[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0023] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.
[0024] Figure 1 FIG. 1 is a flow chart of a method for determining a product thermal emission factor provided by an exemplary embodiment of the present disclosure. Figure 1 As shown, the method includes steps S101 to S103.
[0025] In step S101, thermodynamic balance information is determined according to the production process of the product.
[0026] The thermodynamic balance information includes the heat and heat transfer information of each steam level. The heat transfer information may include the source and destination of the heat. In one embodiment, the required thermodynamic balance information may be obtained through a pre-built thermodynamic balance diagram of the product. In one embodiment, the heat of any steam level may be determined based on the steam quality of the steam level and the corresponding steam enthalpy value.
[0027] In step S102 , for each steam level, the level consumption thermal emission factor of the steam level is determined according to the thermal energy transfer information of the steam level.
[0028] In one embodiment, the source and destination of the steam level can be determined based on the heat energy transfer information of the steam level, and the method for determining the level consumption thermal emission factor corresponding to different sources is different. For example, if the steam of this steam level is the highest level of steam, that is, the steam all comes from the combustion of fossil fuels, then the preset value can be determined as the level consumption thermal emission factor of the steam level, where the preset value can be determined based on historical carbon emission data. For another example, if part of the steam of this steam level comes from the combustion of fossil fuels, the level consumption thermal emission factor of the current steam level can be determined based on the principle of conservation of heat and combined with the level consumption thermal emission factor of the previous steam level. For another example, if the steam of this steam level all comes from waste heat or renewable energy heat generation, no carbon emissions are generated at this time, and the level consumption thermal emission factor of the steam level can be determined as 0. In this way, the contribution of different steam levels to thermal emissions can be accurately quantified.
[0029] In step S103, the product consumption heat emission factor is determined according to the heat of each steam grade and the grade consumption heat emission factor.
[0030] In one embodiment, the product consumption heat emission factor can be determined based on the total heat required (consumed) in the product production process, the heat of each steam level and the level consumption heat emission factor. By monitoring and counting the heat generation and consumption of all production units at different steam levels in the whole plant, combined with the level consumption heat emission factor of each steam level, the product consumption heat emission factor during the production of different products can be accurately calculated.
[0031] In this way, based on thermal balance, with the products to be included in the control as the boundary and without considering the impact of heat-consuming devices outside the product production boundary, the determined product thermal emission factor can be made more accurate and more representative of the actual emissions of the product, so as to achieve the purpose of thermal emissions truly reflecting the actual carbon emissions of the product production process, thereby improving the quality of carbon emission data.
[0032] In the above technical scheme, the thermodynamic balance information is determined according to the production process of the product to clarify the thermodynamic balance state of each steam grade; for each steam grade, the grade consumption thermal emission factor of the steam grade is determined according to the heat energy transfer information of the steam grade, which can accurately quantify the contribution of different steam grades to thermal emissions; the product consumption thermal emission factor is determined according to the heat and grade consumption thermal emission factor of each steam grade, which can make the determined product consumption thermal emission factor more in line with the actual emission situation of product production, thereby improving the quality of carbon emission data and ensuring the fairness of carbon trading.
[0033] In an optional embodiment, in step S101, the thermodynamic balance information is determined according to the production process of the product, including: Generate a thermodynamic balance diagram based on the product production process. The thermodynamic balance diagram is used to indicate the steam level and heat transfer information of different production processes. For each steam level, the heat of the steam level is determined based on the steam quality and steam enthalpy of the steam level.
[0034] For example, the source and destination of steam (heat transfer information) can be obtained based on the actual production process and measurement of the enterprise. The steam level can be pre-set according to the production process design, and different steam levels correspond to different steam pressures. A thermodynamic balance diagram can be generated based on the steam level and heat transfer information of the production process. Taking coal-to-methanol production as an example, its thermodynamic balance diagram is as follows: Figure 2 As shown, each steam pressure corresponds to a steam level. Figure 2 There are 5 different steam levels involved. For each steam level, the product of the steam quality and steam enthalpy of the steam level can be determined as the heat of the steam level. In this way, through the construction of the heat balance diagram and the confirmation of the heat of each steam level, the system can have a more comprehensive understanding of the operating status of the thermal system, clarify the thermal balance status of each steam level, provide data support for subsequent calculations, and help ensure the stability and efficiency of the thermal system.
[0035] In an optional embodiment, in step S102, determining the level consumption heat emission factor of the steam level according to the heat energy transfer information of the steam level includes: If the heat energy transfer information characterizes that the direct source of steam for a steam grade is all fossil fuel combustion, the grade consumption heat emission factor for the steam grade is determined based on the steam generating equipment.
