Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. This dataset represents the production of cement by the vertical mill system process. The production process includes cement grinding, and the water circulation process is taken into account. The data is mainly sourced from public literature and official standards. Information on the emission data inventory:
1. For the emissions of major pollutants such as CO2, the values are taken from the calculated values in public literature.
2. For the emissions of major pollutants such as SO2 and NOx, the values are taken from the measured values in public literature.
3. For the emissions of PM (≤2.5 μm), PM (2.5-10 μm), and PM (≥10 μm), the values are estimated based on the total particulate matter values and emission factors from public literature.
4. For the emissions of wastewater and inert substances, the values are estimated based on the analogy method.
5. All emissions take into account the discharge standards of the Technical Guidelines for Accounting of Pollution Source Strength in China's Cement Industry.
Activity Description
The production system boundary of this product is the grinding stage of cement production, including cement grinding, flue gas denitration, particulate matter removal, and flue gas desulfurization. The process used can basically realize the full cycle of water, and part of the loss is treated as non-recyclable waste.
Process Description
Pozzolanic Portland cement is a hydraulic cementitious material made from Portland cement clinker and pozzolanic mixed materials as the main components, mixed with an appropriate amount of gypsum and ground into fine particles. It is suitable for large-volume concrete projects on the ground, underground and in water, steam-cured concrete components, and general projects with corrosion resistance requirements.
