摘要:

为快速掌握区域内全部水泥企业的碳排放情况,在部分企业实际生产数据未知时,也能建立其生产碳排放清单,文中基于熟料生产特征,构建了可根据设备设计产能和运行时长两种参数来核算企业CO2排放的数值模型。以京津冀地区59条典型水泥熟料生产线的生产数据作为统计样本,借助Eviews对生产线的实际产能、熟料烧成煤耗与设计产能间的关系进行回归分析,并引入了生产时间修正系数,完成了CO2核算模型的建立。将其应用到京津冀地区全部106条水泥熟料生产线中,得出 2018年度京津冀地区水泥熟料总产量,该核算值与数字水泥网发布的统计数据之间的相对误差均值为7.81%。通过核算,CO2直接排放系数为0.93 t CO2/t熟料,与国内均值相差7.27%。构建的核算模型与实际生产契合良好,更重要的是可以通过此数值模型自下而上建立区域内全部企业的CO2排放清单,实现较高时空精度的清单网格化,并可与现有卫星遥感探测、移动监测设备所得的数据形成比对,使水泥行业的碳监测和减排政策的制定更具针对性。

Abstract:

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
