Key Data Set Information
Location CN
Reference year 2020
Name
clinker production;clinker, portland cement clinker;new dry process, >4000 t/d
Use advice for data set Use this data set within the context of Life Cycle Assessment for estimating the environmental impacts of Portland cement clinker production using the new dry process. The data should be applied with the consideration of system boundaries specific to clinker calcination, including the preparation of pulverized coal. The upstream production data of raw materials with small quantities should be omitted accordingly, as outlined by the CLCD trade-off principle. Take into account background database uncertainties and cumulative uncertainty effects when interpreting results to ensure a comprehensive assessment.
Technical purpose of product or process The data set represents the environmental aspects of the production process of Portland cement clinker using the new dry process technology with a capacity greater than 4000 tons per day (t/d). The cement clinker produced via this process is intended for use in the construction industry for creating various grades of Portland cement.
Classification
Class name : Hierarchy level
  • ILCD: Unit processes / Materials production / Inorganic chemicals
General comment on data set The new dry process has a relatively large market share in the cement industry process. During the clinker calcination process, wastewater, particulate matter, CO2, SO2, NOx, mercury (Hg), fluorine (F), and ammonia (NH3), etc. are emitted.

General comment Particulate matter, with an unspecified particle size, is treated as PM > 10 micrometers in diameter. The particulate matter collected by the bag filter is returned to the raw material homogenization stage through the recycling system, and the solid waste generated during the process can be effectively recycled and reused.
