(Shandong, China)山东申丰水泥集团有限公司（中国山东）The data set describes a large-scale dry rotary kiln operation for the production of common Portland cement. This process is mainly applied for the generation of clinker at a rate higher than 4000 tons daily. The recycled cement dust and reused wastewater underscore an environmentally considerate manufacturing practice. The cement produced here is typically used in construction, and is the predominant form of cement in the Chinese market, comprising about 98% of the total cement production.该数据集描述了一种用于生产通用硅酸盐水泥的大型干法回转窑操作过程。该过程主要用于以每天4000吨以上的速度生成熟料。再循环的水泥粉尘和再利用的废水突显出环保的制造实践。此处生产的水泥通常用于建筑领域，在中国市场是水泥的主要形式，约占总水泥产量的98%。BmREbAzZso5kNPx6deCcfQMfn6g.pngTaking the production of 1 ton of ordinary Portland cement as a functional unit, this type of cement accounts for approximately 98% of total production in China.Dry rotary kiln system boundary. Three stages are usually considered, namely raw material crushing, clinker generation and cement mill. The clinker generation stage includes homogenization, preheating and precalcining as well as firing in the kiln. Each process takes into account raw materials, energy consumption, road transport, direct emissions (i.e. carbon dioxide, sulfur dioxide, nitrogen oxides and particulate matter) and infrastructure.以生产1吨普通硅酸盐水泥作为功能单位，该种水泥在中国约占总产量的98%。干法回转窑系统边界。通常考虑三个阶段，即原材料破碎、熟料生成和水泥磨。熟料生成阶段包括均化、预热和预分解以及在窑中的烧成。每个过程都考虑了原材料、能源消耗、道路运输、直接排放（即二氧化碳、二氧化硫、氮氧化物和颗粒物）和基础设施。Unit process, black boxNone无None无None无For the large-scale production scenario, annual statistical and monitoring data from Shenfeng Cement Co., Ltd. in Shandong Province, China, were used. Due to the lack of information on the former, direct atmospheric emission data come from Yunnan Hongda Cement Plant.对于大规模生产情景，使用了来自中国山东省申丰水泥有限公司的年度统计和监测数据。由于前者缺乏信息，因此直接大气排放数据来源于云南宏达水泥厂。None无None无Wei Chen, Jinglan Hong, & Changqing Xu.

When using this data set for Life Cycle Assessment (LCA), ensure to include the complete system boundary spanning raw material crushing, clinker generation, and cement milling stages. Pay special attention to the allocation of environmental loads regarding the 100% recycling of cement dust and reuse of wastewater on-site. Methodological considerations should cover the sourcing of emission data due to reported information gaps, and adjustments may be required based on the technological differences between referenced facilities (Shenfeng Cement Co., Ltd. and Yunnan Hongda Cement Plant).在使用此数据集进行生命周期评估（LCA）时，请确保包括原材料破碎、熟料生成和水泥磨的完整系统边界。特别注意应对现场回收的100%水泥粉尘和废水回用的环境负荷分摊。方法论上应考虑由于报告信息缺失而需获取排放数据的事宜，可能需要根据参考设施（山东申丰水泥有限公司和云南宏达水泥厂）的技术差异进行调整。Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044.清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。Tiangong LCI Data Working Group天工LCI数据工作小组#REF!, ysqsophia@gmail.comysqsophia@gmail.comysqsophia@gmail.com2024-03-19T21:18:09+08:002024-04-20T14:41:46.082200+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=e04fa2b0-b021-4297-ac0e-5911aca647f1&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and usescalcium carbonateInput1050.01050.0Limestone石灰石gypsumInput50.5150.51Gypsum石膏waterInput360.0360.0Water水sandstoneInput54.8154.81Sandstone砂岩Pyrite cinderInput14.6414.64Pyrite cinder黄铁矿煤渣ashInput241.39241.39Fly ash粉煤灰hard coal; 26.3 MJ/kgInput101.94101.94Coal煤炭ElectricityInput294.94800000000004294.94800000000004Electricity电力carbon dioxide (fossil)Output620.0620.0CO2.
