Key Data Set Information
Location BJ-CN
Geographical representativeness description A cement plant in Beijing
Name
cement production;cement, ordinary portland cement, 52.5MPa;dry process rotary kiln
Use advice for data set When using this dataset, researchers and analysts must be aware that it only accounts for the environmental impact of the direct raw material consumption and waste emissions from the production process, excluding the production and processing of the raw materials themselves. Additionally, CO2 emissions data is not included in this dataset, which must be considered if assessing the overall environmental impact of the process. When utilizing this data for life cycle assessment or related environmental studies, it is essential to account for these limitations and possibly supplement with additional data where relevant.
Technical purpose of product or process The described industrial process pertains to the production of 52.5MPa ordinary Portland cement using a new dry process rotary kiln system. This process is used in the manufacture of cement in a plant located in the Beijing area. The cement produced can be employed in various construction applications, such as building infrastructure, creating concrete structures, and other civil engineering works where high-grade cement is required.

Mathematical model
Model description Combined with the characteristics of the cement production process itself, the research scope is defined as: from raw material entering the factory, raw material pretreatment, raw meal grinding, raw meal calcination, clinker grinding, until cement homogenization, storage, and packaging. The production and processing process of raw materials is not considered here, only the impact of the production process on the environment is considered, that is, the process of direct raw material consumption and direct waste emissions. Taking the performance of 1 ton of 525# ordinary Portland cement as a functional unit, 1Fu=52.5tMPa.