[0036] For example, if the heat transfer information indicates that the direct source of steam of a steam grade is all fossil fuel combustion, then the steam of this steam grade can be determined to be the highest grade steam, that is, its direct source is a power plant or boiler. At this time, the grade consumption heat emission factor of the steam grade can be determined in the following way: If the steam generating equipment is a steam boiler, the ratio of boiler emissions to boiler heat supply is determined as the grade-consumption heat emission factor for the steam grade; If the steam generating facility is a power plant, the carbon emission intensity of heat supply is determined as the heat emission factor for the steam grade consumed; If the boiler emissions or boiler heating capacity cannot be obtained when the steam generating equipment is a steam boiler, or if the heating carbon emission intensity cannot be obtained when the steam generating equipment is a power plant, the preset value will be determined as the grade consumption thermal emission factor of the steam grade.
[0037] For example, boiler emissions and boiler heat supply can be collected and calculated through relevant technologies, which will not be expanded here. The heating carbon emission intensity is the carbon dioxide emissions generated per unit of heat supply during the heating process, and the heating carbon emission intensity can be determined by the method of determining the heating carbon emission intensity in the relevant technology. If the required data cannot be obtained, for example, when the steam generating equipment is a steam boiler, the boiler emissions or boiler heat supply cannot be obtained, or when the steam generating equipment is a power plant, the heating carbon emission intensity cannot be obtained, then the preset value can be determined as the steam grade level consumption thermal emission factor. The preset value can be determined based on historical carbon emission data, for example, it can be 0.11.
[0038] In an optional embodiment, in step S102, determining the level consumption heat emission factor of the steam level according to the heat energy transfer information of the steam level includes: If the heat energy transfer information represents that the direct source of steam of a steam grade is partly fossil fuel combustion, the grade consumption heat emission factor of the current steam grade is determined based on the grade consumption heat emission factor of the previous steam grade.
[0039] For example, if the heat transfer information characterizes that the direct source of steam for the steam grade is partly fossil fuel combustion, then the other part of the steam may be generated in the process of cooling and decompression, steam turbine, etc. At this time, the principle of heat conservation can be combined to achieve accurate calculation of the thermal emission factor of the current steam grade. For example, in the high-grade (also understood as the previous grade) steam cooling and decompression process, the steam heat before and after cooling and decompression can be considered to be conserved, and the high-grade heat can be considered to be consumed and converted into low-grade steam. Then the high-grade steam is used as the consumption end, and the low-grade steam can be directly used in subsequent processes, so the low-grade steam is used as the generation end.
[0040] For example, the level consumption heat emission factor for the current steam level can be determined by the following formula:
[0041] in, To produce products The first The grade consumption heat emission factor of the steam grade, in tCO2 / GJ; To produce products The first The grade consumption heat emission factor of the steam grade, in tCO2 / GJ; For the The heat generated by non-waste heat in the steam grade, in GJ; For the The total heat consumed by all heat-consuming equipment in the steam level, in GJ. The first steam level consumed in the process is the highest steam level, that is, the direct source of steam under the first steam level is all fossil fuel combustion. In addition, the value of the thermal emission factor of the first steam level is greater than the thermal emission factors of other steam levels.
[0042] In an optional embodiment, in step S102, determining the level consumption heat emission factor of the steam level according to the heat energy transfer information of the steam level includes: If the heat transfer information indicates that the direct source of steam for a steam grade is all waste heat or renewable energy, the grade consumption heat emission factor for determining the steam grade is 0.
[0043] For example, if the steam of this steam grade comes entirely from waste heat or renewable energy heat, no carbon emissions are generated at this time. Therefore, the grade-consumption thermal emission factor of this steam grade can be determined as 0.
[0044] In an optional embodiment, in step S103, the product consumption heat emission factor is determined according to the heat of each steam level and the level consumption heat emission factor, including: The product is determined by the following formula Heat emission factor for product consumption:
[0045] in, For products Thermal emission factor of product consumption, To produce products The first The heat of the steam grade in GJ; To produce products The first The grade consumption heat emission factor of the steam grade, in tCO2 / GJ; To produce products The total calories consumed in the process.
[0046] In this way, based on the heat generation and consumption of all production units under different steam levels and combined with the heat emission factors of each steam level, the heat emission factors of product consumption in the production process of different products can be accurately calculated, so that the determined product heat emission factors are more in line with the actual emissions of product production, thereby improving the quality of carbon emission data and ensuring the fairness of carbon trading.
