In this paper, a numerical model was developed based on the design capacity and operating time of equipment to grasp the carbon emission situation and establish production carbon emission inventory of cement companies in the case of actual production data is unknown. The accounting model of CO2 was established with 59 typical cement clinker production lines in the Beijing-Tianjin-Hebei region as statistical samples, and the production time as correction factor. Meanwhile, the relation of design capacity with actual production and specific energy consumption was fitting by Eviews respectively. The results showed that the relative error between the total output calculated by model of cement clinker in the Beijing-Tianjin-Hebei region in 2018 and the statistical data released by Digital Cement Network is 7.81%. In addition, the direct CO2 emission coefficient was 0.93 t CO2/t C, which was 7.27% difference with the domestic average data. The constructed accounting model is in good agreement with actual production. More importantly, this numerical model can be used to establish the CO2 emission inventory of all cement enterprises in the region from bottom to up to achieve inventory grids with high spatio-temporal accuracy. Moreover, the numerical model could lead to more targeted carbon monitoring and emission reduction policies by compared with the data obtained from existing satellite remote sensing detection and mobile monitoring equipment.

Key words: CO2 emission calculation, Cement clinker production enterprise, CO2 emission inventory, Actual production capacity, Cement clinker burning coal consumption, Production time
