Electrolytic aluminum enterprises:
According to the Greenhouse Gas Emission Accounting and Reporting Requirements of aluminum smelting enterprises, input parameters of emission sources can be set. Enterprises can add data related to fossil fuel combustion (fuel consumption, low calorific value, etc.) manually or automatically (system connection or data import). According to the embedded formula, the system will automatically calculate their emissions. At the same time, various verification materials can be uploaded, and other production data (such as monthly data) can be added to further verify the credibility of the data. In addition, emission factors such as carbon content per unit calorific value, carbon oxidation rate and other optional default values will be automatically adjusted by the system to include the recommended values of "Requirements" into the calculation, thus reducing the reporting difficulty for enterprises.
Enterprises can add energy into the system to use as raw material emissions data, including primary aluminum output, net consumption of tons of aluminum carbon anode, average sulfur content, average ash content, etc., the system will calculate emissions according to the logic formula of "Requirements"; At the same time, various verification materials can be uploaded and other relevant data (such as monthly data) can be added for further verification of the credibility of the data; Among them, if some data have no measured values, the recommended values of requirements can be selected, and the system will automatically retrieve the background input data.
This page must be enterprise entry process emissions carbon anode effect of fluoride all relevant data, such as output, carbon tetrafluoride HuaEr and six fluorine carbon emissions of global warming potential and factors (such as no measured values, can choose the recommended value of the journal requirements, system can obtain your background data), according to the requirements of logic formula emissions of anode effect; Meanwhile, enterprises can upload data corresponding to validation materials (such as monitoring records) and add other auxiliary data (such as monthly data) to help cross-validation data.
Enterprises can add all kinds of carbonate decomposition emission data on this page, including consumption and emission factor (the recommended value of requirements can be selected, and background data will be automatically retrieved by the system). The system can calculate corresponding emissions according to the logical formula of Requirements. At the same time, enterprises can upload data validation materials and add other production data (such as monthly consumption) to help cross-validation data.
Enterprises can add data involved in the process of carbon dioxide recovery and utilization on this page, including gas volume, gas purity, etc. The system will calculate the amount of carbon dioxide recovery according to the logic formula of "Requirements"; At the same time, data verification materials (enterprise books or statistical statements, etc.) can be uploaded, and other auxiliary data in this process can also be added to help verify the credibility of data.
Similarly, the enterprise can manually or automatically add the activity data related to electric power emission (including purchased electric power, exported electric power and power consumption of other products), and the system can automatically adjust the regional grid emission factor according to the geographical location of the enterprise, and calculate the corresponding emissions according to the logic formula of "Requirements"; You can also upload all kinds of verification materials (invoice or statement) and add other relevant data (such as monthly electricity consumption) to verify the credibility of the data.
On this page, enterprises are required to add activity data and emission factor related to heat use (purchased heat, exported heat, and heat used for other products) (if there is no measured value, the recommended value of requirements can be selected, and background data will be automatically retrieved by the system), and the used heat emissions can be calculated according to the logic formula of Requirements; Meanwhile, enterprises can upload data verification materials (thermal meter readings, settlement vouchers, etc.), add other auxiliary data (such as monthly data), conversion coefficient (conversion between GJ and T), and cross-verify the credibility of data
After the enterprise completes adding the above emission source data, the system will automatically process and summarize its emissions and display them in the form of a table. The data in this table will be updated as the data of each emission source is adjusted.
According to the National Development and Reform Commission on earnestly the national carbon emissions trading market launch the key work of the notice, the enterprise can be in the page to add the electrolysis process level communication power consumption of the supplementary data, including liquid aluminum output, power consumption and emissions by the electrolytic process, the system will collect classified according to the new facility and the existing infrastructure all electrolytic process and the corresponding power consumption carbon emissions.
