Use advice for data set | Users of this LCA dataset should be aware that it includes production process data from DOCC, which applies advanced RSP kiln external decomposition technology. Data was not modeled using LCA methodology but was obtained through on-site surveys and indirect calculation of energy and raw material conversion due to the lack of direct industrial pollutant emissions data. Users should also note potential methodological differences and understand that the dataset may not include end-of-life recycling or use-phase behavior modeling. It's recommended to cross-reference this data with the latest available standards and industry practices, especially regarding emission factors and environmental impacts. |
Technical purpose of product or process | This dataset represents the production of ordinary Portland cement at 42.5RMPa grade using a modern dry process with five-stage pre-calcining kiln external decomposition technology. The process is utilized in a large-scale facility capable of producing 1.9 million tons of cement annually. It is designed for the construction and building materials industry for creating concrete and other cement-based products. The facility comprises state-of-the-art production equipment from leading international and domestic manufacturers, ensuring efficient and high-quality cement production. |

Technology description including background system | The company now has a 4000t/d modern dry process production line (RSP kiln external decomposition equipment) as shown in Figure 6.2, its own independently mined open-pit limestone mine (annual limestone production capacity of 2 million tons) and a dedicated railway line in the factory. The special line for bulk cement outputs the terminal, with an annual cement production of 1.9 million tons.The company's production process adopts RSP five-stage kiln external decomposition technology, mainly using advanced production equipment from Germany, France, Japan and some domestic countries. The cement production line consists of main equipment such as a vertical raw material mill (as shown in Figure 6.1), a 5-stage RSP (pre-calcining tower outside the kiln), a rotary kiln and a large ball mill equipped with a roller press. It is also equipped with gypsum crushing and limestone crushing and conveying and adding equipment. |
