and the process unit.

[0069] According to some embodiments, a life cycle assessment method can be determined according to preset model establishment requirements; a basic carbon footprint determination model can be established based on the life cycle assessment method, the target process unit and the model-related data; corresponding emission factors are configured for the process unit modules corresponding to the target process units in the basic carbon footprint determination model, and the co-product allocation method is integrated into the basic carbon footprint determination model to determine the carbon footprint determination model; and the coal process data is input into the target carbon footprint determination model to determine the carbon footprint of the coal product.

[0070] In this application, model building requirements can be used to characterize restrictions on the model building process, model capabilities, etc. The basic carbon footprint determination model can be a model that includes a framework and basic capabilities. The emission factor is a coefficient corresponding to the activity level data, which is used to quantify the greenhouse gas emissions or pollutant emission intensity per unit activity level. This application can use the official carbon accounting guidelines or advanced carbon emission factors provided by authoritative organizations such as the IPCC.

[0071] In some implementations, life cycle assessment methods corresponding to different model establishment requirements are pre-set to find and determine the life cycle assessment methods corresponding to the requirements. According to the production process of coal products, key target process units are identified, such as mining, washing, transportation, combustion, etc. The model-related data related to each target process unit are sorted out, including energy consumption, material use, type and quantity of emissions, etc. Based on the life cycle assessment method and the target process unit, the structure of the basic carbon footprint determination model is constructed, including input, processing and output modules. According to the data association and logical relationship, a mathematical model is established to calculate the carbon emissions of each process unit to obtain the basic carbon footprint determination model.

[0072] Configure the selected emission factors to the corresponding process unit modules in the basic carbon footprint determination model to ensure that the carbon emissions of each process unit are accurately calculated. According to the preset co-product allocation method, the carbon emissions of co-products are reasonably allocated to the main products and by-products. Integrate the co-product allocation method into the model to obtain the carbon footprint determination model, and then the coal process data can be input into the target carbon footprint determination model to output the determined carbon footprint of the coal product.

[0073] This application can accurately quantify the carbon emissions of coal products at each production stage by constructing a target carbon footprint determination model for the entire life cycle, including the entire life cycle links such as raw material mining, processing and production, transportation, use and waste disposal, so that enterprises can have a more comprehensive understanding of the carbon emissions of coal products. The life cycle assessment method, target process unit identification, model-related data collection and emission factor configuration adopted in this application are all based on scientific methods and rigorous data, ensuring the accuracy and reliability of carbon footprint calculations. At the same time, the integration of the symbiotic product allocation method into the model further improves the comprehensiveness of the carbon footprint calculation.
