Description

New dry process kiln is used for the production of portland cement. A study was conducted on the process flow and operating parameters of the new dry-process technology currently available in the cement industry in Heilongjiang Province, and input and output data of the established product system were collected and calculated and quantified. When utilizing this LCA data for the cement production process, ensure that the data corresponds accurately to the new dry process kiln technology. In modeling the cement production lifecycle, exclude the environmental load caused by the consumption of clay resources and the environmental impact due to the use of iron powder as a correction material. Consider the emissions of nitrogen oxides, sulfur dioxide, carbon dioxide, and dust in the impact assessment, as these are significant pollutants emitted from the cement production. The functional unit of the dataset is based on 1kg of cement with a 28-day compressive strength of 42.5MPa.
